How long do i have to post franked mail

In the United States, the time frame for posting franked mail, also known as official mail or government mail, depends on the type of mail and the destination. Here are some general guidelines:

1. First-Class Mail: Franked mail sent via First-Class Mail must be postmarked within 3 days of the date of mailing. This applies to mail sent to domestic addresses.
2. Priority Mail: For Priority Mail, the postmark deadline is 5 days from the date of mailing.
3. International Mail: For international mail, the postmark deadline varies depending on the destination country and the type of mail service used. Generally, international mail must be postmarked within 10-14 days of the date of mailing.
4. Special Services: For special services like Certified Mail, Return Receipt, and Priority Mail Express, the postmark deadline may be shorter, typically within 1-3 days of the date of mailing.

It's essential to note that these deadlines are for the postmark date, not the date of mailing. The postmark date is the date the mail is officially stamped and processed by the USPS.

To ensure timely delivery, it's recommended to post franked mail as soon as possible after preparation. If you're unsure about the postmark deadline for a specific type of mail, you can consult with your local post office or the USPS website for more information.
