How long do post office hold undelivered mail

The United States Postal Service (USPS) has a standard policy for holding undelivered mail, which varies depending on the type of mail and the circumstances. Here are some general guidelines:

1. First-Class Mail: The USPS typically holds First-Class Mail for 15 days before returning it to the sender as "undeliverable as addressed." If the mail is not claimed or forwarded within 15 days, it may be returned to the sender.
2. Priority Mail: Priority Mail is typically held for 30 days before being returned to the sender as "undeliverable as addressed."
3. Package Services: Package Services, such as Parcel Post and Media Mail, are typically held for 30 days before being returned to the sender as "undeliverable as addressed."
4. International Mail: International mail is typically held for 30 days before being returned to the sender as "undeliverable as addressed."
5. Special Handling: If a piece of mail requires special handling, such as certified mail or registered mail, it may be held for a longer period, typically up to 60 days, before being returned to the sender as "undeliverable as addressed."

It's worth noting that these timeframes may vary depending on the specific circumstances of the undelivered mail. For example, if the mail is returned to the sender due to an incorrect address, it may be held for a longer period to allow the sender to correct the address.

If you're concerned about undelivered mail, you can contact your local post office or the USPS customer service department to inquire about the status of your mail.
