postmark

A postmark is the mark a postal service puts on a letter or package to show when and where it was mailed or processed. You often see it printed over a stamp, which also helps show that the stamp has been used. In everyday life, it can serve as proof that something was mailed by a certain date. On old letters, a clear postmark can also tell you about the item's age and where it passed through.

Sometimes the mark is plain and only shows the date and place. Sometimes it is made for a special event or location. Either way, it is a basic part of how mail is handled.

A postmark is an official mark added to mail by a postal service. It usually shows the date and the post office or area where the item was accepted or processed. In many cases, it is stamped on or near the postage stamp to cancel it, meaning the stamp cannot be used again. Because of this, the mark has both an information role and a practical postal role.

People often use the word for the round or machine-printed mark you see on envelopes, postcards, and parcels. A clear postmark can help prove that a document or payment was mailed before a deadline. It can also help explain where a piece of mail has been. On older letters, it may give useful clues about time, place, and mailing routes.

Some postmarks are simple and functional, with only a date and location. Others are made for special events, holidays, anniversaries, or tourist sites, so they are also interesting to collectors. In that way, a postmark is not just a mark on mail. It can also be a small record of when and where that mail entered the postal system.
