How long after the initial order can a customer file for another change of address using PS Form 3546X?

A customer can file for another change of address using PS Form 3546X within 18 months after the initial order. This policy allows customers the flexibility to update their address information if needed, ensuring that their mail continues to reach them accurately.

Filing for an address change within this timeframe helps accommodate situations like extended travel, moving to a different location, or changes in personal circumstances that may require additional updates beyond the initial request. By limiting this timeframe to 18 months, the Postal Service balances the need for flexibility with the need to manage address changes efficiently in their system, which could potentially become overly complicated with longer durations.

Other options do not provide the correct timeframe established by postal regulations. For example, a duration of 12, 24, or 6 months does not align with the Postal Service’s established procedures for handling change of addresses, which may lead to confusion regarding the validity of the address changes.
