A vanity number uses the standard alphanumeric mapping on a telephone keypad to spell a brand name, acronym, or memorable phrase. Businesses lease these toll-free or local numbers to increase customer recall in advertising. The underlying routing translates the letters back to the standard E.164 numeric format before the switch processes the call.
