America's Only Floating Zip Code!
Zip code 48222 is a very special zip code. This zip code is for mail that is delivered to freighter crews or vessels that are underway, meaning ships that are moving. This special service is done by the J.W. Wescott Company that is located just south of the Ambassador Bridge along the western shore of the Detroit River. Right here in Michigan!
This company was founded in 1874 by Great Lakes Captain J.W. Wescott. At that time Captain Wescott used a rowboat to deliver ship’s orders and supplies to passing vessels. In 1895, he began delivering mail.
The boat, the J.W. Wescott II, which was commissioned in 1949, is now used. It is 45’ in length with a beam of 13’. The boat’s speed is rated at 15 knots.
