these vanity phone numbers are widely used in USA
They are special phone numbers that spell out a word or phrase instead of having a series of numerals. For example, you could have a phone number that spells out "1-800-FLOWERS" instead of the regular number 1-800-356-9377. These vanity phone numbers are designed to be easier to remember and to help businesses stand out from the competition. Vanity phone numbers are also sometimes referred to as toll-free or 800 numbers, and they are typically available through telephone service providers.
