Effective immediately, the Postal Operations Manual (POM) is revised to reflect that the Postal Service™ no longer uses the term “philatelic center postmark”; the new term is “philatelic service postmark.”
Philatelic service postmarks are permanent pictorial rubber hand stamps that are permitted for large city Post Offices with philatelic centers or windows. Postmarking service is available only at authorized philatelic centers or philatelic windows and is generally used for postmarking mail entering the mailstream. The use of philatelic service postmarks outside of a philatelic center or window (e.g., tourist sites and museums) must be reviewed and approved by Stamp Services.
