At Aancall, we specialize in providing USA toll-free numbers to help businesses connect with their customers. But how exactly do these numbers work, and what are the rules surrounding them? Here is everything you need to know.
What Is a Toll-Free Number? 800, 888, 877, 866, 855, 844, 833?
A toll-free number utilizes a distinct three-digit code that can be dialed from landlines at no cost to the person placing the call. These numbers allow callers to reach businesses and individuals outside of their local area without incurring long-distance fees.
While they are the standard for customer service—providing a free and convenient way to contact businesses—there is an exception for mobile phones. Wireless callers will be charged for airtime minutes used during a toll-free call unless they have an "unlimited calling" plan.
Texting Capabilities
Businesses can also send texts in response.
The Official USA Toll-Free Codes
Toll-free numbers begin with one of the following three-digit prefixes:
800
888
877
866
855
844
833
Important Note: Although these are all toll-free codes, they are not interchangeable. Dialing a number with a 1-800 prefix will reach a different recipient than dialing that same number with a 1-888 prefix. Calls to each specific number are routed to a unique local telephone number.
What Is a "Vanity" Number?
A "vanity" number is a toll-free telephone number that spells out a name, word, or acronym chosen by the subscriber. Famous examples include 1-800-FLOWERS or 1-888-NEW-CARS.
How Are These Numbers Assigned?
The FCC assigns most toll-free numbers on a first-come, first-served basis.
To get a number, subscribers must choose a "Responsible Organization" (known as a RespOrg).
RespOrgs reserve numbers on your behalf and manage the appropriate records.
Many RespOrgs, like Aancall, also provide the actual toll-free service.
RespOrgs have access to the toll-free database, which tracks the status of all numbers.
Somos, Inc. administers this database and certifies the RespOrgs.
The 833 Auction Experiment The FCC has made certain numbers in the 833 code available via an auction. This is an experiment to determine if competitive bidding is a more effective way to assign numbers.
If you need help locating a RespOrg, you can call or text the Somos Help Desk at 1-844-HEY SOMOS (1-844-439-7666) or visit www.somos.com/find-a-toll-free-number.
The Role of the FCC
The FCC sets the rules for acquiring and using these numbers. Most importantly, the FCC requires portability. This means a subscriber can "port" (move) their number to a new RespOrg if they decide to change service providers.
However, the FCC:
Is not involved in the actual assignment of numbers.
Cannot access the number database.
Cannot provide information about the status of a specific number.
Rules: Warehousing, Hoarding, and Brokering
To maintain fairness, the FCC enforces strict prohibitions against misuse.
Warehousing (RespOrgs): RespOrgs are prohibited from "warehousing" numbers. They cannot legally reserve a toll-free number without having an actual subscriber ready to use it. Violators are subject to penalties.
Hoarding (Subscribers): Subscribers are prohibited from "hoarding." You may not acquire more toll-free numbers than you intend to use.
Brokering: Hoarding includes the illegal practice of "number brokering"—selling or offering to sell a toll-free number.
