- 2. (Optional) Toggle uniqueness or limit prefixes to mirror production ranges.
- 3. Click “Generate numbers”, copy or download the TXT file in one click.
Use cases
Where it helps
- • QA regression suites
- • Demo & sandbox datasets
- • Classroom or workshop exercises
- • Validating form logic, rate limits, or telecom API stubs
Best practices
- Mark every dataset as “test only” before sharing with stakeholders.
- Prefer E.164 format when integrating with telecom APIs or Supabase tables.
- Keep uniqueness ON for QA fixtures to avoid flaky assertions.
- Check local regulations before dialing or sending any SMS.
Mini FAQ
- Mini FAQ - Do you store my inputs?
- Everything runs locally in your browser session, so nothing leaves your device.
- Are these active phone numbers?
- They mimic valid formats but are not verified against carriers—treat them as fake test data.
- Can I send SMS or calls?
- No. Always rely on telecom-approved test ranges if you must send real traffic.
