Eligibility checklist
- Small business by SBA size standard
- At least 51% owned and controlled by socially and economically disadvantaged individuals
- Same socioeconomic and net-worth thresholds as 8(a)
- Self-represented in SAM.gov — no SBA certification required (8(a) firms are automatically SDB)
How to get certified
- Confirm size and disadvantage criteria. Use 8(a) criteria as your reference — they're essentially identical.
- Self-represent in SAM.gov. Update entity profile to claim SDB status.
- Pursue 8(a) for set-aside power. If you qualify, the certified 8(a) program adds sole-source eligibility.

FAQ
Is SDB the same as 8(a)?
Similar criteria, different mechanics. 8(a) requires SBA certification and unlocks sole-source contracts. SDB is self-represented in SAM.gov and used by primes/agencies to track 5% government-wide subcontracting goal achievement.
Why claim SDB if there's no set-aside?
Primes need SDB subcontractors to meet their 5% goal on large contracts. Self-representing as SDB makes you findable in SAM.gov searches by primes hunting for SDB partners.
