How to choose

  • What market are you targeting — federal, state/local, transportation, or corporate?
  • Who recognizes the certification?
  • Are you actually eligible under the current rules?
  • What documents and renewal requirements apply?
  • Does your target buyer or agency actually use it?
Never pay SBAEX for a government certification. Apply only through the official certifying organization or its authorized process.

Before applying, use the supplier readiness checklist to organize your documents, and read how to become a corporate supplier.
