How to Request an Identity Theft Block: Complete Requirements

The identity theft block under section 605B of the Fair Credit Reporting Act, 15 U.S.C. § 1681c-2, is the fastest remedy available to a fraud victim. A complete request obligates the bureau to block the information, generally within four business days, without waiting on the furnisher.

The word doing the work there is complete. A request missing one of four elements can be declined on that basis alone, no matter how clearly fraudulent the account is. Here is what each element means in practice.

Why Completeness Decides It

An ordinary dispute starts an investigation. The bureau forwards it to the company that reported the account, that company checks its own records, and the item usually comes back verified.

A block skips that entirely. The bureau removes the information first and notifies the furnisher afterward. That is a serious obligation to impose on a short deadline, and the four requirements are the statutory price of imposing it. Treat them as a checklist rather than a formality.

1. Proof of Your Identity

The bureau has to confirm you are who you say you are before acting on your file. Expect to provide:

A copy of a government issued photo ID, such as a driver's license, state ID, or passport
Proof of your current address, such as a utility bill or bank statement
Your Social Security number

Send legible copies. A dark photocopy of a license is a reason to come back to you with questions, and every round trip restarts the clock.

2. An Identity Theft Report

Include a copy of an identity theft report. An FTC report from IdentityTheft.gov qualifies and is free to generate, usually in under twenty minutes. A valid police report about the theft also works.

This document is what distinguishes a block request from a dispute. Without it there is no block right to invoke.

3. Identification of the Fraudulent Information

Name each item. For every account you want blocked, give:

The furnisher's name exactly as it appears on the report
The account number as the report shows it
The date opened and the balance shown
The bureau the item appears on

A request to block everything fraudulent on the file is not identification of specific information. It is the single most common defect, and it is entirely avoidable: work from the report in front of you and copy the details across.

4. A Statement of Non-Authorization

State plainly that the information does not relate to any transaction you made or authorized.

This is a statutory element, not a courtesy. It is also the one with teeth attached, because a material misrepresentation here is a ground for the bureau to decline the block or rescind one already in place. Which leads to the discipline that matters most: only include accounts that are genuinely not yours. An account you co-signed is not identity theft. An account a family member opened with your permission is not identity theft. Including one weak item gives the bureau an argument against the entire request.

Putting the Request Together

A complete package contains:

Your name, current address, date of birth, and Social Security number
A clear statement that you are requesting a block under FCRA section 605B, 15 U.S.C. § 1681c-2
Copies of your ID and proof of address
A copy of your identity theft report
An itemised list of each account to block, with the identifying details above
Your statement that you did not make or authorize the transactions
Your signature and the date

Send it to each bureau where the fraudulent item appears. Unlike a fraud alert, a block request does not propagate; a block at Experian does nothing about the same account at TransUnion.

Sending It and Tracking It

Certified mail, return receipt requested, and keep the green card
Calendar four business days from the delivery date, not from the date you mailed it
Pull the report after the deadline and confirm the items are actually gone
Keep the before and after reports together. They are dated proof of what changed and when

If the Deadline Passes

A bureau that treats a complete block request as an ordinary dispute, sends it out for verification, and leaves the item on your file has not done what the statute requires. Neither has one that blocks the item and then lets it reappear a month later when the furnisher sends its next monthly file.

Both are provable, and both are provable only from the record. The request, the proof of delivery, the response, and the reports from either side of the deadline are the whole case.

A Template You Can Adapt

Keep it short and structured. A block request is a checklist, not an argument, and the bureau is matching your letter against four statutory elements.

Then identify yourself with your full legal name, current address, date of birth, and Social Security number.

Then list the items, one per line, each with the furnisher name as the report shows it, the account number as the report shows it, the date opened, and the balance reported.

Then the statement, in your own words but unambiguous: that the listed information does not relate to any transaction you made or authorized.

Then the enclosures: a copy of your identity theft report, a copy of your government issued ID, and a copy of your proof of address.

Close by asking the bureau to confirm the block in writing, sign it, and date it.

The Mistakes That Sink Requests

Vagueness is the first. A request to block all fraudulent accounts identifies nothing, and identification is one of the four elements.

Over inclusion is the second and it is worse, because it is not merely incomplete, it hands the bureau a reason to question everything. Including an account you co-signed, or one a relative opened with your knowledge, or a legitimate debt you would rather not pay, exposes the whole request to a material misrepresentation argument. Block only what was never yours.

Sending it unsigned, or by ordinary mail with no proof of delivery, is the third. The deadline runs from receipt, and without a green card you cannot establish when receipt happened.

Sending it to only one bureau is the fourth. The block does not propagate.

Common Questions

How do I write an identity theft block request letter?

State that you are requesting a block under 15 U.S.C. § 1681c-2, identify yourself, list each fraudulent item with the furnisher name and account number exactly as they appear on the report, include the statement that the information does not relate to any transaction you made, and enclose your identity theft report, ID, and proof of address.

Where do I send it?

To each nationwide bureau where the fraudulent item appears, at the address the bureau publishes for identity theft or FCRA correspondence. Send it certified mail with return receipt requested.

How long does the bureau have?

Four business days from receiving a complete request. The clock runs from delivery, which is why proof of delivery matters more than the date you posted it.

What if I do not have an identity theft report yet?

Get one first at IdentityTheft.gov. It is free and takes under twenty minutes. Without it there is no block right to invoke, and a request sent without one will be declined on that basis regardless of the merits.

Can a lawyer send the block request for me?

A lawyer can prepare it, and for a block request the signature question is less fraught than it is for an ordinary dispute, where bureaus have argued that a lawyer signed letter is not a dispute by the consumer. The safer practice in both cases is for you to sign and mail it yourself.
