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.
Check or correct this record at the source: open its SAM.gov entry, or search UEI Y48KFPRLWYU6 () in SAM.gov's entity search (free sign-in) and in SBA's Small Business Search (formerly DSBS), which shows SBA certifications. The business can update its details in its SAM.gov registration and its certifications at certifications.sba.gov.
NAICS codes Legionarius LLC is small under
On its SAM.gov registration, Legionarius LLC meets the SBA size standard for these industries, so it can bid on small business set-asides that use them.
Open contracts in Legionarius LLC's NAICS codes
352 open federal opportunities on SAM.gov use one of Legionarius LLC'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 (women-owned (WOSB)). Here are a few, those in its primary code first, then those in Massachusetts, then the soonest due.
Confirm eligibility first. Legionarius LLC's women-owned (WOSB) 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: WOSB and EDWOSB set-asides need SBA WOSB program certification. SBA's Small Business Search shows a firm's current certifications.
