Vanity number

Vanity Numbers
A toll-free vanity number, custom toll-free number, or mnemonic is easy to remember; it spells and means something or it contains an easily recognized numeric pattern.
A vanity number is a local or toll-free telephone number for which a subscriber requests an easily remembered sequence of numbers for marketing purposes.

RespOrg

responsible organizationResponsible Organizations (Resp Orgs)
In the United States, Federal Communications Commission regulations mandate that numbers be allocated on a first come, first served basis; this gives vanity number operators who register as RespOrgs a strong advantage in obtaining the most valuable phonewords, as they have first access to newly disconnected numbers and to newly introduced toll-free area codes. North American toll-free numbers are controlled by an intelligent network database (SMS/800) in which any toll-free number may be directed to a local or long-distance geographic telephone number, a T-carrier or primary rate interface line under the control of any of various RespOrgs.
In the North American Numbering Plan, a RespOrg (a contraction for responsible organization) is a company that maintains the registration for individual toll-free telephone numbers in the distributed Service Management System/800 database.

Zenith number

Examples of operator-assisted toll-free calling include the Zenith number introduced in the 1950s in the U.S. and Canada, as well as the original manual 'Freephone' service introduced by the British Post Office in 1960.
The service preceded the system of toll-free telephone numbers with area code 800 in the United States.

Toll-free number portability

number portabilityported to any carrier
The practice is nonetheless potentially problematic as it leaves local businesses advertising numbers which they do not own and for which they therefore have no number portability.
Toll-free number portability (Canada, US, New Zealand) or freephone number portability (Australia, UK) allows the subscriber of a freephone number to switch providers while retaining the same number for incoming calls.

Phoneword

mnemonicPhonewordsletters
In toll-free telephony, a shared-use number is a vanity number (usually a valuable generic phone word), which is rented to multiple local companies in the same line of business in different cities.
Toll-free telephone numbers are often branded using phonewords; some firms use easily memorable vanity telephone numbers like 1-800 Contacts, 1-800-Flowers, 1-866-RING-RING, or 1-800-GOT-JUNK? as brands for flagship products or names for entire companies.

Automatic number identification

ANIautomatic number identification (ANI)the caller's number
Toll free numbers usually capture the telephone number of the caller for billing purposes through automatic number identification, which is independent of caller ID data and functions even if caller ID is blocked. The system initially provided no support for Automatic Number Identification and no itemised record of calls, instead requiring subscribers to obtain expensive fixed-rate lines which included some number of hours of inbound calling from a "band" of one or several U.S. states or Canadian provinces.
Modern toll-free telephone numbers, which generate itemized billing of all calls received instead of relying on the special fixed-rate trunks of the Bell System's original Inward WATS service, depend on ANI to track inbound calls to numbers in special area codes such as +1-800, 888, 877, 866, 855, 844 with 833 and 822 reserved for future toll free use (United States and Canada), 1800 (Australia) or 0800 and 0808 (United Kingdom).

Area codeTelephone codearea codes
A toll-free, Freecall, Freephone, 800, 0800 or 1800 number is identified by a dialing prefix similar to a geographic area code, such as 909 (the area code that covers eastern Los Angeles County and southwestern San Bernardino County).
