Glasser is an area within the Northwood section of the Borough of Hopatcong, in Sussex County, in the U.S. state of New Jersey.

While not officially a municipality, the area was granted its own post office in 1933 by the United States Postal Service that was later assigned ZIP Code 07837.

Currently the area contains a small US Post Office, several residential apartments and bungalows, and a restaurant and bar overlooking Lake Hopatcong.

A correspondence with Garmin's support explained that because of Glasser's unusual status "the street addressing is assigned to a surrounding ZIP (in this case Andover, New Jersey 07821).

"[2] One resident who held a box at Glasser in the 1980s, Dennis Burnham, reports that when he began using a postage meter, Elmer Hobbs was thrilled because it required him to requisition the official crimping tools from the USPS, making it harder for the government to shut down a post office in which there is a metered customer.
