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

Under the change, UPS Sure Post packages are now only being delivered by UPS drivers, a spokesperson for the International Brotherhood of Teamsters spokesperson told Supply Chain Dive. In the past, the final leg of these deliveries was made by the U.S. Postal Service; now, they will be handled by UPS after the Jan. 1 contract expiration.

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.

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.
