What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. The probability of generating duplicate UUIDs is so low that it's considered negligible.

Common Uses for UUIDs:

  • Database primary keys and record identifiers
  • Session identifiers in web applications
  • File names for uploaded content
  • Transaction IDs in payment systems
  • Device identifiers in IoT applications

Format Example:

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

Where x is any hexadecimal digit and y is one of 8, 9, A, or B
