UUID Generator
Cryptographically-random UUIDs (version 4) generated with the Web Crypto API — the same source production systems use. Export as CSV or copy individually.
Test data only. Everything on this page is randomly generated for software testing, QA, education and design. It does not belong to real people, accounts or devices. Never use generated data to register on services, deceive anyone or commit fraud — that is illegal.
How it works
- 01
Pick a country (and gender where available) so data follows the local format — names, streets, postal patterns and phone prefixes.
- 02
Hit Generate. Every value is produced in your browser with the correct checksum algorithm where one exists.
- 03
Copy any field, a whole section or everything at once — or export the batch as JSON / CSV.

Primary keys, request IDs, distributed identifiers — anywhere you need unique labels without central coordination.
