What is a GUID?

A GUID is a Globally Unique Identifier, also known as UUID. It is a 128-bit value used to uniquely identify records, database entries, devices, sessions, and application resources across distributed systems.

This GUID generator tool creates unique identifiers that are safe for use in web apps, APIs, cloud services, and enterprise workflows.

Why use GUIDs?

GUIDs help prevent collisions when multiple systems generate IDs independently. They are especially useful for databases, data synchronization, transaction tracking, and any application that requires globally unique identifiers.

Supported GUID versions

This tool supports UUID version 4 and version 7 generation. UUID v4 uses random data for uniqueness, while UUID v7 is time-ordered for better indexing and sorting in databases.

How to use this GUID generator

Enter the number of GUIDs you need, choose the UUID version, and optionally enable formatting options such as hyphens, braces, uppercase, quotes, or commas. Then click Generate GUID/UUID to copy or download your identifiers.
