SAM.gov Troubleshooting Guide: Fix Login, Registration & Validation Errors
Complete troubleshooting guide for SAM.gov issues. Fix common login problems, registration errors, entity validation failures, renewal issues, and account lockouts with step-by-step solutions.
Quick Answer
Most SAM.gov issues fall into four categories: Login.gov account problems (password reset, MFA issues), entity validation failures (IRS mismatch), registration errors (incomplete data), or permission issues (wrong user roles). Contact the Federal Service Desk at 866-606-8220 for issues you cannot resolve through self-service. Average resolution time is 3-10 business days.
Login & Account Issues
SAM.gov uses Login.gov for authentication. Most login problems originate with your Login.gov account, not SAM.gov directly.
Account Locked Out
Cause: Too many failed login attempts or suspicious activity detected.
Solution:
- 1. Wait 24 hours for automatic unlock, OR
- 2. Go to Login.gov and click "Forgot password"
- 3. Complete identity verification if prompted
- 4. Create new password and re-enable MFA
MFA/2FA Not Working
Cause: Authentication app out of sync, phone number changed, or backup codes lost.
Solution:
- 1. Sync your authentication app's time settings
- 2. Use backup codes if available
- 3. If phone changed, contact Login.gov support
- 4. May need to delete and recreate Login.gov account
Not Receiving Verification Emails
Cause: Spam filters, typo in email, or corporate email blocking.
Solution:
- 1. Check spam/junk folders for @login.gov and @sam.gov
- 2. Whitelist these domains in your email
- 3. Try a personal email if corporate blocks government emails
- 4. Verify correct email spelling in Login.gov profile
Can Log In But Can't Access Entity
Cause: Your Login.gov account is not linked to the SAM.gov entity, or you lack the proper role.
Solution:
- 1. Check if you're logged in with the correct Login.gov account
- 2. Ask the Entity Administrator to add your role
- 3. If you are the admin and lost access, contact FSD
- 4. May need to submit Entity Administrator role request
Registration Errors
Incomplete Registration
Registration stuck in "Work in Progress" status.
- • Complete all required fields (marked with *)
- • Save each section before moving on
- • Check Core Data, Assertions, Reps & Certs
- • Submit after all sections show complete
CAGE Code Issues
CAGE code not assigned or showing errors.
- • CAGE auto-assigns for new registrations
- • International entities need NCAGE first

Registration Takes Time
New registrations take 7-10 business days to process after submission. Renewals take 3-5 days. Do not create duplicate registrations—this creates bigger problems. Track your existing registration status in the SAM.gov workspace.
Entity Validation Problems
SAM.gov validates your business information against IRS records. Validation failures prevent registration completion.
TIN Validation Failed
Your Tax Identification Number does not match IRS records.
Check These Items:
- • TIN entered correctly (no typos)
- • Legal name matches IRS exactly
- • Using EIN, not ITIN
- • EIN is at least 2 weeks old
Resolution Steps:
- • Get IRS CP 575 letter
- • Compare exact spelling/punctuation
- • Update SAM.gov to match IRS
- • Resubmit for validation
Legal Name Mismatch
Business name in SAM.gov does not match IRS records.
- • Use legal entity name, not DBA (trade name)
- • Match abbreviations exactly (Inc. vs Incorporated)
- • Include or exclude punctuation as IRS shows
- • Entity suffix must match (LLC, L.L.C., etc.)
Manual Validation Request
If automated validation repeatedly fails despite correct information:
- 1Contact Federal Service Desk at 866-606-8220
- 2Request manual TIN validation
- 3Provide IRS CP 575 letter or other IRS documentation
- 4Allow 10-15 business days for manual review
Renewal & Expiration Issues

Frequently Asked Questions
Do I have to pay for SAM.gov registration?
No, SAM.gov registration is completely free. If any company asks for payment to register you in SAM.gov, it is a scam. The government does not charge for registration or renewal.
Why does registration take so long?
SAM.gov validates your information against IRS records, CAGE code systems, and other government databases. New registrations take 7-10 business days; renewals take 3-5 days. Incomplete submissions or validation failures extend this timeline.
I can't find my entity in SAM.gov search. Why?
Your entity only appears in public search after registration is fully processed and status is "Active." Work in progress registrations are not publicly visible. Also check that your entity is not set to "Opt Out of Public Display."
What if someone else registered my company without permission?
Contact the Federal Service Desk immediately. You'll need to provide proof of ownership/authority over the business (articles of incorporation, notarized letter, etc.). FSD can investigate and transfer control to the rightful owner.
Can I use SAM.gov on mobile devices?
While SAM.gov is accessible on mobile browsers, the full registration and update process is best completed on a desktop computer. Some features may not work properly on mobile devices due to the complex forms involved.
