Apostille of an IRS EIN letter
The EIN confirmation letter, such as Form CP 575 or a 147C letter, is issued by the Internal Revenue Service (IRS), a U.S. federal agency. Because it is a federal document, it follows its own authentication route through the Department of State's Office of Authentications, and it is not sent to a state Secretary of State. Having it notarized by a local notary public does not substitute for this process; that is a common misconception that can delay your case.

What is an apostilled EIN letter used for?
The EIN (Employer Identification Number) identifies a company with the IRS. An apostilled or authenticated EIN letter is often requested to open a branch abroad, for due diligence processes, international bids, or banking and corporate procedures outside the United States.
Key points about your EIN letter
The EIN letter is a federal document issued by the IRS. It is not apostilled like a state document, and it is not notarized by a local notary public; it follows the Department of State's authentication route.
It's a federal document, not a state one
It is issued by the IRS, a federal agency; that is why it is not sent to any state's Secretary of State.
Local notarization does not substitute for federal authentication
Having the letter notarized by a notary public is not a valid step for this process; federal authentication is issued by the Department of State's Office of Authentications.
