Setting Up USPS

Learn how to connect your USPS account to buyback.ai

buyback.ai supports USPS MRS service. These are the labels that can be automatically generated for your customers at checkout. You and your customers are not charged for these labels until the package gets delivered. If your customer does not use the label there is no further action needed. This is especially helpful, time-saving, and cost-effective when running a mail-in buyback service at a large scale.

Please note this can take several weeks to get all of the information required to set this up from USPS. We recommend starting with FedEx or UPS returns first if you are new to buyback.
