The Kennedy Space Center’s post office, a contract facility that has been in operation since July 1, 1965, is set to shut its doors for good by the end of this fiscal year, which concludes on September 30.

The post office has been managed by Post Masters Mail and Print Services, a division of the non-profit Anthony Wayne Rehabilitation Center (AWRC), on behalf of NASA since 2013.

With the closure, all mail from the agency will be rerouted through Cocoa Beach to Orlando for processing. This means that the public will no longer have the option to request special Kennedy Space Center postmarks on stamped envelopes, commonly known as philatelic “covers.”

Collectors who wish to have their envelopes postmarked will now be directed to the Titusville post office, the next closest facility to the space center. The U.S. Postal Service will also cease to offer Kennedy Space Center postmarks through its fulfillment center in Kansas City, Missouri.

The Kennedy Space Center post office has been a significant part of space history, especially for collectors. Thomas Spaur, the supervisor of the post office, revealed that they received an average of 5,000 postmark requests annually. Since the Apollo 12 launch in 1969 and the end of the space shuttle program in 2011, drop boxes for these special postmarks were available at the Kennedy Space Center Visitor Complex.

Those who wish to obtain a postmark dated for the last day of service should send their requests to the Kennedy Space Center post office by September 15. After the closure, all cover requests should be directed to the Titusville Post Office.

For additional details, collectors can send their stamped envelopes and postcards to the following address:

After the office closes, cover requests should be sent to:
