The United States Postal Service (USPS) launched a new domestic shipping service called USPS Ground Advantage in July 2023, and Amazon is working to bring this service to sellers with Amazon Buy Shipping. USPS Ground Advantage service offers delivery of packages within 2 to 5 business days in all 50 states.
When Amazon Buy Advantage service is released, sellers will be able to buy labels through Amazon Buy Shipping and existing shipping methods will update automatically to the corresponding USPS Ground Advantage shipping method.
In the meantime, the USPS will continue to accept legacy shipping services for your orders. Amazon will share more information on the launch date and any actions sellers will need to take when they enable the new shipping methods.
