With Buy shipping you can buy your shipping labels through Seller Central with supported carriers for your seller-fulfilled orders. At this time, BRT is the supported carrier in Italy.
To use BRT as a carrier to fulfil your seller-fulfilled orders via Buy shipping, you will have to complete the registration process using this link. There is no requirement to have an existing BRT account. If you already have an existing account with BRT, you must register a new one with the same link provided above.
After you have completed the registration process, a BRT representative will contact you to get you onboarded. Once the setup is complete and your first BRT collection has been confirmed, you can start purchasing BRT shipping labels through Buy shipping services. Do not buy a BRT shipping label until you have confirmation of setup from BRT.
