What is Vanity number?

  • Also called: vanity phone number, memorable number

Reviewed by Sujan ThapaliyaLast updated

Definition

A vanity number spells a word or forms a memorable pattern on the keypad, so it can be recalled without being written down. Most are toll-free, because the value is in advertising a number people will remember hours later.
The three STIR/SHAKEN attestation levels, which underpin how vanity number behaves in practice: A asserts both that the carrier knows the customer and that the customer may use the calling number, B asserts the customer only, and C asserts neither. A shared number pool can reach B at best, which is why number ownership keeps recurring in these definitions.
Attestation is the backdrop to most caller-ID and deliverability terms, vanity number included.

In practice

How vanity number actually works

Their value is entirely a function of the medium. On radio, outdoor and vehicle livery, where nobody can copy a number down, a memorable one is worth paying for. In a digital campaign where the number is a tap target, it is decoration.

Availability drives the cost. Good words on the original toll-free prefix are effectively gone and trade at a premium, while the same word on a newer prefix is often free.

The mechanics matter more than the word: a vanity number still needs routing, hours and someone answering, and an unanswered memorable number is remembered for the wrong reason.

Worked example

On a van or a radio ad, where nobody can write the number down, a memorable one earns its premium. On a web page where the number is a tap target, it is decoration.

Vanity number: common questions

Are vanity numbers still worth it?
In media where the audience cannot write the number down — radio, outdoor, vehicles — yes. Where the number is clickable, the memorability is worth very little.
Do vanity numbers have to be toll-free?
No, local vanity numbers exist and can work well for regional businesses. Toll-free is more common because national advertising is where memorability pays.
How much does a vanity number cost?
It depends entirely on the word and the prefix. A common word on the original toll-free prefix commands a premium in the secondary market; the same pattern on a newer prefix is often available at the standard rate.

See vanity number in the product

A toll-free number is one the called business pays for rather than the caller. In North America they use the prefixes 800, 833, 844, 855, 866, 877 and 888, which are functionally identical — the newer ones exist only because the older ones ran out. They signal national reach; a local number signals proximity.
