GUID Generator

Generate Globally Unique Identifiers (GUIDs)

Our GUID Generator tool creates standard, random 128-bit identifiers. These GUIDs (also known as UUIDs) are widely used for creating unique identifiers in various applications and systems.

What is a GUID?

A GUID (Globally Unique Identifier) is a 128-bit number used to identify information in computer systems. GUIDs are typically represented as 32 hexadecimal digits, displayed in five groups separated by hyphens, in the form 8-4-4-4-12 for a total of 36 characters.

GUID Structure

Our GUIDs follow the standard structure:

  • 8 hexadecimal digits
  • 4 hexadecimal digits
  • 4 hexadecimal digits (first digit is always '4', indicating version 4 UUID)
  • 4 hexadecimal digits
  • 12 hexadecimal digits

Use Cases for GUIDs

  • Database Keys: As primary keys in databases to ensure uniqueness across distributed systems.
  • Session IDs: For tracking user sessions in web applications.
  • Transaction IDs: To uniquely identify transactions in financial systems.
  • File Names: To create unique file names in storage systems.
  • Component Identification: In software development to identify components or modules.
  • Network Protocols: In various network protocols that require unique identifiers.
