From the USPS DMM Advisory:
As the situation in Egypt continues to evolve, our acceptance policy for mail destined to that country also is evolving. Effective immediately, all Post Officeâ„¢ and other mail acceptance locations cannot accept any mail addressed to recipients in Egypt.
This temporary suspension affects Global Express GuaranteedÂ® (GXGÂ®), Express Mail InternationalÂ®, Priority Mail InternationalÂ®, First-Class Mail InternationalÂ®, International Priority Airmailâ„¢ (IPAÂ®), International Surface Air LiftÂ® (ISALÂ®), and M-Bag items.
Mail addressed to Egypt that has already been accepted by the Postal Service will be returned to sender. Upon request, the Postal Service will refund postage and fees on items returned due to the temporary suspension of service
We will use the DMM Advisory to keep you informed of any further developments affecting mail delivery to Egypt. To subscribe to the DMM Advisory, send an e-mail to firstname.lastname@example.org. Simply indicate “subscribe” in the subject line.
