Telephone keypad

The development of the modernist telephone keypad is attributed to research in the 1950s by Richard Deininger under the directorship of John Karlin at the Human Factors Engineering Department of Bell Labs. The contemporary keypad is laid out in a rectangular array of twelve push buttons arranged as four rows and three columns of keys. For military applications, a fourth, right-most column of keys was added for priority signaling in the Autovon system in the 1960s. Initially, between 1963 and 1968, the keypads for civilian subscriber service had keys installed in only ten positions, omitting the lower left and lower right keys that commonly are assigned to the star (✻) and number sign (#) signals, respectively. These keys were added to provide signals for anticipated data entry purposes in business applications, but found use in Custom Calling Services (CLASS) features installed in electronic switching systems.


Phonewords are mnemonic phrases represented as alphanumeric equivalents of a telephone number. 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, but are subject to the constraint 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.
