Secure UUID & GUID Bulk Generator

UUID / GUID Generator

Bulk generate RFC-compliant UUID tokens instantly. Support for v4 (random), v1 (timestamp/node), and v7 (database ordered). 100% offline-ready.

💡 How It Works

UUID Generator creates unique identifiers used in databases, APIs, and distributed systems. Generate single or bulk UUIDs in v4 (random), v1 (timestamp), or v7 (sortable) versions. Export as text, JSON, or copy directly.

Example: v4 UUID: 550e8400-e29b-41d4-a716-446655440000 | Generate 100 at once | Export to JSON

Understanding UUID & GUID Versions

A Universally Unique Identifier (UUID) is a 128-bit label used for database primary keys, session identification, transaction tracking. Microsoft refers to this standard as a Globally Unique Identifier (GUID).

Differences Between v4, v7, and v1

UUID v4: Constructed fully out of cryptographically strong random values. This is the most common UUID form.
UUID v7: Incorporates a Unix millisecond timestamp at the beginning, followed by random entropy. This time-ordering makes it highly optimized for relational databases (like PostgreSQL, MySQL) to prevent index fragmentation.
UUID v1: Generated from the exact host computer system timestamp and physical MAC node.
