ZIP code 56999 was established in September 2012 for USPS Parcel Return Service, a specialized program for processing commercial return shipments. This designation represents one of the earlier PRS codes created in the Washington, D.C. area. The program requires businesses to enter Negotiated Service Agreements with USPS, allowing them to provide prepaid return labels that route packages to designated collection facilities.
Although mapped to the Adams Morgan neighborhood of Northwest Washington, this ZIP functions purely as a mail routing designation without geographic delivery routes or resident populations. The service benefits e-commerce retailers and catalog companies by streamlining the returns process. Customers drop off prepaid packages at any USPS location, and the PRS routing code ensures the parcels reach the business's contracted collection point. Addresses should use "Parcel Return Service" or "PRS" as the city.
ZIP Code 56999 is assigned to a single organization or institution. Detailed business demographics are not published for unique ZIP Codes.
