FCRA Section 605B — Identity Theft Block Explained

If a credit-card account, a hard inquiry, or a public record on your credit report is the result of identity theft, you do not have to file a standard §611 reinvestigation dispute and hope the furnisher cooperates. The Fair Credit Reporting Act gives you a faster, stronger remedy in §605B: the credit bureau must block the item within four business days of receiving sufficient proof, and the furnisher is then barred from re-reporting the item unless they affirmatively prove it is not from identity theft.

§605B was added to the FCRA by the FACT Act of 2003 specifically to address the explosion of identity-theft cases that the existing §611 reinvestigation process was not equipped to handle. For genuine fraud items, it remains the strongest self-help tool a consumer has under federal law.

The rule in one sentence: A §605B identity-theft block is faster (4 business days) and stronger (presumptive block, burden on the furnisher to overturn) than a §611 reinvestigation.

What FCRA §605B actually requires

§605B(a) imposes a specific duty on consumer reporting agencies (credit bureaus). Upon receipt of from a consumer of (1) appropriate proof of identity, (2) a copy of an identity-theft report, (3) identification of the specific information to be blocked, and (4) a statement that the information is not information relating to any transaction by the consumer, the bureau must:

• Block the disputed information within 4 business days of receiving the complete request.
• Notify the furnisher that the information has been blocked and that the consumer claims it is a result of identity theft.
• Promptly investigate any subsequent challenge to the block by the furnisher.

The statute uses mandatory language: the bureau "shall" block. There is no discretion to refuse a complete and valid §605B request.

§605B vs §611: which to use

The standard FCRA dispute path is §611 — the bureau opens a reinvestigation, contacts the furnisher, and the furnisher either confirms or modifies the data within 30 days. §605B is a parallel but stronger path designed specifically for identity-theft items:

For genuine identity-theft items, §605B is almost always the better path. For accuracy issues that are not fraud-caused (wrong dates, wrong amounts, mixed file errors), §611 is the right tool.

The four required elements of a §605B request

The statute is unforgiving: a §605B request that is missing any of the four required elements may be rejected by the bureau as incomplete, and the 4-business-day block clock does not start until the bureau receives a complete request.

1. Appropriate proof of identity

A government-issued ID (driver's license, state ID, or passport) AND proof of current address (utility bill, lease, or mortgage statement dated within the last 90 days). Photocopies; never send originals.

2. A copy of an identity-theft report

§603(q)(4) defines an identity-theft report as either:

• A report filed with a federal, state, or local law-enforcement agency — typically a police report; OR
• A report through the FTC's IdentityTheft.gov which produces a complete identity-theft affidavit (often called an FTC Identity Theft Report).

Either is acceptable. The FTC report is usually faster — you complete it online in about 30 minutes and immediately receive a printable affidavit and recovery plan.

3. Specific identification of the information to be blocked

The §605B request must identify each fraud item specifically — by furnisher name, account number as reported, account-open date, and brief description. Generic language like "please block all fraudulent items" fails the specificity requirement and produces rejected requests.

4. A statement that the information is not from a consumer-authorized transaction

This is built into the IdentityTheft.gov affidavit — the consumer signs under penalty of perjury that the disputed transactions were not authorized. If using a police report instead, the consumer's separate signed affidavit must include this language.

When §605B applies — and when it doesn't

§605B applies to:

• Credit accounts opened in your name without your authorization (credit cards, loans, utility accounts, lines of credit).
• Authorized-user fraud — someone added you as authorized user on their account without your knowledge.
• Hard inquiries from creditors you did not apply with.
• Public records (judgments, tax liens) tied to identity-theft accounts.
• Address changes you didn't authorize that appear in your credit file.

§605B does NOT apply to:

• Accounts you authorized but later disputed (e.g., "I opened this card but the fees are unfair"). That's a §611 / §623 dispute, not identity theft.
• Authorized accounts where the spouse or family member used the card without your knowledge. That's typically considered an unauthorized-use issue with the issuer, not identity theft under §605B.
• Mixed-file errors where another person's data appears on your report. That's a §611 mixed-file dispute, not identity theft (though both tools can be appropriate in different scenarios).

Filing a false identity-theft report is a federal crime under 18 U.S.C. §1028A. §605B is the right tool for genuine fraud; the wrong tool for ordinary disputes.

What happens after the bureau blocks the item

Once the §605B block is in place:

1. The item is hidden from your credit file and does not appear on credit reports provided to third parties (lenders, landlords, employers).
2. The bureau notifies the furnisher of the block.
3. The furnisher cannot continue reporting the item to any bureau unless they affirmatively challenge the block.
4. If the furnisher challenges the block with evidence the item is not from identity theft, the bureau investigates. The block may be temporarily lifted while the investigation is underway. If the furnisher's evidence is insufficient, the block stands.
5. The block has no statutory expiration. Unless overturned by the bureau or the furnisher with sufficient evidence, it remains in place indefinitely.

Pair §605B with §623 notice to the furnisher

§605B blocks the item at the bureau level — the credit report no longer shows it. But the underlying account at the furnisher (the fraudster's open credit card, for instance) remains open and active in the furnisher's systems, where it can accumulate fees, be sold to other collectors, or be re-reported under a different identifier.

The complete fraud-remediation sequence is:

1. File the FTC identity-theft report at IdentityTheft.gov.
2. Send the §605B block request to each affected credit bureau (use the bureau's identity-theft-specific address, not the standard dispute address).
3. Send a parallel §623 letter directly to the furnisher citing the identity-theft report and demanding the account be closed, all fees reversed, and no further reporting attempted.
4. Monitor your credit reports at annualcreditreport.com for the next 12 months to catch any related items the fraudster may have opened.

DisputeValet.com generates the §605B letter and the parallel §623 furnisher notice from a single intake, with the bureau-specific fraud addresses and the §623 specificity language already in place.

Frequently asked questions

Do I have to file a police report, or is the FTC report enough?

Either is sufficient under §603(q)(4). The FTC's IdentityTheft.gov report is generally faster to obtain (online, ~30 minutes) and produces a complete signed affidavit. A police report may carry more weight with certain furnishers in subsequent litigation, but it is not required for §605B.

Can the bureau refuse to block?

§605B uses mandatory language ("shall block"). However, the bureau may temporarily decline to block, or rescind a block, if it has reasonable evidence that (a) the request itself is materially incorrect, (b) the block was previously rescinded for sufficient evidence the item is not fraud, or (c) the consumer obtained the relevant goods or services from the transaction. These are narrow exceptions designed to prevent abuse, not to give the bureau general discretion.

How long does a §605B block last?

Indefinitely, unless overturned. There is no statutory expiration. A block remains until the bureau or furnisher produces evidence sufficient to lift it.

What's the difference between a §605B block and a §605C active duty alert / fraud alert?

A §605B block hides a specific item that resulted from identity theft. A §605A fraud alert (initial, extended, or active-duty) is a notice on your credit file that requires creditors to take extra steps to verify your identity before opening new accounts in your name. The two work together but address different problems — block existing fraud items, alert against future fraud attempts.

Will a §605B block affect my credit score?

Yes, but typically in your favor — the fraud item is removed from score calculations as soon as it is blocked. Whether your score improves significantly depends on how negative the blocked item was relative to your overall file.
