Custom Toll Free Search API

Custom Toll Free's toll free number search has the ability to return vanities using an English language dictionary and an algorithm to rank the results and return the top vanity matches.

When a search term is entered, Custom Toll Free attempts to match that term with as many other words that make logical sense to create full vanities (all words as opposed to a mix of words and numbers). Studies have found that full vanities are much easier to remember and our search algorithm is designed to optimize the results based on numbers that are memorable. The tool will also search all prefixes (800, 866, 877 and 888) to determine the best match as there are few true 800 numbers currently available.
