Who it's for

CRM and marketing ops: normalize numbers to E.164 before importing or sending SMS.
Sign-up forms and lead lists: catch typos and fake numbers like 12345.
Sales teams: separate mobile from landline numbers.
Developers and AI agents: one call, consistent JSON.

Input

Phone numbers: one per line, in any common format.
Or a CSV link (for example a Google Sheet published as CSV). Every phone-looking cell is used.
Default country (optional): for numbers written without +country code, like 020 7946 0958 with GB.

}

result	meaning
`valid`	Right length and in a number range that's in use for that country.
`possible`	Right length, but in a range not assigned (yet). Often a typo.
`invalid`	Wrong length, unknown country code, or not a number.

A SUMMARY record in the key-value store counts each result and the duplicates.

Pricing

You pay per number checked. See the Pricing tab.

Limits, honestly

"Valid" means the number fits the country's official numbering plan. It does not mean the line is active or who owns it. Checking that needs a carrier lookup, which this tool doesn't do.
Some countries don't separate mobile and landline ranges (the US and Canada, for example). Those numbers show landline_or_mobile.
Numbers keep moving between carriers, so the carrier isn't reported.
We process only the numbers you send and don't store or reuse them.
