Four checks before returning an EIN document
01Preserve what actually arrived
Keep every page and the envelope or delivery details in your own secure file. Record the letter date, date received, legal entity, stated purpose, CP/LTR number if shown and any response date. Do not publish the notice or paste its identifiers into an unverified support conversation.
The IRS notice guide says to review and retain the correspondence and act by the due date when a response is requested. Verification does not pause or extend that date.
02Open IRS.gov independently
Type IRS.gov yourself and open its notice-and-letter search. Search the CP or LTR number, or the topic, rather than using a link or QR code in the questioned message. Compare the described issue with the exact entity and the EIN activity you know about.
The IRS says the CP or LTR number is in the right corner of its letter. If a number is absent, does not appear in the search or points to a different issue, record the gap. An absent search result alone is not proof of a fake. The IRS notice guide directs people with a suspicious or unlisted letter to contact the agency for instructions.
03Verify the channel, not just the logo
If the correspondence is in doubt, get contact details from an independently opened IRS page. The business telephone-assistance page identifies the Business and Specialty Tax Line and says its services cover EINs and business accounts. Use current official guidance appropriate to your situation; this page does not place a call or authenticate a representative.
The IRS scam guidance flags threats, pressure to pay immediately and odd or misspelled web links. A familiar name, seal or letter number does not resolve those warnings. Do not treat the questioned message’s own number or link as the independent check.
04Keep one controlled response
Once the request and instructions are confirmed, list the specific correction or documents requested, the verified return method and the response date. Keep copies of what you send and proof of transmission. If verification is unresolved, record the next official contact step promptly, especially when a deadline is close.
For a confirmed incomplete SS-4 request, return to the Letter 45C and problem-fax guide. This check does not create a new EIN application, decide a tax liability or replace the instructions issued for your case.
A review record you can hand to the next person
Keep the original documents in secure storage. Use these headings to explain the verification, without putting an EIN, SSN or passport in a public note. This is an editorial checklist, not an IRS form.
- Request
- Entity, delivery date, letter reference and requested action. Where is the complete original stored?
- Official lookup
- IRS.gov page, date checked and what matched the request. Mark any missing or inconsistent fact.
- Independent contact
- Official contact page used, contact date and actual outcome. “Not yet verified” is a valid status.
- Next action
- Confirmed return instructions or the next verification step, any response date and the person handling the entity’s private records.

Complete the record in your own private file. Do not send the completed record or your notice to EINForeigner.
One fictional request, two possible outcomes
The received packet
Fictional example: Cedar Notebook Example LLC receives a message headed “Letter 45C.” It names the LLC, asks for a signed SS-4, states a response date and includes a link demanding an “IRS EIN release fee.” The owner recognizes the name from a recent application.
Record first: familiar name and letter title; requested SS-4; stated date; unexplained fee and return link. None of those facts establishes who sent the message.
Outcome A: verification is unresolved
Hold the disclosure; contact the IRS independently.
The owner searches the notice type on IRS.gov but cannot confirm this request or its return channel. The record stays “unverified.” The owner does not use the supplied upload link, treats the stated date as something to resolve promptly and follows current IRS instructions for a suspected impersonation.
The IRS EIN page says an EIN is free directly from the agency. That does not establish that every tax notice is free of a balance due, or that every private preparer’s fee is fraudulent. The claimed “IRS EIN release fee” needs independent verification; it is not an established IRS charge.
Outcome B: the IRS confirms the actual request
Retain the confirmation and use the confirmed instructions.
In this alternative, an authorized person reaches the IRS through independently obtained official contact details, and the agency confirms a missing-information request and how to return the correction. The person records that outcome, prepares only the requested response and retains delivery evidence.
This outcome assumes actual confirmation. A matching letter number, a successful website search or this example cannot supply it.
