random phone number generator

How to use the random phone number generator

  1. Pick a country from the dropdown — US, UK, CA, AU, IN, DE, or FR.
  2. Choose a format: E.164 (+1234567890), national (regionally formatted), or pretty (dashes and spaces).
  3. Set the count, between 1 and 500, for how many numbers to generate at once.
  4. Click Generate. Copy any individual number or use 'Copy all' to paste the batch into a CSV or seed file.

When to use it

Use it when seeding development databases, populating UI mockups, testing phone-number form validation, or demoing CRM features with realistic-looking data. Never use the output for live contact — these numbers may route to real subscribers. For payment-gateway testing, prefer Stripe/Paddle test phone numbers from their documentation instead. Alternative: faker.js does the same in code, but this tool is faster for one-off batches and doesn't require a JavaScript project.

Frequently asked questions

Are these real phone numbers?
No — they're random digits that conform to each country's numbering format. Some of them may, by coincidence, belong to real subscribers. Never call, text, or publish them.
Can I use these for account verification or SMS testing?
No. Real SMS gateways will attempt delivery and you risk reaching real people. For SMS testing, use a dedicated sandbox number from Twilio, Vonage, or your SMS provider.
What countries does the random phone number generator support?
United States, Canada, United Kingdom (mobile), Australia (mobile), India (mobile), Germany (mobile), and France (mobile).
What format should I use for database seeding?
E.164 (`+14155552671`) is the safest format for database columns — it's unambiguous, sortable, and accepted by every phone library including libphonenumber.
Are the 555 numbers excluded in US mode?
Yes. The US generator filters out area codes and exchanges that are entirely 555, since those are reserved for fictional use and commonly flagged as invalid by validators.
Are the numbers cryptographically random?
Generation uses `crypto.getRandomValues`. Randomness isn't usually a security-sensitive property for test data, but the quality is good enough for statistical distribution across area codes.
