For Corporations (Inc, Corp): Ensure you are using the name from Line 1 of your SS-4 form, not your "Doing Business As" (DBA) name.

What if I don't have my EIN / SS-4 Letter?

If you cannot locate your original SS-4 letter, or if the combinations above still fail, you may need to request a Letter 147C (Verification of Non-Filing) from the IRS to confirm how your record is stored.

  • Call the IRS Business & Specialty Tax Line at 1-800-829-4933.

  • Request a "Letter 147C" to verify your EIN.

  • Upload a copy of this letter in your Frame Dashboard once received.
