Fallout 4's Vault-Tec phone number actually works if you call it

The 1-888 Vault-Tec phone number seen in Fallout 4 works. The phone number of Vault-Tec, the fictional in-game company that built the vault your character emerges out of, is actually a functioning number you can dial in real-life. The 1-888-4-VAULT-TEC number may look a bit longer than most, but it does work, as Polygon discovered.
