How to check or correct this record
The file sometimes leaves a certification out, and a newer one won't be in it yet. Self-reported business types are what the firm says about itself on SAM.gov; they aren't SBA certifications. This page doesn't show SBA's VetCert certification for veteran-owned firms; SBA's search below does.
Check or correct this record at the source: open its SAM.gov entry, or search UEI YZW6NRFY58N3 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert. The business can update its details in its SAM.gov registration and its certifications at certifications.sba.gov.

Brown, Inc.'s NAICS codes and may be open to it: no set-aside, or, in the codes it is registered small under, a small business set-aside or one for a status it reports about itself on SAM.gov (service-disabled veteran-owned).
