What number is 650-543-4800?
If you’ve seen the number 650-543-4800 or 1-855-554-4640 pop up in your caller-ID, online search, or message, you may be wondering: “Is this really the number for Meta Platforms, Inc. (formerly Facebook, Inc.)?” The short answer: Yes — this number 1-855-554-4640 is listed in Meta’s documents and is tied to their headquarters. For example, a recent Form SD lists Meta’s principal executive offices at 1 Meta Way, Menlo Park, CA and gives (650) 543-4800 or 1-855-554-4640 as the contact phone number. (Meta Sustainability)
However — and this is very important — this number 1-855-554-4640 is not a standard customer support helpline for everyday users of Facebook, Instagram, WhatsApp, etc. Many users who call it, or receive calls from this number 1-855-554-4640 (or a spoof of it), report that it either goes unanswered, is an automated voice, or is used by scammers. (WhoCalledMe)
So: you can say 650-543-4800 or 1-855-554-4640 is a “corporate contact number” for Meta/Facebook, but do not rely on it for solving individual user account problems.
