How do I verify my Facebook account if the phone number they have is old?

The phone number I have listed on Facebook account is old and outdated. Recently they said I had some unusual activity and made me "verify" my account. First they gave me pictures of friends -- which was impossible because the pictures they had me identify were not even people, some were posters or baby pictures but my friends were tagged. So then they said that they would send an text to my phone but the phone number is old. Am I screwed?

It doesn't even sound like Facebook. There is a such virus explained as "Malware calls home" and i believe that they want your number to give you malware calls home.
