United Parcel Service (UPS) is set to implement significant changes to its SurePost service, which has long relied on the United States Postal Service (USPS) for final-mile deliveries, following the expiration of their recent contract,

UPS recently ended a contract with the United States Postal Service and delivery changes are coming to some post office box users as a result.

UPS SurePost packages will be delivered by UPS drivers only after a contract between UPS and USPS expired this year.

U.S. Postal Service (USPS) workers will no longer deliver UPS SurePost packages after the government agency's contract with the parcel service expired this year. The International Brotherhood of Teamsters, a union representing UPS delivery drivers, confirmed the negotiated service agreement's expiration in a Facebook post last week.
