The US Postal Service's contract with UPS for SurePost package deliveries has ended. Here is how things will change.

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.
