- The rookie mistakes that get registrations rejected — and the pre-flight checklist that prevents them
Who This Book Is For
Contractors who are stuck at the starting line: SAM.gov rejected you, your CAGE code isn't showing in DIBBS, or you haven't started registration because everyone you asked gave you a different answer. If 'CAGE Not Found' is the error staring at you right now, this is the book for you.

Frequently Asked Questions
If your SAM.gov data is clean, the DIBBS account itself is quick — same day. The slow part is SAM.gov activation and CAGE code issuance, which typically runs a few business days to two weeks. The guide shows you how to avoid the mismatches that stretch that into months.
Almost always a data mismatch or propagation delay: your SAM.gov registration is incomplete, under review, or your CAGE hasn't propagated to DIBBS yet. The book covers the exact check sequence — and who to escalate to if it's been more than 30 days.

Yes — SAM.gov, the UEI, your CAGE code, and DIBBS access are all free. Anyone charging you a fee to 'register you' is selling a service you can do yourself. This book exists so you can do it right the first time.
