Fake phone number generator

Phone numbers that match a locale's number pattern, for form validation and layout tests, with no live/dead claim anywhere.
LocaleRows (1- 50 )Lock seedNew seedevery press draws a fresh seed: the result shows itHow it works

- Numbers are pattern draws: no carrier, assignment, or live/dead check exists here (a real check would be a lookup this tool refuses).
- A generated number can collide with a real assigned one; never send anything to a generated number.
- Nothing persists: rows live in this tab only, and no request leaves the page. The generator runs in a Web Worker, so the locale data never loads into the page itself.
- Names come from @faker-js/faker's locale pools, and every run records its seed.

- Ten numbers, en_US, seed 42

US layout with extensions sometimes appended

- Five numbers, pl, seed 7

Polish mobile pattern

- Five numbers, ja, seed 2026

Japanese hyphen-grouped pattern
