Although the address of the Gilmores’ house is never given in the show, in the liner notes for the show’s soundtrack, Our Little Corner of the World: Music from Gilmore Girls, a postcard sent by Lane from South Korea is pictured. It is addressed to 37 Maple Street, Stars Hollow. The town’s ZIP code is shown as 06492, the same as Wallingford.
