What is a UUID?
UUID stands for Universally Unique Identifier. It is a standardized identifier commonly used to identify records, objects, sessions, resources and other entities in software applications.
A UUID is typically represented as a 36-character string containing hexadecimal characters and hyphens.
UUID Example
Example UUID

UUIDs are commonly displayed in five groups of hexadecimal characters separated by hyphens.
UUID Version 4
This generator uses the browser's crypto.randomUUID() API, which generates a random UUID following the UUID Version 4 format.
UUID Version 4 values are generated using random data rather than being derived from a name, timestamp or network address.
When should you use a UUID?
- Generate unique identifiers for database records.
- Create identifiers for application objects or resources.
- Generate request or session identifiers.
- Create identifiers for distributed systems.
- Generate test data during development.
UUID vs Sequential IDs
Is my UUID data uploaded to a server?
No. UUID generation is performed directly in your browser using the Web Crypto API. The generated UUIDs do not need to be sent to a backend server.
Generation Limit
This tool allows you to generate between 1 and 100 UUIDs at a time. Generating multiple UUIDs at once can be useful when preparing test data or development fixtures.
