How do I log in to DIBBS?

Go to the DIBBS portal at dibbs.bsm.dla.mil and sign in from the vendor login link. For ordinary vendor quoting you use a DIBBS username and password tied to your CAGE code. A DoD PKI certificate or CAC is not required to search solicitations or submit an RFQ quote, though some functions have historically asked for one. Three things trip up most vendors. Passwords expire every 60 days, so if you log in only occasionally expect a reset almost every visit, and reset from the login page rather than creating a second account. Idle accounts get locked or terminated, so sign in at least monthly, and note that three failed password attempts locks you out as well. And DIBBS is a DoD site that expects the DoD root certificates, so install the DoD certificate chain before you assume a certificate warning means your account is broken. If your account is locked or your CAGE code is not recognized, contact the DLA Enterprise Help Desk. Account problems are almost always a SAM.gov registration that has lapsed, not a DIBBS fault.

Do I need to register on DIBBS to sell to DLA?

Yes. DIBBS registration is required to submit quotes on DLA solicitations electronically. You also need an active SAM.gov registration with a valid CAGE code before you can create a DIBBS account, because DIBBS pulls your company details from SAM.

How do I know if I am allowed to quote a DIBBS solicitation?

Check the part's source-approval status before anything else. DLA records the CAGE codes it approves to supply each stock number, and the Acquisition Method Suffix Code on the solicitation says whether that list is a gate or a history. If the item is openly competable, any capable supplier may quote and the listed sources are simply who has supplied it before. If it is restricted to approved sources, DLA will not evaluate a quote from a CAGE outside the list. About 72% of the parts on open DIBBS solicitations are restricted to approved sources, and on roughly a quarter DLA lists exactly one. CLEATUS shows the approved suppliers and that status directly on the solicitation. On DIBBS you have to work it out from the technical data.

What is an AMSC code on a DIBBS solicitation?

The Acquisition Method Suffix Code tells you whether the government owns a complete technical data package for the item or has to buy from a controlled source. Some codes mean the design is fully documented and open to any qualified supplier. Others mean the design is controlled and only approved sources may quote. A part with no AMSC published is not a restricted part. It means the code was never recorded, so confirm technical data availability with the buyer before you invest quote time.

How do I look up an NSN for free?

The catalog is federal public record data. CLEATUS publishes all 17 million DLA stock numbers at cleat.ai/government/nsn with no account required. Search by stock number, manufacturer part number, or item name, and each part page shows what the item is, its approved sources, and the DIBBS solicitations and awards that named it. Dashed, undashed, and bare-NIIN spellings all resolve to the same part.

What is the DLA no bid list?

There is no published DLA no bid list to look up. What exists is the no-bid response itself: on a DIBBS request for quotation you can select No-Bid as the Bid Type, either to decline the item outright or to withdraw a quote you already submitted by replacing it. Recording a no-bid beats letting the solicitation lapse in silence, because it puts an explicit response on the record instead of nothing at all. If you are getting a stream of items you never quote, the fix is your notification settings rather than your response habits. DIBBS alerts are driven by the Federal Supply Classes you subscribe to, so narrow that list to the classes you actually supply.

Is DIBBS the same as SAM.gov?

No. SAM.gov is the government-wide system for entity registration and federal opportunity search. DIBBS is DLA-specific and handles solicitations and quotes exclusively for DLA supply items. You need both, but they serve different functions.

What is the relationship between DIBBS and FedMall?

FedMall (formerly DOD EMALL) is DLA's e-commerce platform where government buyers purchase items directly from vendor catalogs. DIBBS is the solicitation and bidding side. Some contractors use both: DIBBS for competitive solicitations and FedMall for catalog-based sales.

Can I use DIBBS for services contracts?

DIBBS is primarily for supply items. DLA does award services contracts such as facility services, logistics, and IT, but those typically flow through SAM.gov and other procurement vehicles rather than DIBBS.

How often are new solicitations posted on DIBBS?

DLA processes over 10,000 contract actions daily, so new solicitations appear continuously. That volume is precisely why manual monitoring is impractical, and why automated discovery gives you a real advantage.

What happened to FPDS, and does it affect DIBBS?

FPDS.gov was decommissioned on February 24, 2026, and contract award data moved to SAM.gov. DIBBS is unaffected and remains operational as DLA's solicitation portal. The broader trend of government system consolidation is part of why contractors are moving to platforms that aggregate award and solicitation data from multiple sources.

DLA DIBBS: Login & How to Win DLA Contracts

The Defense Logistics Agency processes over 10,000 contract actions every day and obligated $55.4 billion in FY2025 alone. DIBBS — the DLA Internet Bid Board System — is the front door to roughly 85% of those solicitations. But if you've ever tried to navigate DIBBS, you know the front door doesn't exactly roll out a welcome mat. Here's what DIBBS is, how to use it, and why contractors who rely on it as their primary discovery tool are leaving money on the table.

TL;DR

DIBBS is the Defense Logistics Agency's web-based portal for searching and quoting on RFQs, RFPs, and IFBs for DLA supply items.
DLA is massive: $55.4 billion in obligations in FY2025, over 5 million managed items, and 10,000+ contract actions processed daily.
85% of DLA solicitations flow through DIBBS — covering spare parts, consumables, fuel, medical supplies, uniforms, construction materials, and more.
The interface is a known pain point: code-based searching (NSN, FSC, CAGE), 60-day mandatory password resets, limited filtering, and no intelligent matching.
Approved sources decide the bid before price does: about 72% of the parts on open DIBBS solicitations are restricted to DLA-approved sources, and on roughly a quarter of them DLA lists exactly one approved supplier.
CMMC Phase 2 is suspended. The Department of War paused third-party certification on July 13, 2026, but Phase 1 self-assessments, NIST SP 800-171, and a current SPRS score still gate DLA awards.
CLEATUS aggregates DIBBS contract data alongside federal, state, and local opportunities, adds a searchable catalog of all 17 million DLA stock numbers, and lists the approved suppliers on every parts solicitation before you quote. Its DIBBS software screens solicitations against your rules and drafts batch quote files that you review and upload.

What Is DIBBS?

DIBBS — the DLA Internet Bid Board System — is a web-based application operated by the Defense Logistics Agency that allows vendors to search for, view, and submit secure quotes on DLA solicitations. It's the primary portal through which DLA posts Requests for Quotations (RFQs), Requests for Proposals (RFPs), Invitations for Bid (IFBs), and contract award information.

If you sell physical products to the military — spare parts, fasteners, electronics components, medical supplies, textiles, construction materials, fuel, food — DIBBS is where the majority of those solicitations live.

Why DLA Matters

The Defense Logistics Agency is, in effect, the supply chain backbone of the entire U.S. military. To put its scale in context:

$55.4 billion in obligations in FY2025, up from $52.6 billion in FY2024 — enough to rank in the Fortune 350
$51.8 billion in revenue from its customer base in FY2025
5 million+ distinct items managed across nine supply chains
100,000+ requisitions processed daily
10,000+ contract actions per day, roughly 10,500 awards a day in FY2025
8,500+ industrial base suppliers actively supporting DLA (FY2024, the first increase since 2016)
Operations in 48 states and 28 countries

DLA supplies nearly 100% of the military's consumable items, 100% of its bulk fuel, and more than 85% of its spare parts. It serves all six military branches plus 40 federal agencies, 50 state agencies, 300 local entities, and 122 international partners.

For contractors selling products rather than services, DLA is often the single largest buyer in the federal government.

What You Can Find on DIBBS

DIBBS provides access to approximately 85% of all DLA solicitations. The types of opportunities you'll find include:

Requests for Quotation (RFQs) — The most common solicitation type on DIBBS. These are typically for supply items where DLA needs vendors to quote pricing and delivery terms. Many RFQs are automated and follow a streamlined evaluation process focused primarily on price and delivery.

Requests for Proposal (RFPs) — Used for more complex procurements where DLA evaluates technical approach, past performance, and other factors beyond price alone.

Invitations for Bid (IFBs) — Formal sealed bid solicitations where the lowest responsive, responsible bidder wins.

Award Data — DIBBS also publishes contract award information, allowing vendors to see who won specific solicitations and at what price — useful for competitive analysis and pricing strategy.

What DLA Buys

DLA's procurement spans six major subordinate commands, each focused on a specific supply chain:

DLA Command	Location	What They Buy
DLA Aviation	Richmond, VA	Aircraft parts, engines, avionics components
DLA Land and Maritime	Columbus, OH	Ship parts, vehicle components, electronics, industrial hardware
DLA Troop Support	Philadelphia, PA	Food, clothing, textiles, medical supplies, construction materials
DLA Energy	Fort Belvoir, VA	Fuel, petroleum products, alternative energy
DLA Disposition Services	Battle Creek, MI	Surplus property, reutilization, recycling
DLA Distribution	New Cumberland, PA	Warehousing, distribution, and logistics services

Approved Sources: The Rule That Decides Whether You Can Quote

Price is not the first filter on a DLA parts solicitation. Source approval is.

Every stock number DLA buys carries a list of approved sources: the CAGE codes DLA records as cleared to supply that item, each tied to its own manufacturer part number. On a source-controlled item, that list is the entire competition. If your CAGE is not on it, DLA will not evaluate your quote no matter what number you put on it.

What governs this is the Acquisition Method Suffix Code (AMSC) carried on the solicitation. The AMSC says whether the government holds a complete technical data package for the item or has to go back to a controlled source.

Status	What it means	What to do
Openly competable	The government holds full technical data rights, so any capable supplier may quote. The approved-source list is a record of who has supplied the part before, not a gate.	Quote it. Read the source list as competitive intelligence: who the incumbents are and what DLA has paid them.
Approved source only	The design is controlled. DLA will not accept a quote from a CAGE outside the listed sources.	Skip it unless your CAGE is listed. If the volume justifies it, file a Source Approval Request instead of a quote.
Sole source	A restricted part with exactly one approved CAGE. The incumbent holds the item outright and no price will move it.	Treat it as closed for this buy. These are the highest-value SAR targets when you can genuinely build the part.
No AMSC published	The code was never recorded. This is not the same as a restricted part.	Check technical data availability and ask the buyer before you invest quote time.

The numbers show how often this decides the outcome. Of the parts named on open DIBBS solicitations in September 2026, about 72% are restricted to approved sources and only about 24% are openly competable. On roughly a quarter of them, DLA lists exactly one approved supplier and will not take a quote from anybody else. That is a position no price can dislodge, sitting on a quarter of the board.

That is why "a solicitation showed up in my Federal Supply Class" is a weak signal on DIBBS. The strong signal is a part in your supply class that is openly competable, or one where your CAGE is already approved. Everything else is either a Source Approval Request project or a wasted quote.

The DIBBS Experience: What Contractors Actually Deal With

Let's be direct about what using DIBBS is actually like in 2026 — because understanding the friction is important context for why contractors are moving to AI-powered alternatives.

Code-based searching. DIBBS is designed for users who already know the National Stock Number (NSN), Federal Supply Class (FSC), or CAGE code for the items they want to supply. If you're a new entrant who manufactures a product but doesn't know its 13-digit NSN, the search experience is significantly harder. Text-based searching exists but is treated as secondary functionality.

Mandatory 60-day password resets. Defense Department security policy requires password changes every 60 days, and DIBBS emails you 30 and 10 days out. Combined with a 15-character complexity rule and an account that locks after three failed attempts, this trips up vendors who don't log in often. Unused accounts get locked or terminated too, so sign in monthly whether or not you are quoting.

No intelligent matching. DIBBS shows you everything — or nothing. There's no scoring, no fit assessment, no way to automatically surface the solicitations that match your capabilities. You either know exactly what code to search, or you're scrolling through thousands of records manually.

Limited competitive context. While DIBBS publishes award data, it doesn't connect the dots between awards, incumbents, re-compete timing, and your competitive position. That analysis has always been left to the contractor.

Source-approval status is buried. The one fact that decides whether your quote is even eligible, whether the part is openly competable or restricted to approved sources, is not a field you can search or filter on. Plenty of vendors find out only after they lose.

cFolders complexity. To access technical drawings and specifications for many solicitations, vendors need to separately register for cFolders (Collaboration Folders) and, in some cases, obtain JCP (Joint Certification Program) approval for export-controlled technical data. This adds another registration layer and another system to manage.

The core problem: DIBBS is a transaction system, not an intelligence system. It was designed to post solicitations and receive quotes — not to help vendors decide which opportunities to pursue or how to compete more effectively.

How to Register for DIBBS

Registration is straightforward but sequential. You need to complete each step before moving to the next:

Step 1: Register in SAM.gov. You need an active SAM.gov registration with a valid UEI (Unique Entity ID) and CAGE code before you can register for DIBBS. If you're not already registered, start at SAM.gov.

Step 2: Create your DIBBS account. Visit the DIBBS website and use the Vendor Registration link. You'll enter your CAGE code, and DIBBS will pull your information from SAM.gov. The first person to register under your CAGE code becomes the "Super User" — the account administrator who can add and manage other users.

Step 3: Register for cFolders. If you need access to technical drawings and specifications (most supply item vendors will), register for cFolders through the same DIBBS portal. Some items with export-controlled technical data also require JCP approval.

Step 4: Set up email notifications. DIBBS allows you to subscribe to solicitation notifications by Federal Supply Class. Configure these to receive alerts for the product categories you supply.

Registration tip: All DIBBS, cFolders, and JCP registrations are free. Third-party firms may offer to handle these registrations for a fee, but the process is straightforward enough to do yourself. Your local APEX Accelerator (formerly PTAC) can also provide free assistance.

CMMC on DLA Solicitations: What Changed in July 2026

Cybersecurity requirements started landing on DLA solicitations in late 2025, when CMMC Phase 1 took effect, particularly on buys involving Controlled Unclassified Information (CUI) or export-controlled technical data.

Then it stopped. On July 13, 2026, the Department of War (formerly the Department of Defense) suspended CMMC Phase 2 along with the implementation milestones behind it, and stood up a CMMC Reform Task Force to review the whole program. If you are reading guidance that tells you to book a third-party assessment before November 10, 2026, that deadline no longer exists. Here is where it stands as of September 2026:

Suspended	Still binding on DLA awards
Phase 2 third-party (C3PAO) Level 2 certification as a condition of award	Phase 1 self-assessment requirements, in force since November 10, 2025
The November 10, 2026 Phase 2 start date itself	NIST SP 800-171 Rev 2, enforced through self-assessments and select government-led assessments
Pending Phase 3 and Phase 4 milestones	DFARS 252.204-7012: safeguarding covered defense information and 72-hour incident reporting
	DFARS 252.204-7019/-7020: a current self-assessment score posted in SPRS
	CMMC clauses already in contracts you hold, until a contracting officer modifies them

Two points matter for DLA vendors specifically. The clause was not repealed: DFARS 252.204-7021 is still on the books, and contracting officers still check SPRS before award, so a missing or stale NIST SP 800-171 score can cost you a DLA award with no CMMC involved at all. And commercial off-the-shelf items and micro-purchases sat outside CMMC before the suspension and still do, which covers a large share of what DLA buys through DIBBS.

The Reform Task Force was due to deliver findings to the Department of War Chief Information Officer around September 13, 2026, and officials pointedly declined to rule out ending the program. Until a decision lands, build to the 110 NIST SP 800-171 controls and keep your SPRS score current; that work holds its value under every outcome on the table. We covered the suspension in full in CMMC Phase 2 Suspended.

Small Business Opportunities on DIBBS

DLA has historically been one of the more accessible agencies for small businesses. The agency actively supports small business participation, and its supplier count grew past 8,500 in FY2024, the first increase since 2016.

Why DLA Works for Small Businesses

Volume-based entry. Unlike large services contracts that require extensive past performance, many DLA supply contracts are straightforward product buys where price, quality, and delivery speed are the primary evaluation factors. This creates lower barriers to entry for manufacturers and distributors.

Set-aside availability. DLA uses small business set-asides across its solicitation portfolio, including Total Small Business, 8(a), SDVOSB, WOSB, and HUBZone designations.

Alternate offers. DLA's Alternate Offer and Source Approval Request (SAR) process allows vendors to propose themselves as approved sources for items they can manufacture — even when they're not currently listed. This is a legitimate path to get on DLA's approved source list for specific NSNs. Target the parts where the approved-source list is short and the buy volume is real; a sole-source NSN in your supply class is the highest-value SAR you can file.

Long-term contract vehicles. DLA awards multi-year IDIQ contracts that create recurring revenue streams. Once you're performing on a DLA contract, that past performance becomes a building block for future bids.

Small Business Playbook for DIBBS

Start with what you make. Identify the NSNs, FSCs, and product categories that align with your manufacturing or distribution capabilities. If you know the part but not its stock number, search by manufacturer part number or item name in the free NSN directory.
Use the "Low-Hanging Fruit" strategy. Look for solicitations that have gone unawarded 30+ days past their quote due date — these often have limited competition and represent real opportunities.
Track your win/loss data. DLA award data on DIBBS reveals winning prices. Over time, this data helps you refine your pricing strategy and identify which product categories offer the best margins.
Engage DLA Small Business. Each DLA command has small business specialists who can help you understand requirements and navigate the procurement process. DLA Land and Maritime also hosts free TKO (Training, Knowledge, Opportunities) workshops.
Consider subcontracting first. Large DLA prime contractors need component suppliers. Positioning your products within an established prime's supply chain can build past performance and revenue simultaneously.

Why DIBBS Alone Isn't Enough

DIBBS does what it was designed to do: post solicitations and accept quotes for DLA supply items. But it was never designed to be a market intelligence platform or a capture management tool.

Here's what DIBBS doesn't give you:

Capability	DIBBS	CLEATUS
Solicitation search	Code-based (NSN, FSC, CAGE)	AI-matched to your company profile
Opportunity scoring	None	Automated fit scoring against your capabilities
Who can quote the part	Not surfaced; buried in the technical data	Approved suppliers listed on the solicitation, with sole-source flags
Parts catalog	One stock number at a time, if you already know it	All 17 million DLA stock numbers, searchable by part number or item name
Competitor part coverage	None	Every NSN a CAGE is approved for, with sole-source and open counts
Competitive intelligence	Raw award data, manual analysis	Incumbent tracking, pricing trends, competitor positioning
Cross-agency discovery	DLA only	Federal + state + local + education (50,000+ sources)
Solicitation analysis	Manual document review	AI-powered requirement extraction and compliance mapping
Bid/no-bid support	None	Data-backed PWin scoring with competitive landscape
Proposal support	None	AI Proposal Suite with compliance matrices and past performance matching
Monitoring	Email alerts by FSC	Continuous AI monitoring with real-time scoring

The pattern here mirrors what we saw with FPDS: government systems are data repositories, not strategy tools. Contractors who treat them as their primary workflow are doing the analysis themselves — in spreadsheets, with manual effort, at the cost of time and opportunities missed.

How CLEATUS Surfaces DIBBS Contracts Automatically

CLEATUS aggregates DLA solicitation data alongside opportunities from SAM.gov, state portals, local procurement boards, and education institutions — over 50,000 sources in total. This means DIBBS contracts appear in the same pipeline as every other opportunity, scored against your company profile.

No more code hunting. Instead of searching DIBBS by NSN or FSC, CLEATUS matches DLA solicitations to your capabilities automatically. Define your profile once — products, certifications, NAICS codes, geographic preferences — and relevant DIBBS opportunities surface in your daily feed.

Search the whole DLA catalog, not one stock number at a time

CLEATUS carries all 17 million stock numbers in DLA's parts catalog as NSN Lookup, part of Market Intelligence. Search by stock number, manufacturer part number, or plain item name, and the part page shows what the item is, its DoD standard price and unit of issue, the CAGE codes DLA approves to supply it, the organizations that manage it, and every DIBBS solicitation and award that has named it. A dashed NSN, a compact one, and a bare NIIN all resolve to the same part, so it does not matter how the number was written on the drawing you were handed. Filter by supply class, supply group, acquisition method code, or a single CAGE. The directory is public at cleat.ai/government/nsn, no account required.

See the approved suppliers before you write the quote

Open a DIBBS solicitation that carries a stock number and Approved Suppliers sits on the General Information tab: every company DLA lists as an approved source for that part, with its CAGE code, location, and the part numbers it is approved under. The page states plainly whether the item is "Approved source only" or "Openly competable," and flags the parts where DLA lists exactly one company. Any supplier with a CLEATUS profile links straight through to its award history, so the incumbent's pricing is one click from the solicitation. The eligibility check that used to mean digging through technical data now happens before you spend a minute on the quote.

See every part a competitor is locked into

Any contractor with a DLA parts catalogue carries an Approved Supplier tab covering every stock number that company's CAGE is an approved source for: how many parts in total, how many they are the sole approved source for, how many are openly competable, and how many are restricted. Click a stat card or a slice of the competition posture chart to drill into exactly those parts, then filter by competition status, AMSC, or Federal Supply Class, or search by NSN, nomenclature, or part number. It is the fastest way to size up an incumbent before you commit to a Source Approval Request, and to find the supply classes where a competitor has no lock at all. Start from any company in the contractor directory.

Keep DIBBS volume where you want it

DIBBS posts thousands of parts solicitations a day, which is exactly why so many contractors stop opening the feed. In CLEATUS, DIBBS is its own contract source, separate from SAM.gov federal: switch it on if you quote parts, off if you don't, and your other federal opportunities are untouched either way. In Contract Search, DIBBS solicitations carry their own badge, so you know what kind of opportunity you are looking at before you open it.

Competitive context built in

CLEATUS connects DLA award data with solicitation information to show you who's winning contracts in your space, what they're charging, and when re-competes are coming. The competitive intelligence that takes hours to extract from DIBBS manually is delivered automatically.

One pipeline, every source

If you sell products to DLA but also pursue services contracts on SAM.gov or supply to state agencies, you don't need separate workflows for each. CLEATUS brings them all into a single, prioritized pipeline.

From research to quote preparation. DIBBS software combines solicitation analysis, approved-source research, and batch quote drafting from available award history. You review the quote fields and upload the file to DIBBS yourself.

"CLEATUS transformed our entire operation. We tripled our output with the same team and eliminated days of manual work."

– John Garnish, Business Development Lead, D2 Government Solutions
