Hello @Seller_a84mYtOUSbbKZ

Christine here from Amazon Forums.

UPS Smart Pickup can indeed be used in conjunction with Amazon's "Buy Shipping" feature, but there are some important points to consider:

• You need to have a UPS account set up and linked to your Amazon seller account for this to work seamlessly.
• Ensure that UPS Smart Pickup is available in your area, as it might not be offered in all locations.
• UPS may have minimum volume requirements for Smart Pickup services, so check if your shipping volume meets their criteria.
• The labels generated through Amazon's Buy Shipping should include all the necessary information for UPS Smart Pickup to detect and process them.
• UPS Smart Pickup is designed to work with UPS shipping labels, including those generated through Amazon's Buy Shipping option.

Let me know if you have any other question regarding this topic.

Christine.
