EIN Not Found Error During A2P Registration - How to Fix
Fix the 'EIN not found' error during A2P SMS registration. Verify your EIN format and IRS registration status.
Quick Answer: The 'EIN not found' error means the tax ID you entered doesn't match IRS records. Double-check your EIN on official tax documents, ensure it's 9 digits with no dashes, and verify your business is properly registered with the IRS.
What You'll Learn
This guide explains why EIN verification fails and how to find and enter your correct EIN for A2P registration.
Common Causes
- Typo in the EIN: Incorrect digit or transposed numbers
- Using SSN instead of EIN: Personal tax ID won't work for business registration
- New business: IRS database hasn't updated yet (can take 2-4 weeks after filing)
- Format issues: Including dashes or spaces when entering
- Wrong EIN: Using an EIN from a different business entity
How to Find Your Correct EIN
- IRS confirmation letter: The CP 575 notice you received when assigned the EIN
- Tax returns: Your business tax returns show your EIN
- Bank statements: Business bank account statements often show EIN
- IRS online: Call IRS at 1-800-829-4933 or use their online verification
- State filings: Your state business registration may show the EIN
Entering EIN Correctly
- Find your EIN from official documentation
- Enter all 9 digits without dashes or spaces
- Correct format: 123456789
- Incorrect format: 12-3456789 or 123-45-6789
- Triple-check for typos before submitting
If Your Business Is New
If you recently applied for your EIN:
- Wait 2-4 weeks after receiving your EIN for IRS records to fully update
- The IRS database used for verification may lag behind
- Your EIN is valid even if verification temporarily fails
- Try again after waiting, or contact support for manual verification
