The Army Post Office (APO) and Community Mail Room (CMR) are two separate services. APOs are for sending mail and CMRs are for receiving mail. On Patch, Kelley, and Robinson these services are located in the same building. On Panzer, they are not.

To open a Community Mail Room (CMR) receptacle (mailbox) requires a copy of orders and a DoD ID card. A CMR box can be assigned either on the installation you work or live.

  • All customers must show a DoD ID card to send or receive mail.
  • All installations have blue USPS mailboxes for regular, stamped, letter mail.
  • A US Forever stamp can be used to mail an item to a German address, if you use your CMR address as the return address.
