Can you put priority mail in a post box

In the United States, you can indeed put Priority Mail items in a post office mailbox, also known as a blue collection box. However, there are some important considerations to keep in mind:

  1. Size and shape: Make sure your Priority Mail item fits within the mailbox's dimensions. Most post office mailboxes have a maximum size limit of 13 inches long, 12 inches wide, and 3.5 inches thick.
  2. Weight: Priority Mail items have a maximum weight limit of 70 pounds. If your item exceeds this weight, you'll need to take it to a post office or use a larger mailbox.
  3. Special handling: Some Priority Mail items, like those with special handling requirements (e.g., hazardous materials, lithium batteries, or oversized packages), may not be accepted in a mailbox. Check the USPS website or consult with a postal worker if you're unsure.
  4. Postage: Ensure you have the correct postage affixed to your Priority Mail item. You can use a postage stamp or a postage meter.
  5. Tracking: Priority Mail items are trackable, but if you put them in a mailbox, you won't be able to track them until they're processed at a post office.
