How It Works
Our generator creates phone numbers following the North American Numbering Plan (NANP) format. Each number consists of a 3-digit area code (NPA), a 3-digit central office code (NXX), and a 4-digit line number.
When you select a specific state, the generator uses only real area codes assigned to that state, ensuring the numbers look authentic for testing purposes. The central office and line number portions are randomly generated.
Important: These phone numbers are generated for testing and development purposes only. They follow the correct format but are not guaranteed to be unassigned. Do not use them for any purpose other than testing.
