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 JJ74ZCCVA1M7 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications including VetCert.
