This Toll Free Prefixes List is Kept Up-To-Date


This toll free prefixes list is current and kept updated as new prefixes are released. All toll free number prefixes (800, 888, 877, 866, 855, 844, 833, 822 etc.) are regulated and function the same way as the original 800 number prefix released in 1963. Although often referred to as prefixes, technically these 3-digit numbers are area codes as part of the North American Numbering Plan (NANP).

However, unlike local dial zone area codes, toll free area codes are setup so callers do not pay long distance fees when calling over traditional landlines. They also give businesses a national presence since they do not represent a specific region in North America. Moreover, the FCC has put in special toll free number portability rules that protect business owners who use the numbers by ensuring that businesses can easily move their toll free number from one phone company to another without service interruption. That is why even today, toll free numbers are the preferred business phone numbers of small and large companies alike. You may get toll free numbers with all of the above listed toll free prefixes from FCC authorized toll free service providers such as UniTel Voice.
