Postmarks for 2025

A postmark is an inked rubber stamp, with an imprint that indicates the date and place. A postal worker will press the postmark onto your letter to show the stamp has been used for postage. The date on the postmark records where and when the item enters the mail system.

Postmarks are just as unique and fascinating as stamps themselves. Take a look at some of our latest ones, and learn how to perfectly place postmark ink onto your collectable items.
