Reserved, not real

State-aware area codes
The area code comes from a real state list; the rest of the number stays in the reserved block.

Phone number questions
- It produces numbers in the 555-0100 to 555-0199 range. That block is reserved for fictional use in US film, television, and test data. It is not a working phone number.
- No. This tool does not connect to a carrier, receive messages, or provide OTP codes. Using phone numbers to bypass verification is prohibited and is a legal risk in many jurisdictions.
- The area code is chosen from a list of real area codes associated with the selected state, while the exchange and line number stay in the reserved fictional range. This makes the number look plausible without being dialable.
- Only as an obvious test fixture. Label it as synthetic, keep it out of customer-facing records, and never use it where a real phone number is required for identity or delivery.
- Yes. Every field has a copy button, including the national format and the E.164 format such as +14155550123.
