Accordingly for a movie that showed aspects of phone phreaking techniques and culture, Hackers (1995) mentions at least three 555 numbers:
212-555-4240: The number of the modem at OTV that Dade social-engineers out of the security flunkie, allowing him to dial into the cable channel's systems
555-4817: Lisa Blair's phone number, which Lord Nikon recalls out of his photographic memory at the party.
555-4202: Kate's number, which Phreak connects to by rapidly pressing the prison phone's switchhook ten times (effectively pulse-dialing 0) and then asking the operator for help dialing
Given how stylized the movie is as a whole, the prominence of several obviously-fake phone numbers is the least of the things that break realism.
