Background
A toll-free phone number is a number beginning with 800, 855, 866, 877 or 888 instead of a geographic area code. If you have been given a toll-free number, and a hearing person calls you through a Video Relay Service (VRS) or IP Relay Service using that toll-free number, he is not charged for his phone call to the Relay Service. (Deaf users who call you directly are never charged for their call, whether they call you using your local number or toll-free number.)
On August 4, 2011, the FCC adopted new rules to promote the use of geographically appropriate local telephone numbers, while ensuring that the deaf and hard-of-hearing community has access to toll-free telephone numbers that is equivalent to the access enjoyed by the hearing community. These rules went into effect on November 22, 2011, and allow for a one year transition period that will end on November 21, 2012.
