Getting an EIN verification letter (Form 147C) is one of those “old school” administrative tasks that requires a bit of patience and a working telephone. Since there is no online portal for this, calling is indeed your only shortcut.
Here is the step-by-step process to get it done efficiently:
1. Preparation: Gather Your Information
Before dialing, ensure you have the following details in front of you. The IRS agent will not issue the letter if any of this information is missing or incorrect:
- Entity’s Legal Name: Exactly as it was registered.
- Employer Identification Number (EIN).
- Business Address: The address currently on file with the IRS.
- Your Personal Details: Your full name and your official title within the business.
- Authorization: If you aren’t the owner/officer, ensure you have a valid Power of Attorney (Form 2848) or Tax Information Authorization (Form 8821) on file.
2. The Phone Call
- Dial: 1-800-829-4933 (IRS Business & Specialty Tax Line).
- Hours: 7:00 AM – 7:00 PM local time, Monday through Friday.
- Pro Tip: Calling right when they open is usually the fastest way to avoid long hold times.
3. EIN Verification Letter Request Process
Once you reach an agent, notify them that you are requesting a Letter 147C. They will put you through a security screening to verify:
- Your identity.
- Your authorization to receive sensitive tax information for the business.
4. Choose Your Delivery Method
You have two options for receiving the letter, but one is significantly faster:
- Option A (Fastest): Fax. If you have a fax machine or a secure digital fax service, tell the agent. They can often transmit the letter to you while you are still on the line.
- Option B (Standard): Mail. If you cannot receive a fax, the IRS will mail the letter to the official address of record. Note that this can take 7–10 business days (or longer depending on the postal service).
