The validation period, under Regulation F (12 CFR § 1006.34(b)(5)), is the period starting on the date that a debt collector provides the validation information required by § 1006.34(c) and ending 30 days after the consumer receives or is assumed to receive the validation information. For purposes of determining the end of the validation period, the debt collector may assume that a consumer receives the validation information on any date that is at least five days (excluding legal public holidays identified in 5 U.S.C. 6103(a), Saturdays, and Sundays) after the debt collector provides it. Section 1692g of the Fair Debt Collection Practices Act does not use the term; it refers to a thirty-day period after the consumer's receipt of the notice (15 U.S.C. § 1692g(a)).
Start: the date the debt collector provides the validation information, either in a validation notice sent in the initial communication or within five days of that initial communication, or orally in the initial communication (§ 1006.34(a)(1), (b)(5)). A collector that would otherwise send the notice within five days does not have to if the consumer has paid the debt before then (§ 1006.34(a)(2)).
End: 30 days after the consumer receives or is assumed to receive the validation information; for that count, the collector may assume receipt on any date that is at least five days, excluding legal public holidays, Saturdays, and Sundays, after it provides the information (§ 1006.34(b)(5)).
What a written dispute inside it does: upon receipt of a dispute submitted by the consumer in writing within the validation period, a debt collector must cease collection of the debt, or any disputed portion of the debt, until it sends a copy of verification of the debt or of a judgment, or, for a dispute it reasonably determines is duplicative, takes the steps in § 1006.38(d)(2)(ii) (§ 1006.38(d)(2)).
Where you'll see it
On the validation notice itself. Under 12 CFR § 1006.34(c)(3), the validation information includes the date that the debt collector will consider the end date of the validation period, together with statements about what happens if the consumer disputes the debt in writing, requests the original creditor's name and address in writing, or makes no dispute on or before that date. The CFPB's list of what the notice generally must include ends with an end date for a 30-day dispute period.
The rule behind it
Validation period means the period starting on the date that a debt collector provides the validation information required by paragraph (c) of this section and ending 30 days after the consumer receives or is assumed to receive the validation information. For purposes of determining the end of the validation period, the debt collector may assume that a consumer receives the validation information on any date that is at least five days (excluding legal public holidays identified in 5 U.S.C. 6103(a), Saturdays, and Sundays) after the debt collector provides it.
The three statements tied to the end date (§ 1006.34(c)(3)(i)–(iii)): if the consumer notifies the debt collector in writing on or before that date that the debt, or any portion of the debt, is disputed, the debt collector must cease collection of the debt, or the disputed portion, until it sends the consumer either verification of the debt or a copy of a judgment; if the consumer requests in writing on or before that date the name and address of the original creditor, the debt collector must cease collection of the debt until it sends the consumer the name and address of the original creditor, if different from the current creditor; and unless the consumer disputes the validity of the debt, or any portion of the debt, on or before that date, the debt collector will assume that the debt is valid.
What the CFPB says
Also, if you send the debt collector the written verification request or request for information about the original creditor within this 30-day period, the debt collector must pause collecting the amount of the debt you are disputing until they’ve adequately responded to your request.
While you can submit your dispute at any time, sending it in writing within 30 days of receiving a validation notice, which can be your initial communication with the debt collector, requires them to stop their collection activity until they’ve sent you a verification that responds to your dispute.
Validation period vs. the FDCPA's thirty-day period
Section 1692g does not use the term "validation period." Section 1692g(a)(3) of the FDCPA requires the debt collector's notice (unless the information is in the initial communication or the consumer has paid the debt) to state that unless the consumer, within thirty days after receipt of the notice, disputes the validity of the debt, or any portion thereof, the debt will be assumed to be valid by the debt collector. Section 1692g(b) says collection activities and communications that do not otherwise violate the subchapter may continue during that 30-day period unless the consumer has notified the debt collector in writing that the debt, or any portion of the debt, is disputed or that the consumer requests the name and address of the original creditor, and that any collection activities and communication during the period may not overshadow or be inconsistent with the disclosure of those rights. Regulation F names the window, ties its start to the date the validation information is provided, and lets the debt collector assume a receipt date at least five days, excluding legal public holidays, Saturdays, and Sundays, after providing it (§ 1006.34(b)(5)); the notice then states the end date the debt collector will use (§ 1006.34(c)(3)).
Questions people ask
When does the validation period end?
Under § 1006.34(b)(5), 30 days after the consumer receives or is assumed to receive the validation information. The validation notice states the date that the debt collector will consider the end date of the validation period (§ 1006.34(c)(3)).
Can I still dispute after the validation period ends?
The CFPB says you can submit your dispute at any time, and that sending it in writing within 30 days of receiving a validation notice requires the collector to stop collection activity until it has sent verification responding to the dispute. The CFPB also says that failing to request verification in writing or within this time period can affect your ability to assert your rights under the debt collection rule. The cease-collection duty in 12 CFR § 1006.38(d)(2) applies to a dispute submitted by the consumer in writing within the validation period.
If I don't dispute in time, have I admitted the debt?
Under 12 CFR § 1006.38(d)(1), a consumer's failure to dispute does not constitute a legal admission of liability by the consumer. Separately, the validation notice states that unless the consumer disputes the debt on or before the end date, the debt collector will assume that the debt is valid (§ 1006.34(c)(3)(iii)).
Can a debt collector keep collecting during the validation period?
Under 15 U.S.C. § 1692g(b), collection activities and communications that do not otherwise violate the subchapter may continue during the 30-day period referred to in § 1692g(a) unless the consumer has notified the debt collector in writing that the debt, or any portion of it, is disputed or that the consumer requests the original creditor's name and address. Regulation F likewise provides that during the validation period, a debt collector must not engage in any collection activities or communications that overshadow or are inconsistent with the disclosure of the consumer's dispute rights and right to request the name and address of the original creditor (§ 1006.38(b)(1)).
