During the holidays, increased volume and weather conditions may affect the Postal Service’s ability to transport all Priority Mail Express® 1-day shipments. Like our competitors, the Postal Service™ has an adjusted postage refund policy for Priority Mail Express items sent from December 22 through December 25, 2022.
While the Postal Service fully expects Priority Mail Express 1-day service to remain where available, postage will not be refunded unless the first delivery attempt or delivery occurs more than two delivery days after the acceptance scan event. For questions about this policy, send an email to ShippingServices@usps.gov.
Additionally, beginning July 1, 2023, USPS® Corporate Accounts will no longer be available as a payment method. Customers must switch to a new method of payment as soon as possible. For assistance with account migration, contact the sales representative for your territory or send an email to the Mailing and Shipping Services Center at MSSC@usps.gov.
