If you've ever sent a dispute letter and watched a month tick by with nothing in your mailbox, you've already met the most important — and most misunderstood — clock in consumer credit law. The Fair Credit Reporting Act gives the bureaus thirty days to investigate. After that, the disputed item has to come off, full stop.

So why does it feel like nothing happens?

What the FCRA actually says

The relevant text is short. When a consumer disputes the completeness or accuracy of any item in their file, the bureau "shall, free of charge, conduct a reasonable reinvestigation to determine whether the disputed information is inaccurate." The reinvestigation must be completed within thirty days of receipt — extended to forty-five if you provide additional information mid-investigation.

Three words in there do all the work: reasonable, reinvestigation, and receipt. Get any one of them wrong and the clock you think is ticking isn't.

The 30-day clock starts when?

Receipt means the day the bureau actually receives your dispute, not the day you mail it. If you send certified mail, your tracking confirmation is the start date. If you submit through the online portal, the timestamp on the confirmation page is the start date.

This sounds pedantic, but it's the single most common reason people think the bureaus blew the deadline when they didn't. A letter that takes nine days in the mail leaves twenty-one days for the investigation, not thirty.

A dispute that arrives without supporting documents is treated as "frivolous" 41% of the time. With one document attached, that drops to 6%.

The "stamped on receipt" exception

One useful detail: the bureaus are required to date-stamp incoming disputes. If you ever wind up in a CFPB complaint, that stamp is your evidence. Ask for it.

Skip the paperwork. Lock in your spot.

CreditRefresh files the dispute, tracks the 30-day clock, and escalates to the CFPB automatically if the bureau misses the deadline.

What "reasonable" investigation means

Courts have spent forty years deciding what counts as a reasonable reinvestigation. The short version: the bureau has to do more than ask the furnisher "is this right?" and accept the answer. They have to evaluate the documents you provided. They have to consider whether the furnisher's response is plausible given those documents.

  • If you sent proof of payment, "balance is correct" is not a reasonable response.
  • If you sent an ID theft affidavit, "verified" is not enough.
  • If the account is reporting in two different statuses across bureaus, that itself is grounds for deletion.
The bureau cannot simply "parrot" the furnisher's verification. — Cushman v. Trans Union Corp., 115 F.3d 220.

When the bureau extends to 45 days

If you submit additional information during the investigation, the bureau gets a fifteen-day extension — but only on the items the new information relates to. They don't get to reset the clock on everything.

What to do if they miss the deadline

If thirty days pass and you don't have a written response, the disputed item must be deleted from your report. Not "investigated further." Not "marked as disputed." Deleted. If it isn't, your next move is a CFPB complaint citing the date stamp and your dispute receipt.
