About UUID Generator

UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. Our generator creates UUID v4, which are randomly generated and have an extremely low probability of collision.

UUID v4 Format:

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

  • 4 in the third group indicates UUID version 4
  • y is one of 8, 9, A, or B (variant indicator)
  • All other characters are random hexadecimal digits

Common Uses:

  • Database primary keys
  • Session identifiers
  • API request tracking
  • Distributed system node identification
  • File names for uploaded content
