What is it?

Purpose-built fake data

Random Phone Number Generator synthesizes numbers that match real-world numbering plans so QA teams, engineers, and educators can populate forms, simulate onboarding journeys, and stress-test logic without exposing production contacts.

How to use

Three steps

  1. 1. Choose a country or Global mix, then set quantity and format.
  2. 2. (Optional) Toggle uniqueness or limit prefixes to mirror production ranges.
  3. 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.
