Numbers that pass the check.

No, these numbers are randomly generated and do not belong to any real person or service. They cannot receive calls or messages.

Very realistic. Numbers follow each country's actual numbering plan, including valid area codes, carrier prefixes, and correct digit lengths.

No limits. Generate as many numbers as you need, in any format, for any supported country.

Copy the whole list, or download it as TXT, CSV or JSON. The JSON keeps each number in all the formats at once, which is usually what a fixture file wants.

Yes — set a seed and the same seed gives the same list every time. That is what makes a generated fixture reproducible instead of a new surprise on every test run.

That is the point of the default mode: every number is checked against libphonenumber before you see it. There is also a mode that deliberately produces invalid numbers, for testing the path where validation fails.
