**Validation period** — The validation period is the window that opens on the date a debt collector provides the required validation information and closes 30 days after the consumer receives or is assumed to receive it.

Section 1006.34(b)(5) supplies a counting convention: "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." Collection activity during the period must not, in the words of 15 U.S.C. § 1692g(b), "overshadow or be inconsistent with the disclosure of the consumer's right to dispute the debt" — the doctrine practitioners call overshadowing, and the reason demand language and suit threats are usually suppressed until the window closes. A written dispute inside the window stops collection until verification is mailed under § 1006.38(d).
