S. 1663 was introduced by Sen. Jeff Merkley (D-OR). The legislation is identical to H.R. 3287. The measure would allow USPS to ship alcoholic beverages directly from licensed producers and retailers to consumers over the age of 21, in accordance with state and local shipping regulations. The bill will give USPS two years to develop regulations and implement the law, ensuring USPS is ready to safely deliver alcoholic beverages to adult consumers with appropriate identification checks in place.
