Description

USA Dizhi is a free Address Format Lab for generating fictional United States addresses and related test data. It produces street, city, state abbreviation, and ZIP layouts that match common US writing order, plus sample names, phones, and other fields kept at typical lengths so forms and layouts can be checked without using real personal data.

Sensitive numbers are generated at common field lengths but are designed to fail checksums. Emails and phones cannot receive mail or pass verification, and the samples are not for real payments, shipping, or identity checks. Developers can copy a full address, generate by city, or browse state and city format pages.

The lab also covers address order notes for Apt, Ste, and Unit lines, ZIP versus ZIP+4 structure, and billing versus shipping field separation. Use it only for format learning and software testing in development environments.
