UKHow long does SAM.gov registration take?
Plan for one to three weeks. Getting a Unique Entity ID can be quick, but entity validation and the full registration review often take several business days to a couple of weeks, so register before you need to bid.
SAM.gov registration is free but not instant. Entity validation — proving your legal business name and address — is the usual delay, and the overall review can take from a few days to a few weeks.
Start early. You do not want to discover a two-week registration delay the week a perfect opportunity closes.
