UUID Generator

Generate UUIDs (Universally Unique Identifiers)

Number of UUIDs (1-100)

1. What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information. They are commonly used in distributed systems and databases.

2. How does it work?

UUID v4 (Random)

Version 4 UUIDs are randomly generated. The probability of generating duplicate UUIDs is extremely low - approximately 1 in 5.3×10³⁶ (5.3 undecillion).

Format

UUIDs are typically displayed as 32 hexadecimal digits, displayed in 5 groups separated by hyphens: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

3. Examples

Example UUID v4
