UPDATE 143: International Mail Service Updates Related to COVID-19

On March 11, 2021, Estonia Post, the designated operator of Estonia, provided notification that the Estonian government declared a nationwide lockdown on March 11, 2021. While the lockdown is in place, postal services will continue to operate as usual, under certain restrictions. Items normally requiring the addressee’s signature upon delivery will be handed over without signature. Effective March 15, inbound items will be delivered as follows:

  • Registered letters under 2 cm in thickness will be delivered without signature to the recipient’s mailbox. Signature will be given by the postal worker at the time of delivery.
  • Registered letters over 2 cm in thickness that cannot be delivered to the mailbox will be delivered to the addressee without their signature. Signature will be given by the postal worker.

All items that cannot be delivered to a postal box or at the recipient’s address will be transferred to pick-up points.

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.
