Vanity toll free numbers are a series of digits that spell something. The significance of this is to make your advertising dollars give you more bang for your buck. You lose a significant amount of your potential responses when you require clients to remember a series of unrelated random digits in order to be able to contact you.

The reason you advertise is to create a lasting impression on a potential client and repetition is the key. Consider running an ad campaign with the number 1-800-ORDER-NOW vs 1-800-492-7553 as the callback number. 1-800-ORDER-NOW will leave a much more memorable impression on a potential client. This means savings in your advertising budget by not needing as much repetition.
