How do vanity numbers work?

Each letter stands for the key it is printed on (2 ABC through 9 WXYZ). The network only sees digits, so 1-800-FLOWERS is routed exactly like 1-800-356-9377.

How do you dial a vanity number?

Press the key that shows each letter: for 1-800-FLOWERS dial 1, 8, 0, 0, then 3-5-6-9-3-7-7. Or paste it into the converter above and dial the digits it gives you.

How much do vanity numbers cost?

It depends on the provider; the toll-free registry doesn't publish one retail price, and the FCC prohibits selling toll-free numbers for a fee outside competitive bidding. Compare providers' monthly and setup charges.

Are vanity numbers worth it?

That depends on how people find you: a number that spells your service helps on radio, billboards and vehicles, where people must remember it. Print the digits too, since not every keypad shows letters.

What is my phone number in words?

Enter it under Number to words above. The tool lists every English word its last seven digits spell, whole or in part. Many numbers spell nothing useful, especially ones with 0 or 1, which have no letters.

Can this tool tell me if a vanity number is available?

No. It converts between letters and digits only. Availability for toll-free numbers comes from a RespOrg searching the toll-free registry.

Vanity number converter: phone number to words, and words to digits

A vanity number is a phone number that spells a word on the keypad, like 1-800-FLOWERS (1-800-356-9377). To convert one, type it with its letters and this tool replaces each letter with its key: 2 ABC, 3 DEF, 4 GHI, 5 JKL, 6 MNO, 7 PQRS, 8 TUV, 9 WXYZ. Enter digits instead to see which words a phone number spells.

How do I convert a vanity number to digits, or a number to words?

To dial a vanity number, type it with its letters, such as 1-800-CONTACTS, under Letters to number. The digits appear as you type.
To find words in a number, type the digits under Number to words and press Find words.
Read the list: whole-word spellings come first, then two-word splits and partial words, with how many digits each word covers.
Copy the digits for your listings and print them beside the word, so people with keypads that lack letters can still dial.

Example

You enter: 1-800-555-HELP under Letters to number.
You get: It dials as 1-800-555-4357 (digits 18005554357). Going the other way, Number to words lists word spellings of the digits, up to 60 matches.
Limits: No usage limit and no account; Number to words shows up to 60 spellings per number.

What is a vanity number?

A vanity number is a phone number whose digits spell a word or phrase on the letters printed on a phone keypad, so it is easier to remember: 1-800-FLOWERS, 1-800-CONTACTS. The letters themselves are never dialled; each stands for the key it sits on. The words are also called phonewords; Wikipedia's Phoneword article covers their history.

Toll-free numbers are the classic vanity numbers, since a number people call from anywhere gains most from being easy to remember, but any number can spell a word. The same keypad letters let a caller dial it, and phones with on-screen keypads show the letters on the dialpad, as the Phoneword article notes.

How do you convert letters to numbers on a phone?

Replace each letter with the key it is printed on: 2 ABC, 3 DEF, 4 GHI, 5 JKL, 6 MNO, 7 PQRS, 8 TUV, 9 WXYZ, with nothing on 1 and 0. That is the layout in ITU-T Recommendation E.161, the international standard for keypad letters. FLOWERS becomes 356-9377: F is on 3, L on 5, O on 6 and so on.

In North America a number is ten digits after the 1, so a word longer than seven letters runs past the end of the number: in 1-800-MATTRESS the final S is an eleventh digit and not part of the number. Whether a call still connects when someone dials it depends on their phone and network, so list the plain digits too. The converter flags any extra letters.

How do I find what words my phone number spells?

Enter the number under Number to words. Each digit from 2 to 9 stands for three or four letters, so seven digits have up to 4^7 = 16,384 spellings; the tool generates them against an English word list and keeps only real words. For a North American number it looks at the last seven digits, the part you would choose when picking a number, and also shows words in part of the number, such as 1-800-356-YES-7.

The word list is built from SCOWL, a public word list used by spell checkers, limited to common words of 3 to 10 letters, with offensive words removed using the LDNOOBW list. It loads only when you press Find words and the search runs in your browser.

How do I get a vanity phone number?

For a toll-free vanity number, ask a toll-free service provider, known as a Responsible Organization or RespOrg, to search for and reserve it. Somos, the administrator of the US toll-free registry, offers a search for numbers and for providers and says reservations go through its certified toll-free service providers. For a local vanity number, your phone provider decides what it can offer from the numbers it holds.

Don't plan on buying one from a broker. Under the FCC's rule 47 CFR 52.107, toll-free subscribers may not hoard numbers, and no one may acquire a toll-free number to sell it for a fee, apart from numbers assigned by competitive bidding. This tool only shows spellings; it can't tell you whether a number is free, taken or in service.

Can I convert a vanity number in Excel or Google Sheets?

Who uses this tool, and for what?

Small businesses: Check which words a number you've been offered spells before you print it on vans, signs and ads.
Marketing teams: Shortlist memorable spellings for a toll-free number, then hand the digits to your provider to search.
Call centers: Convert a client's vanity number to digits for IVR routing tables, CRM records and E.164 formatting.
Callers: Turn 1-800-SOMETHING from an ad into digits you can dial on a keypad or paste into a phone app.

What can’t this tool tell you?

It never checks availability, ownership or whether a number is in service; it only converts spellings.
The word list is English and deliberately modest; brand names, slang and other languages won't appear.
Letters on 0 and 1 don't exist, so numbers with those digits spell fewer words, and I or O can be misdialled as 1 or 0.
Some older keypads placed Q and Z differently or left them out; modern phones follow E.161.

The numbering plan only knows what a range was issued for.

In the US and Canada mobiles and landlines share the same prefixes, and anywhere a number can be ported or reassigned the range stops telling the whole story. A live carrier lookup asks the network data instead, which is what the Email + Phone plan adds.
