650-543-4800 / 6505434800

According to internet search sources it is facebooks phone number

It's Facebook's number.

Why is Facebook calling me? Did not awsner. Hope somebody can tell me why.

Facebook called me! Couldn't quite hear the message, but had the option of opting out by pressing 9 - hopefully this works.

Caller ID says "Facebook". I don't know why they'd call me. I have never used it, and it is blacklisted in my firewall. I didn't answer, and they hung up on ring 4

My caller ID said it was Facebook as well. Highly doubt it, why would Facebook call any of their members. My guess its a scam hoping someone will answer just because caller ID said it was Facebook. This scammers are more bold every day. I never answer, unknown, private of toll free numbers.

3-28-16 got a call from this number. caller id only showed number on first line of caller and i second line it shows "V6505434800" which i beleive is an offshore usage of a usa number. no name shows, no msg left.. i believe it is a scam

According to other websites, this is NOT a facebook number. It's a scam. For me, it range 2 times and on the 3rd it hung up.

I live in Marlborough, Connecticut and received a random call from this number too. They didn't leave any messages, but I found out that their call back number is 1-855-770-7790 when I googled in their nonworking number 650-543-4800 which is only set up to dial out "Facebook" calls to customers randomly and will never be set up to leave any messages. If anyone ever gets any of these random "Facebook" calls upon this nonworking number 650-543-4800, I'd suggest that if you don't want to receive these unwanted calls like this, call back 1-855-770-7790 and tell this foreign company in Menlo, California to stop calling you!

I do have my own Facebook site, but I don't want to receive these calls from this foreign company in Menlo, California. Since their random number 650-543-4800 is not set up to receive calls, I've called them back on the other end of their company. Their call back number is once again, 1-855-770-7790 and told them I don't have any problems with my Facebook and don't want to receive these kind of calls like this again!
