Facebook Telephone Number
Founded in 2004, Facebook is an American online social-media and social-networking service company based in Menlo Park, California. Facebook has more than 2.2 billion active users.

How to Contact Facebook by Phone
There is no Facebook Customer Services number because FB does not have a call centre. You may find 0844 735 4595 offered on the internet as the Facebook telephone number. This is a PHISHING SCAM and not a legitimate way to get in touch with the company.
