Did you know that you can cancel your own mail? With a free permit and an inexpensive rubber stamp, the United States Postal Service will allow you to cancel your own mail. Cancelling your own mail is fun. In addition, if you are a stamp collector, you can insure that the mail you send out has neat, properly placed and clean postmarks.


This web site will teach you how to obtain your own Mailer's Postmark Permit, how to obtain the proper rubber stamp to cancel your mail, and how to submit your mail to the post office. In addtion, we'll cover the history of Mailer's Postmark Permits and show you how they have been used over the years.
