Phone Number Generator

1. Pick a state, or leave it random.
2. Set how many numbers you need and choose a format.
3. Generate and copy the result.

A US phone number has three parts: a three-digit area code, a three-digit exchange and a four-digit line number.

The area codes used here are genuine and mapped to their states, so a number generated for California carries an area code actually in use there. That makes the result plausible for testing regional logic.

The exchange and line digits are drawn at random within valid ranges — neither may begin with 0 or 1, a rule inherited from the original dialling system.

The result is a number that looks and validates like a real one without being tied to any subscriber.

Numbers in the 555-0100 to 555-0199 range are formally reserved for fiction, which is why they appear in films and television.

They are useful when a number must be visibly fake to a human reader — documentation, screenshots, marketing mockups.

They are less useful for testing validation logic, because some systems specifically reject them. For that, a plausible number with a real area code exercises the code path better.

It queries no carrier or registry. There is no line, subscriber or service behind the number.

Because the digits are drawn at random within valid ranges, a generated number may coincide with someone’s real line. Never call or text a number produced here.

Use it for form validation, seed data and interface mockups.
