UPDATE 153: International Mail Service Updates Related to COVID-19

On April 6, 2021, the Postal Service™ received a notification from Servicios Postales del Perú - SERPOST S.A, the designated operator of Peru, advising that SERPOST is taking the necessary steps to re-establish service levels and restore normal operations for all types of mail (letter-post, parcel-post and EMS items), including the delivery of mail on the national territory. In addition, the air transport sector is steadily recovering, allowing SERPOST to lift the force majeure previously declared with respect to the acceptance and processing of international items.

Unless otherwise noted, service updates to a particular country do not affect delivery of military and diplomatic mail.

This service update affects Priority Mail Express International® (PMEI), Priority Mail International® (PMI), First-Class Mail International® (FCMI), First-Class Package International Service® (FCPIS®), International Priority Airmail® (IPA®), International Surface Air Lift® (ISAL®), and M-Bag® items.

The DMM Advisory will continue to provide updates as they are received. For a full list of international service disruptions, please visit
