Why use our US phone number generator
A US phone number is a 3-digit area code plus a 7-digit local number. The generator follows the North American Numbering Plan and checks every number, so each random US phone number comes out valid and safe for tests.
Need data for New York, Los Angeles, Houston, Dallas, Chicago or Atlanta? They all use their own real area codes, and the generator picks the right ones for realistic US test data.

Frequently asked questions
Are these valid US phone numbers?
Yes. Each US phone number is checked against the United States numbering plan, so the area code and number format hold up.
Are these fake or real numbers?
They are valid in format but belong to nobody. Think of them as safe fake numbers for testing, not for real calls.
What is a US area code?
It is the first 3 digits of the number, and it tells you the region. 212 means New York, 312 means Chicago, and so on.
Can these numbers receive SMS or calls?
No, random numbers cannot receive SMS or calls. If you need a working number, try our free temporary number service.
