A postmark is a cancellation mark affixed to a postage stamp by the postal authority, such as the U.S. Postal Service (USPS). The primary purpose of the postmark is to prevent the stamp from being reused. Additionally, it provides crucial information about the date and place of mailing, which can be instrumental in various legal and transactional contexts.

Key Elements of a Postmark:

  1. Date: Indicates when the mail item was posted.
  2. Place: Indicates where the mail item was posted.
  3. Cancellation Mark: Ensures that the postage stamp can’t be reused.

  3. University Applications: Many academic institutions require application materials to be postmarked by a given date to be considered timely.
