Phoneword

Phonewords are numbers made up of digits and letters that spell out words. For example, the word "hello" can be spelled out using the phone number 4356356. When you dial this number on a phone, it says the word "hello" instead of just a string of numbers. Phonewords are a good way to remember a phone number more easily because it is easier to remember a word than a bunch of numbers.
