Phonewords are mnemonic phrases represented as alphanumeric equivalents of a telephone number. In many countries, there exist letters corresponding to each digit on a telephone keypad. The letters corresponding to a particular telephone number can form a word, a partial word, an acronym, abbreviation, or an alphanumeric combination; these are known as phonewords. 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, 1-800-FREE-411 or 1-800-GOT-JUNK? or 1-800-BATTERY? 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,〔http://www.stm.info/en/info/customer-service/contact-us〕 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. == Advantages == The main advantages of phonewords over standard phone numbers include increased memorability and increased response rates to advertising. They are easier to remember than numeric phone numbers; therefore when businesses use them as a direct response tool in their advertising (radio, television, print, outdoor, etc.), they are proven to increase response rates by 30-60%. Regular side by side testing of phonewords and phone numbers in TV and radio advertising in Australia has shown that phonewords generate up to twice as many calls as standard phone numbers. A study conducted by Roy Morgan Research in February 2006 indicated that 92% of Australians are aware of alphanumeric dialling. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phoneword」の詳細全文を読む スポンサード リンク
