Understanding UUIDs
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. Key features include:
- Uniqueness - Extremely low probability of duplicates
- Standardization - Follows RFC 4122 specification
- Portability - Works across all systems and platforms
- Security - Version 4 uses random or pseudo-random numbers
Common Use Cases
- Database primary keys
- Distributed systems
- Session IDs
- Transaction IDs
- File or document identifiers
Generator Features
- Version 4 UUID - Uses cryptographically strong random numbers
- Bulk Generation - Create multiple UUIDs at once
- Format Options - Copy as uppercase or lowercase
- Easy Copy - One-click copying to clipboard
- No Storage - Generated UUIDs are not stored or logged
Pro Tip:
Version 4 UUIDs are perfect for most applications due to their random nature. However, if you need time-based ordering, consider using Version 1 UUIDs instead. Our generator focuses on Version 4 for maximum security and uniqueness.
