Can post office check mailing date

Yes, the United States Postal Service (USPS) can verify the mailing date of a piece of mail. Here are a few ways to do so:

  1. Postmark: The postmark on the envelope or package can indicate the date it was mailed. The postmark is usually a stamp or a sticker with the date and time it was processed at the post office.
  2. Post Office Records: The USPS maintains records of all mail processed at their facilities. You can visit a local post office and ask the clerk to check their records to verify the mailing date. They may need to access their computer system or check a physical logbook to find the information.
  3. Tracking Number: If you have a tracking number for your package, you can use the USPS website or a tracking service like USPS Tracking to check the delivery status and estimated delivery date. The tracking information may also include the date the package was mailed.
  4. Certified Mail: If you used Certified Mail to send a package, you can request a certified mail receipt from the USPS. This receipt will include the date the package was mailed and signed for by the recipient.
  5. Online Tools: Some online shipping platforms, such as Stamps.com or Endicia, allow you to track your mail and access mailing records online.

Keep in mind that the USPS may not always be able to verify the exact mailing date, especially if the mail was processed at a busy post office or if the records are no longer available. However, they can usually provide an estimated mailing date or confirm that the mail was processed on a specific date.
