About GUIDs
What is a GUID?
A GUID (Globally Unique Identifier) is a 128-bit number used to uniquely identify information. GUIDs are the Microsoft implementation of UUIDs (Universally Unique Identifiers) and are widely used in Windows and .NET applications.
GUID vs UUID
GUIDs and UUIDs are essentially the same thing. The term "GUID" is primarily used in Microsoft technologies, while "UUID" is the standard term used in most other contexts. Both follow the RFC 4122 specification.
Features
- 128-bit unique identifier
- Version 4 (random generation)
- Multiple output formats
- Bulk generation support
- Platform-specific formats (C#, SQL)
Generate random GUIDs (Globally Unique Identifiers) for .NET applications, SQL Server, Windows development, and COM objects. GUIDs are functionally identical to UUIDs but are the preferred term in Microsoft ecosystems.
