Use our free UUID Generator to generate universally unique identifiers (UUIDs) for your applications. Generate UUID v4 (random) and UUID v1 (timestamp) identifiers instantly.

Perfect for developers who need unique IDs for databases, records, sessions, or any application requiring unique identifiers.

What is a UUID?

UUID (Universally Unique Identifier) is a 128-bit identifier that is practically guaranteed to be unique. UUIDs are commonly used in software development for:

  • Database Records: Unique primary keys
  • Session IDs: User session identifiers
  • Distributed Systems: Unique IDs across systems
  • File Names: Unique file identifiers

UUID Versions

Our generator supports multiple UUID versions:

  • UUID v4: Randomly generated (most common)
  • UUID v1: Timestamp-based
  • UUID v5: Name-based (SHA-1)

How to Use the UUID Generator

Generating UUIDs is simple:

  1. Select the UUID version (v4 is recommended)
  2. Choose the number of UUIDs to generate
  3. Click "Generate"
  4. Copy the generated UUIDs

A UUID has the format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
