How to check or correct this record
The public file gives neither the date a certification started nor the firm's employee count. 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 HNYQBL9BL3Z6 () 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.

Open contracts in Signalink Inc's NAICS codes
496 open federal opportunities on SAM.gov use one of Signalink 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 an SBA certification SAM.gov's file lists for it (women-owned (WOSB)), or one for a status it reports about itself on SAM.gov (service-disabled veteran-owned). Here are a few, those in its primary code first, then those in Alabama, then the soonest due.
Confirm eligibility first. Signalink Inc's service-disabled veteran-owned status is self-reported on SAM.gov, and this page can't confirm an SBA certification for it, so set-asides for it may be relevant but may not be open to it: SDVOSB and VOSB set-asides need SBA VetCert certification. SBA's Small Business Search shows a firm's current certifications.
