If you call the number on the “missing teen” poster in Stranger Things Season 5, it has a message from the “Hawkins Police Dept” looking for Jane Hopper, fans have confirmed.

The missing poster in question appears during Season 5, Episode 1, as the military hunts Eleven, played by Millie Bobby Brown, down. On the poster, displayed in Hawkins High School, an Indiana area code phone number can be seen (Hawkins is a fictional town but it is meant to be set in Indiana).

The Stranger Things Season 5 ‘missing teen’ poster phone number:

• 765-303-2020

This number actually works (we’ve verified it). It triggers a fictional answer from the Hawkins Police Department in which callers are told that “due to the recent 7.4 magnitude earthquake, Hawkins is currently under lockdown to ensure the safety of our residents." There’s an Emergency Task Force that’s working with the police to track down Jane Hopper as “a priority,” callers are told. "We urge you, as a responsible citizen of Hawkins, to assist in our search to locate her," the message concludes.

This fun real-world Easter egg ties in directly with the plot of Season 5, described as follows:

The fall of 1987. Hawkins is scarred by the opening of the Rifts, and our heroes are united by a single goal: find and kill Vecna. But he has vanished — his whereabouts and plans unknown. Complicating their mission, the government has placed the town under military quarantine and intensified its hunt for Eleven, forcing her back into hiding. As the anniversary of Will’s disappearance approaches, so does a heavy, familiar dread. The final battle is looming — and with it, a darkness more powerful and more deadly than anything they’ve faced before. To end this nightmare, they’ll need everyone — the full party — standing together, one last time.

It turns out this number has been doing the rounds since January, when it appeared on a social media post promoting Stranger Things. It worked then, too, fans found, returning the same message and setting up the events to come.

Stranger Things Season 5 debuts on Netflix in three parts, with the first four episodes arriving on November 26. The next three episodes premiere on Christmas, and the series finale will debut on the streamer and in over 350 theaters nationwide on New Year’s Eve.

Stranger Things Season 5 release dates:
