Please refer to your EIN Letter (SS-4 or 147C Letter (the letter you received when you were assigned your EIN).
For Example:
Legal Business Name:
DELOREAN LLC
EIN (Employer Identification Number):

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.
