Can priority mail bags be drop in blue mailbox

According to the United States Postal Service (USPS), Priority Mail bags can be dropped off at a Blue Collection Box, but there are some limitations and considerations:

  1. Size and weight: Priority Mail bags can be dropped off at a Blue Collection Box if they weigh 13 ounces or less and are no larger than 13 inches long, 11.5 inches wide, and 5.5 inches high.
  2. Special handling: If your Priority Mail bag requires special handling, such as signature upon delivery or insurance, it cannot be dropped off at a Blue Collection Box. You'll need to take it to a post office or a retail location that offers Priority Mail services.
  3. Payment: You'll need to have the correct postage affixed to the bag before dropping it off at a Blue Collection Box. You can purchase postage online or at a post office.
  4. Availability: Not all Blue Collection Boxes are equipped to accept Priority Mail bags. You can check with your local post office or the USPS website to confirm which boxes in your area accept Priority Mail bags.

To ensure your Priority Mail bag is accepted at a Blue Collection Box, make sure it meets the size and weight requirements, and you've affixed the correct postage. If you're unsure, you can always take it to a post office or a retail location that offers Priority Mail services for assistance.
