Best Phone Numbers provides many phone numbers that use repetition (like 312-888-8888, one of the vanity numbers currently available) or spell out the name of a company. Customers consist largely of attorneys, car dealerships, limousine and taxi companies, insurance companies and ad agencies

In fact, according to a 2007 study by Creative Broadcast Concepts (CBC) Inc., radio ads that featured vanity phone numbers attracted 58% more calls than ads with regular phone numbers, clearly demonstrating the effectiveness of a memorable phone number.

Though BestPhoneNumbers.com also licenses 1-800 numbers, Ferdinand feels there is a growing movement toward local numbers, as people become more frustrated with calling customer service centers overseas.
