What is the maximum duration for which mail can be held according to USPS regulations?

The correct answer is that mail can be held for a maximum duration of 30 days according to USPS regulations. This policy is in place to accommodate customers who may be traveling or temporarily unavailable to receive their mail. The 30-day limit is designed to ensure that mail does not accumulate excessively at a delivery address, which could lead to issues such as loss of important communications or increased risk of theft. Customers have the option to place a hold on their mail service through various methods, including online requests or in-person visits to a post office, and this service is intended to provide a convenient way to manage mail delivery during short-term absences.
