The Philosateleian postmark consists of the letter P in a circle, with five horizontal cancellation bars to the right of the circle. The bars represent the five administrative regions of Philosateleia, while the circle represents the satellite as a whole.

Classic Postmark

Two styles of the postmark can be found on Philosateleian stamps. The circle and horizontal bars of the classic postmark are of inconsistent thickness, and the bars are short. The cancellation is also typically light due to the nature of the clay from which the classic postmarking device was molded.

The classic postmark is found only in conjunction with 2004-1, and was used on approximately 34 pieces of mail between January 7, 2004 (SY164) and May 17, 2004 (SY165) before officials retired the classic device due to its softness. Confirmed examples of 2004-1 bearing the classic postmark include two first day of use covers, a single on piece, and an off-cover single showing only the P and circle, all in the collection of Ambassador Kevin Blackston. It is unknown how many specimens actually survived.

Standard Postmark

The standard postmark replaced the classic postmark on May 17, 2004. Impressions made with the rubber standard postmarking device have a much more polished appearance than those made with the classic device.
