What type of address change is most likely to have no expiration date with USPS?

A permanently registered address is the type of address change with no expiration date with USPS. This form of address change is typically used when a person changes their primary residence and intends for that change to be long-lasting or indefinite. Unlike temporary or seasonal address changes, which are intended for shorter durations and have specific time frames associated with them, a permanently registered address does not require renewal or reinstatement, ensuring that mail is consistently directed to the correct and ongoing location.

In contrast, temporary address changes have specified time limits during which the mail is redirected and will automatically expire after that period. International address changes might involve specific regulations and adjustments based on international postal agreements and may not necessarily apply to every context. Seasonal address changes are made for particular times of the year, indicating that they are also not permanent.
