It appears on a truck early in the movie, and it still works.
It's pretty well known that the original "Friday the 13th" was filmed in northwest New Jersey. There's a real-life phone number and address to prove it.
Early in the 1980 flick that spawned the legend of horror icon Jason Voorhees, a young woman hitches a ride to the fictional Camp Crystal Lake (actually the Boy Scout Camp No-Be-Bo-Sco in Warren County).
Clearly emblazoned on the truck's door is some contact information for an unnamed business that eagle-eyed viewers may have spotted: "347-1063, Waterloo Rd., Stanhope, NJ."
Locals know the address is real: Waterloo Road runs between Hackettstown and Byram Township, and uses a Stanhope mailing address.
But what about the number?
If you dial with Stanhope's 973 area code, you may end up talking to Marc Goldberg. The number goes to his business, Todd/Elston Oil Co.
You wouldn't be the first person. There aren't many calls about the movie these days, probably because it's 37 years old, Goldberg said. But every once in a while someone gives it a try.
One person, apparently after imbibing while watching the movie, called the company around midnight one night and spoke with a night manager.
"He was surprised it was still active," Goldberg said.
Friday the 13th: A holiday in this N.J. town
There is one important distinction: Goldberg's business is based on Route 46 in Netcong, not Waterloo Road.
An overlying 862 area code doesn't lead to a working number. And the 201 area code, which would have served the area in 1980, leads to a voice-over-IP voicemail that went unreturned.
Still, the number -- unlike many of the movie's camp counselors -- is still alive and well.
