At what time mailman leave undelivered mail to post office

The time at which a mail carrier leaves undelivered mail at a post office can vary depending on several factors, such as the specific post office, the mail carrier's route, and the volume of mail being handled. However, I can provide some general information on the typical procedures and times.

In the United States, mail carriers typically follow these guidelines:

  1. End of the day: Mail carriers usually deliver mail to their assigned routes during the day, and then return to the post office at the end of their shift. This is typically around 5:00-6:00 PM, but can vary depending on the specific post office and the mail carrier's schedule.
  2. Undeliverable mail: If a mail carrier has undeliverable mail, such as packages or letters with incorrect addresses, they will typically bring them back to the post office at the end of their shift. This is usually done in a designated area, such as a "dead mail" or "undeliverable mail" bin.
  3. Post office processing: The post office will then process the undeliverable mail, which may involve:
    • Sorting and categorizing the mail by type (e.g., packages, letters, etc.).
    • Attempting to forward the mail to the correct address (if possible).
    • Returning the mail to the sender (if the address is incorrect or incomplete).
    • Destroying the mail (if it's deemed undeliverable due to incorrect or incomplete information).

The exact timing of when mail carriers leave undelivered mail at the post office can vary, but it's usually around the end of their shift, which is typically between 5:00-6:00 PM. However, it's possible that mail carriers may leave undeliverable mail at the post office earlier or later in the day, depending on their specific schedule and the volume of mail being handled.

Keep in mind that these are general guidelines, and the specific procedures and times may vary depending on the post office and the mail carrier's route.
