Question 1

Are these real addresses?

Accepted Answer

The cities, regions and postcodes are real, and the formatting matches what each country's postal service expects — that is what makes the data useful for testing an address form. The street numbers and names are generic inventions, and the combination as a whole is not a real delivery point. Treat it as plausible-looking test data, not as somewhere a parcel will arrive.

Question 2

Why does the phone number matter so much here?

Accepted Answer

Because randomly assembled digits usually belong to somebody. Test data has a habit of escaping into demos, screenshots, seeded databases and published tutorials, and the person on the other end starts getting calls. Every number this tool produces comes from a block that a telecom regulator has formally set aside for fiction and will not allocate to any provider, so there is nobody on the other end to disturb.

Question 3

Why is there no phone number for Japan?

Accepted Answer

Because Japan does not have an officially reserved fictitious range. Countries like the US, UK, Australia, Germany and France have all designated blocks that will never be assigned; Japan's Ministry of Internal Affairs and Communications has not. Inventing a Japanese-looking number would break the one guarantee this tool is built on, so the field is left empty instead.

Question 4

Why are the email addresses always @example.com?

Accepted Answer

RFC 2606 reserves example.com, example.org and example.net precisely so they can be used in documentation and testing. They are permanently unregistrable, so mail sent to them cannot reach a real inbox. It is the same principle as the reserved phone ranges.

Question 5

Can I generate a whole list at once?

Accepted Answer

Yes — set a count under "Generate in bulk" and export the result as CSV. The file is written with a UTF-8 byte order mark so that Excel opens accented and Japanese characters correctly instead of showing them as garbled text.
