In 1989 Louth Scouts produced a souvenir cover. The cover carried a copy of Grimsby & Cleethorpes issue #1 of 1985, hand annotated "LOUTH" in black. Other than on this cover usage of the the Grimsby & Cleethorpes stamps by Louth cannot be established, furthermore no other evidence of a separate postal service for Louth has yet been obtained. The area is normally within the Grimsby & Cleethorpes postal service.
Louth is a District within the Scout County of Lincolnshire.
