16 CFR 314.4(c)(6)(i) — secure disposal
Develop, implement, and maintain procedures for the secure disposal of customer information in any format no later than two years after the last date the information is used in connection with the provision of a product or service to the customer to which it relates…
The two-year clock runs from last use, not from collection or from account closure. The same sentence carries exceptions — where retention is necessary for business operations or other legitimate business purposes, where law or regulation requires retention, or where targeted disposal is not reasonably feasible given how the information is maintained. A page that states a flat two-year destruction mandate without those exceptions is misreading the rule.
