Are these generated phone numbers callable in the real world?

No. AddrGen strictly uses national regulatory reserved fictitious ranges (such as the North American NANP 555-0100 to 555-0199 fictitious numbers, UK Ofcom 01632 / 020 7946 drama ranges, and Australian ACMA test blocks). These numbers are permanently reserved and will never ring a real person or business.

Do these test phone numbers conform to the ITU-T E.164 format?

Yes. Every generated number adheres strictly to the International Telecommunication Union (ITU-T) E.164 recommendation, correctly combining country calling codes (+1, +44, +49, +81), national area codes, and subscriber numbers up to the maximum 15-digit limit.

Can I test SMS notification workflows with these numbers?

These numbers are intended for client-side form validation, regex parsing, and sandbox API tests (such as Twilio Test Credentials). Because they are non-callable and non-deliverable, they cannot receive real SMS text messages.

How do area codes match the generated address?

Every phone number is paired with its corresponding state or city geographic anchor. For example, a generated Chicago address will carry an authentic 312 or 773 area code, while an Atlanta address will use 404 or 770.
