Phonewords are mnemonic phrases represented as alphanumeric equivalents of a telephone number.^[1] In many countries, the digits on the telephone keypad also have letters assigned. By replacing the digits of a telephone number with the corresponding letters, it is sometimes possible to form a whole or partial word, an acronym, abbreviation, or some other alphanumeric combination.

Phonewords are the most common vanity numbers, although a few all-numeric vanity phone numbers are used. 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.

Local numbers are also occasionally used, such as +1-514-AUTOBUS or STM-INFO to reach the Société de transport de Montréal,^[2] but are constrained by the fact that the first few digits are tied to a geographic location, potentially limiting the available choices based on which telephone exchanges serve a local area.
