Hi Everyone,

I’m looking for clarification regarding the authority granted under Form 8821 (Tax Information Authorization) and whether it is sufficient to request a Form 147C (EIN Verification Letter) on behalf of a client.

I have already reviewed the IRS procedures for how Form 147C can be requested, and here are the methods I found:

Ways to Request a Form 147C (EIN Verification Letter):

1. Call the IRS Business & Specialty Tax Line at 1-800-829-4933
2. Taxpayer Assistance Center (TAC) appointment
3. Mail request

Given these methods, I want to confirm:

If a tax professional is authorized via a properly completed and processed Form 8821, can they request a Form 147C on behalf of their client?

I understand that Form 8821 allows access to tax information but does not authorize representation before the IRS. Since Form 147C is simply an EIN verification letter (not a dispute or a change request), I’m trying to determine whether the IRS will provide it to a Form 8821 designee.

Has anyone here successfully requested a Form 147C using a Form 8821 authorization?
Any experiences, references, or insight would be helpful.

Thank you!
