Number Generator
Format-valid numbers for a selected country — right dial code, right national length. Built for test fixtures and pipeline sampling, generated locally in your browser.
Free number tools
Four free utilities that run entirely in your browser — no signup, nothing uploaded. When you need live platform data, the bulk checker takes over.
Number Validator (E.164)
Validate a list against its country numbering plan and normalize every surviving row to E.164 — with counts for valid, invalid and duplicate rows.
List Cleaner
Paste or upload any list — numbers, emails, IDs — and get it back deduplicated and stripped of blank lines, original order preserved.
Number Lookup
Paste one international number to see its country (from the dial code), its E.164 form, and — where the plan is pinned — whether the national length is plausible.
