Frequently Asked Questions

Everything you need to know about our random phone number generator

No, these are randomly generated numbers for testing and placeholder purposes only. They are not real, active phone numbers and should never be used to contact actual people or services.

We support major international formats including US/Canada (+1), UK (+44), Australia (+61), Germany (+49), France (+33), India (+91), Japan (+81), Brazil (+55), and custom patterns that you can define yourself.

Yes! Select 'Custom Format' and use 'X' to represent digits in your pattern. For example, 'XXX-XXX-XXXX' would generate numbers like '555-123-4567'. All other characters will be preserved as-is.

This option ensures that each digit in the phone number is unique (no repeated digits). It's useful when you need more varied-looking numbers, though it's limited to patterns with 10 or fewer digit positions.

In many phone number systems, numbers don't start with zero as it often has special meaning (like for international dialing). This option ensures more realistic-looking phone numbers.

Absolutely not! These are fake numbers for testing and development only. Never attempt to call or text these numbers as they may belong to real people or services, which could cause problems.
