RELATED: USPS Is Finally Letting Customers Do This, Effective Immediately. The USPS halted its international mail services to Russia on March 11, Linn’s Stamp News reported. According to the news outlet, the agency said it had suspended certain services “due to unavailable transportation as a result of widespread cancellations and restrictions” within Russia. The services no longer provided include Priority Mail Express International, Priority Mail International, First-Class Mail International, First-Class Package International Service, International Priority Airmail, International Surface Air Lift, M-bags, and Global Express Guaranteed Service, the Postal Service said. On its website, the Postal Service asks that customers “please refrain” from trying to send any mail addressed to Russia in the USPS system. Employees are unable to accept items destined for countries with suspended international mail service. The only exception is the delivery of military and diplomatic mail. According to the USPS, already deposited mail will be marked as “Mail Service—Return to Sender” and then be mailed back to you. But it could cost you. “The Postal Service will, upon request, refund postage and fees on mail returned due to the suspension of service,” the USPS states on its website.
