A vanity number is an easily remembered sequence of numbers used for marketing purposes, such as 1-800-PET-FOOD or 1-800-Go-FedEx. When you dial 1-800-PET-FOOD, you are calling 1-800-732-3663. Vanity numbers are not limited to toll-free numbers. You can have a vanity phone number with a local phone number too. If you had a local number of 509-555-3663, your vanity number would be 509-555-FOOD.
