Only FedEx-approved, licensed alcohol shippers that have entered into a FedEx Alcohol Shipping Agreement may ship alcohol via FedEx services. Consumers may not ship alcohol of any type via FedEx services.
For all alcohol shipments, you’ll need to sign a FedEx Alcohol Shipping agreement. Contact your FedEx account executive for details and assistance and if you don't have an assigned account executive, call FedEx Customer Services at 1.800.463.3339.
Adult signature service option. State law, as well as FedEx policy, requires an adult signature at the time of delivery for every U.S. package containing alcohol. It is your responsibility to ensure the adult signature requirement service option is selected so that FedEx requests and obtains the required adult signature. A $5.75 fee per shipment applies for this service.

FedEx currently only permits wine shipments under licensee-to-consumer agreements; beer and spirits require licensee-to- licensee.
Licensee-to-consumer
FedEx only transports wine licensee-to-consumer.

UPS only accepts packages containing wine from shippers who are licensed under applicable law and who have signed and entered into a contract with UPS for the transportation of wine.
All wine shippers must enter into a UPS Agreement for Approved Wine Shippers.
All alcohol shippers must schedule a consultation call or speak to their Account Manager to review UPS alcohol shipping policies, submit copies of your state licenses, and complete a shipping agreement.
The ability to ship wine depends upon the nature of the shipper's license to sell wine, and the laws of the destination states. UPS permits the following types of wine shipments:
Shipments of wine from licensed shippers may be shipped to licensed consignees, where permitted by applicable law. For example, a licensed manufacturer may ship to a licensed distributor, or a licensed distributor may ship to a licensed retailer, so long as the shipments are made in accordance with applicable law. "Licensed to Licensed" shipments cannot be made to consumers.
All wine shipments must be made using the UPS Delivery Confirmation Adult Signature Required service, requiring the signature of an adult 21 years of age or older upon delivery.
Some states also allow shipments of wine from out-of-state licensed wine retailers to consumers. These states are known as "Retailer Direct Shipment States." Shipments of wine from licensed out-of-state retailers may be made to consignees in "Retailer Direct Shipment States" subject to all of the conditions applicable to Winery Direct Shipment States, except that the purchase is made from a licensed out-of-state retailer rather than a winery. Refer to Addendum A for approved Retailer Direct Shipment States.
All shippers who wish to ship wine must enter into either the UPS Agreement for Approved Wine Shippers, or the UPS Wine Industry Fulfillment House Agreement For Approved Wine Shippers. UPS DOES NOT ACCEPT SHIPMENTS OF WINE FROM SHIPPERS WHO HAVE NOT ENTERED INTO ONE OF THESE AGREEMENTS.
