Choose a numbering plan
Each generator follows a country-specific display pattern. Where a safe fictional range is known, the tool uses it; otherwise, it keeps potentially identifying digits masked.
Built for test data
A phone field should be easy to test without borrowing a real person's number. Number Foundry produces predictable examples for common development and design tasks.
UI mockups
Fill realistic layouts without placing real contact details in screenshots or prototypes.
QA fixtures
Export batches to CSV for repeatable test records and import scenarios.
How safety is built in
Useful test data should look plausible without quietly becoming someone else's contact information. The generator applies a different safety rule to each numbering plan.
- 01
Select the numbering plan
Country-specific punctuation, trunk prefixes and international codes shape each result.
- 02
Apply a safe range
Known fictional ranges are used for the US, Canada and UK. Potentially identifying digits in other countries remain masked.

Questions, answered
The boundary is simple: this tool creates sample data. It does not provide active numbers, SMS inboxes or ways around account verification.
Is this a fake phone number generator?
It generates fictional or masked phone-number samples for tests, examples and interface mockups. It does not supply active subscriber numbers or pretend that the samples can be contacted.
Can these numbers receive calls or verification codes?
No. Number Foundry does not provide telephony, SMS inboxes or account-verification services.
Can I use the samples in automated tests?
Yes. You can copy a batch or download a CSV for test fixtures. Keep validation behavior separate from any workflow that contacts real people.
Why are some countries shown with X characters?
When a generally accepted fictional range is not asserted, masking part of the number preserves a useful display format without risking a real subscriber number.
