15 U.S.C. 1681i: the 30-day credit-dispute investigation clock

The short answer. When you dispute an item on your credit report directly with a consumer reporting agency (a credit bureau), the Fair Credit Reporting Act (FCRA) starts a clock the moment your dispute arrives: the bureau has 30 days to complete a reasonable reinvestigation, and that window stretches to 45 days only if you hand it new relevant information partway through. The statute that runs this clock is 15 U.S.C. 1681i, plainly titled “Procedure in case of disputed accuracy.” Most consumers know the phrase “30-day rule” without knowing which subsections fire when. This page is a clean map of that clock — nothing more, nothing less.

What 15 U.S.C. 1681i actually governs

Section 1681i governs what a credit bureau must do once you tell it that something in your file is wrong. It is the bureau-facing half of the dispute system. It does not, by itself, describe how you choose where to send the dispute, and it is not the section that defines what the company reporting the debt has to do — that company, the furnisher, lives under its own statute. If you want the decision tree for where a dispute goes, that belongs in the discussion of the 623 dispute versus the 611 dispute. If you want the practical, step-by-step mechanics of writing and filing one, that is the how-to on disputing credit report errors. Here we stay strictly on the clock: when each obligation under 1681i is triggered, and what happens if the deadline arrives without an answer.

The clock, hour by hour

The discipline of 1681i is that it attaches a specific deadline to each step, and those deadlines run from concrete events rather than from vague notions of “soon.” The original investigation must be completed within 30 days of the bureau receiving your dispute, a deadline set in 1681i(a)(1)(A). That 30-day figure is the number worth memorizing, because it is the one most likely to be missed.

The only way the clock extends is narrow and specific. Under 1681i(a)(1)(B), the bureau may take up to 15 additional days — a maximum of 45 days in total — but only if you provide additional relevant information during the original 30-day period. In other words, the extension is not a courtesy the bureau can claim at will; it is a consequence of your own mid-stream submission. If you file once and add nothing, the deadline stays at 30 days, full stop.

There is an early, quieter deadline that often goes unnoticed and matters enormously. Within 5 business days of receiving your dispute, the bureau must forward all relevant information to the furnisher, a requirement in 1681i(a)(2). This forwarding is the hinge of the whole system, because it is the step that triggers the furnisher’s privately-enforceable duties under 15 U.S.C. 1681s-2(b). A dispute sent only to the furnisher and never routed through the bureau does not pull that lever in the same way, which is one more reason the routing question is worth getting right.

Why “cannot be verified” is the part with teeth

The most powerful sentence in the section is also the most overlooked. Under 1681i(a)(5)(A), if the disputed item is inaccurate, incomplete, or cannot be verified, the bureau must promptly delete or modify it. Read that standard carefully, because the word “cannot be verified” does the heavy lifting. The burden is not on you to prove the item is wrong; the burden is on the bureau and the furnisher to substantiate that it is right. An item that no one can affirmatively confirm — because the records are gone, the furnisher does not respond, or the documentation does not hold up — fails the test and has to come off, even if no one has proven it false. That burden-shift is what makes the 30-day clock more than a formality. A deadline that simply passed would be toothless; a deadline that passes with the item unverified forces a result. And the reinvestigation duty sits alongside a separate, earlier obligation: the bureau must build the report accurately in the first place under the maximum possible accuracy standard of 15 U.S.C. 1681e(b) — two distinct claims that can be pleaded together.

After the investigation: results and the brief forward-pointer

When the bureau finishes, it owes you an accounting. It must notify you of the results within 5 business days of completing the reinvestigation. From there, you gain a follow-up right: you can request a description of the procedure the bureau used to determine the accuracy of the item, a right found in 1681i(a)(6)(B)(iii), and the bureau must provide that description within 15 days under 1681i(a)(7). This is the so-called “method of verification” disclosure, and it is genuinely useful when a furnisher keeps “verifying” an item that you are confident is wrong. It carries enough nuance to deserve its own treatment, which is why we cover it in full in the guide to the method of verification letter; for the purposes of the clock, the thing to remember is simply that the right exists and that it has its own 15-day deadline once you ask.

The timeline at a glance

The cleanest way to hold all of this is to lay the subsections against a calendar that starts on the day your dispute lands.

• Day 0 — The bureau receives your dispute. The 30-day clock under 1681i(a)(1)(A) begins.
• By Day 5 (business) — The bureau must forward all relevant information to the furnisher under 1681i(a)(2), triggering the furnisher’s 1681s-2(b) duties.
• During Days 0-30 — If you add new relevant information in this window, and only then, the deadline extends to 45 days under 1681i(a)(1)(B).
• By Day 30 (or Day 45 if extended) — The reasonable reinvestigation must be complete. Anything inaccurate, incomplete, or unverifiable must be promptly deleted or modified under 1681i(a)(5)(A).
• Within 5 business days of completing — The bureau notifies you of the results.
• On request, within 15 days — The bureau provides the method-of-verification description under 1681i(a)(6)(B)(iii) and (a)(7).

What to do when the clock runs out

If the 30 days (or the extended 45) pass without a proper, completed reinvestigation, the bureau has fallen out of compliance, and an item that could not be verified within that window is supposed to be deleted, not left to linger. Knowing the exact deadline is what turns a vague complaint into a specific demand.

But the heart of 1681i is this: a dated clock, a short list of obligations tied to it, and a burden of proof that sits on the bureau rather than on you.
