Frequently Asked Questions

Are these real phone numbers?
No. They are randomly generated to look like valid US numbers for software testing and demos. They are not assigned to anyone, so never use them to contact people.
What is the format of the numbers?
US style: a three-digit area code, a three-digit exchange, and a four-digit line number. You can show them with parentheses, dashes, as plain digits, or in +1 international form.
Can I generate many at once?
Yes. Set the count up to 50 and copy the whole list, which is handy for seeding a test database or filling a demo.
