Random Test Data Generator
Chinese names / Phone numbers / Emails / ID card numbers / UUID
Use Cases
Useful for front-end mock data, database test-data seeding, API integration and UI prototype demos. The generated ID card numbers pass the checksum rules but match no real identity, and phone numbers use valid number segments. To generate random passwords, use the Password Generator.
FAQ
Are the generated ID card numbers real and valid?
The generated ID card numbers follow the GB 11643 checksum rule (the last digit is a weighted sum modulo of the first 17 digits), but they correspond to no real identity. They are for development testing, data seeding and UI display only, and must never be used in any scenario requiring real-name verification.
Is the generated test data safe? Is it uploaded?
All data is generated randomly in your browser and is never uploaded to any server, nor is any generated data recorded or stored. The whole flow is client-side, including the random algorithm and formatting, so the data stays secure.
How many records can be generated at most?
Up to 1000 records per run, supporting five data types: Chinese names, phone numbers (standard 1XX segments), emails, 18-digit ID card numbers and UUIDs (standard v4 format). The results are newline-separated and can be copied directly into Excel, database import scripts or code.
