There are many web sites that will allow you to find out the status and phone company of a toll free number, but at Custom Toll Free® you can just tell us what number you wish to monitor and every month we will automatically send you the current information. Have a particular number that you really want? Get notified if a number becomes available, disconnected or changes phone companies. This service costs just $7.50 a month and can be updated or cancelled at any time.
