This is a number that is given by a company that peruses singles dating sites. It is to make you think that a real girl is responding to a post or ad in a singles site. Ultimately it will end up sending you to a website that will require a payment for the persons info. But you will never actually find the person because they do not exist. Kind of like a make believe prostitute. The number is real but no one will ever answer the phone, but they will text you back with a website address.
