DBE vs MBE vs WBE vs SBE: how state certification programs differ in what they issue
Published May 25, 2026 · ~7 minute read
"DBE certification" is often discussed as a single credential, but it's actually a family. The federal Disadvantaged Business Enterprise program (DBE) is the largest and most widely recognized, but many state certifying agencies issue additional certifications alongside it: Minority Business Enterprise (MBE), Women Business Enterprise (WBE), Small Business Enterprise (SBE), Airport Concessionaire DBE (ACDBE), and various federal Small Business Administration tracks (8(a), HUBZone, WOSB, EDWOSB, VOSB, SDVOSB). For a firm trying to decide which certification to pursue, the choice often depends on what their state's program actually offers.
We analyzed all 216,689 certifications in the DBE Source database that carry a state-tagged certifying agency. For each state, we computed the share of certifications issued in each type. The result is a clear picture of which state programs are essentially DBE-only and which run diversified multi-track operations.
Composition by state
The chart below shows each state's certification mix as a stacked bar normalized to 100%. The top row (dashed) is the national baseline for reference. Sort by "% DBE descending" to see pure-DBE states at the top and diverse-mix states at the bottom.
The most diversified state programs
Virginia — the most cert-diverse state
Only 8.7% of Virginia's certifications are federal DBE. The rest break down to 42.3% SBE (Virginia's SWaM program issues a large volume of small-business certifications), 21.3% MBE, 18.4% WBE, 3.3% veteran-owned, and small amounts in other categories. The Virginia Department of Small Business and Supplier Diversity runs all of these in parallel with the state DOT's federal DBE certification. A Virginia firm has more parallel certification paths than a firm in nearly any other state.
Maryland — the largest MBE program in the country by share
Maryland is 49% DBE, 23.2% MBE (highest national share), and 25.2% SBE. The Maryland Department of Transportation's MBE program is a major state- level program parallel to the federal DBE channel, and the volume reflects that: 8,342 MBE certifications in our database, more than any other state. Maryland doesn't issue a separate WBE designation under MDOT in the same way (the SBE program effectively covers small-business and women-owned tracks).
Oregon — diverse multi-track program
Oregon's breakdown: 12.8% DBE, 34.9% SBE, 27.9% WBE, 20.0% MBE. The Certification Office for Business Inclusion and Diversity (COBID) administers state DBE, MBE, WBE, and ESB (Emerging Small Business) certifications. Of any large-volume state, Oregon has the highest WBE share (27.9%) — a state-level women-business program with substantial issuance.
District of Columbia
DC issues 44.4% DBE, 33.0% SBE, 19.5% MBE. DC's Department of Small and Local Business Development (DSLBD) administers a Certified Business Enterprise (CBE) program that includes small business (SBE), local business (LBE), disadvantaged business (DBE), and resident-owned business (ROB) sub- certifications.
North Carolina — the only state with substantial HUB issuance
NC's breakdown: 51.3% DBE, 19.8% MBE, 8.8% ACDBE, 8.2% HUB (Historically Underutilized Business), 7.4% WBE, 3.2% SBE. NC's HUB program (administered by the NC Office for Historically Underutilized Businesses) is the only one of its kind with meaningful volume in our database. Texas also has a HUB program by the same name, but those certifications do not appear in our database under that label.
Pure-DBE states
At the other end of the spectrum, a substantial group of states issue essentially only federal DBE certifications, plus a small amount of ACDBE for states with airports participating in the federal airport program. These jurisdictions don't have meaningful parallel state MBE/WBE/SBE programs in our data:
- Wyoming: 100% DBE (n=36) — no state cert programs other than the federal DBE.
- Delaware (96.3% DBE), Mississippi (96.4%), Idaho (96.6%), Kansas (95.6%), Alaska (94.7%): essentially DBE-only, with a few percent ACDBE for airport concessionaires.
- Connecticut (95.9% DBE), Massachusetts (94.6%), New Hampshire (98.4%): New England jurisdictions that are heavily DBE-only despite the regional contracting cluster we mapped in our cluster analysis.
- Pennsylvania (93.5%), Louisiana (92.6%), Alabama (92.4%), Arkansas (92.6%), New Mexico (91.5%): similar DBE-heavy structure.
For a firm headquartered in any of these states, the certification path is much simpler — there's really only one program to apply to. The trade-off is fewer ways to compete: a firm in Maryland with both DBE and MBE certs has access to procurement set-asides that aren't available to a Wyoming firm holding only a DBE.

What this means in practice
For a DBE-eligible firm picking which certification to pursue first, the practical implication is geography- dependent. In a diversified state (Virginia, Maryland, Oregon, DC, North Carolina), the firm should consider holding multiple certifications simultaneously, since each state-specific program may have separate set-asides and goal requirements. In a pure-DBE state, the federal DBE is essentially the only path — but the firm may still find value applying to neighboring states' programs through reciprocity (see our regional cluster analysis).
For a prime contractor working DBE goal requirements, the certification-type mix matters because federal DBE goals and state MBE goals operate under different rules. A Maryland MBE-certified subcontractor counts toward Maryland MDOT MBE goal requirements on state-funded projects, but doesn't automatically count toward federal DBE goals on FHWA-funded projects unless they also hold the DBE cert. Most firms with serious public-sector business pursue both in states where both are available.
Methodology
- Data source
- DBE Source database, May 2026 snapshot. 217,546 certification records with a state-tagged certifying agency (50 states + DC); 216,689 records remain after filtering blank certification_type values. Records tagged as "National" (SBA 8(a), HUBZone, etc. without a state issuer) are excluded.
- Cert-type bucketing
- Several certification_type values in the database represent multi-credential firms (e.g.,
"VOSB, SDVOSB"or"WOSB, EDWOSB"). We split comma-separated combinations and count each component separately, then bucket into 11 display categories: DBE, ACDBE, MBE, WBE, SBE (including ESBE, ESB, SBC), Veteran-owned (VOSB + SDVOSB), Women-owned (SBA) (WOSB + EDWOSB + pending variants), HUBZone, 8(a), HUB (NC), and Other. The Other bucket catches state-specific labels and edge cases (~0.9% of total). - What this measures and what it doesn't
- The chart reflects the certification mix actually issued by certifying agencies in each state, as captured in our database. It does not measure firm demand (some states may have ample MBE-eligible firms that don't pursue certification because the program isn't available locally). Texas's HUB program is not visible in this data despite being substantial, which suggests either an ingestion gap or a categorization difference — the absence here is data quality, not a true zero.
Frequently asked questions
What's the difference between DBE and MBE certification?
DBE (Disadvantaged Business Enterprise) is a federal program administered by the US Department of Transportation. It applies to federally-assisted transportation contracts and is administered locally by state DOTs under uniform federal rules (49 CFR Part 26). MBE (Minority Business Enterprise) is a state-level designation; rules and eligibility vary by state. A firm can hold both DBE and MBE certifications simultaneously, with different uses: DBE for federal- aid contracts, MBE for state procurement set-asides. Maryland leads the country in MBE issuance, with 23.2% of all Maryland certifications being MBE.
Which state issues the most diverse mix of certifications?
Virginia has the most diverse certification mix: only 8.7% of state-issued certifications are federal DBE. The remainder is split across SBE (42.3%), MBE (21.3%), WBE (18.4%), and smaller veteran-owned and federal tracks. The Virginia Department of Small Business and Supplier Diversity administers the SWaM (Small, Women, and Minority) program alongside the state DOT's federal DBE certification.
Which states issue mostly just federal DBE certs?
States where 95%+ of state-issued certifications are federal DBE include Wyoming (100%), New Hampshire (98.4%), Nebraska (99.4%), South Dakota (97.5%), Idaho (96.6%), Mississippi (96.4%), Delaware (96.3%), Connecticut (95.9%), and Kansas (95.6%). These states either don't run parallel state MBE/WBE/SBE programs or run them at very low volume.
Why is Vermont's WBE share so high (48.2%)?
Vermont has a small but active state women-business certification program. With only 301 total Vermont certifications in our database, the WBE share is high because the absolute volume of any single program is small. The 145 WBE certs in Vermont put it at the top of the WBE-share ranking, but in absolute terms Maryland (8,342 MBE) and Oregon (1,583 WBE) issue far more women/minority-focused certifications.
What about Texas's HUB program?
Texas operates a Historically Underutilized Business (HUB) certification program through the Texas Comptroller's office. These certifications are substantial in number but do not appear in our database under the "HUB" label — they may be categorized differently or ingested from a different source. Our data shows 682 HUB-labeled certifications, essentially all in North Carolina (whose Office for Historically Underutilized Businesses uses the same acronym). This is a data-quality gap on our side, not evidence of low Texas HUB activity.
Caveats
The mix reflects what our database captures, which is a function of which certifying agencies' directories we have ingested. If a state runs a state-level MBE program whose directory we haven't fully ingested, that state's MBE share will look artificially low. The Texas HUB gap noted above is one example. Treat very-low-mix states as "ingested as DBE-heavy in our data" rather than "definitely has only DBE programs."
Comma-separated certification_type values (e.g., "VOSB, SDVOSB") are split and counted per component, so a single record can contribute to multiple type buckets. State percentages sum to 100% within each row because we're computing shares of the expanded type-component total, not of the row count.
Counts here are of certifications, not firms. A single company holding both a DBE and an MBE cert in Maryland contributes to both buckets. For a firm-count perspective, see our state-level density analysis.
