The eko24.net UUID Generator creates random UUID version 4 identifiers instantly in your browser. UUIDs are widely used by developers when an application needs unique values for database records, API resources, test data, sessions, distributed systems and other software objects. You can generate a new identifier with one click and copy it immediately without installing software or creating an account.
What is a UUID?
UUID stands for Universally Unique Identifier. It is a 128-bit identifier normally displayed as hexadecimal characters in five groups separated by hyphens. A UUID can be created independently without asking a central service for the next available number, which makes this format useful for applications that create data across different devices, servers or services.
What is UUID version 4?
UUID v4 uses random values to create identifiers. A typical UUID v4 follows the familiar 8-4-4-4-12 character grouping. Because the available identifier space is extremely large, UUIDs are commonly used when developers need practical uniqueness without maintaining a sequential counter.

Common uses for UUIDs
Developers use UUIDs in many situations, including database primary keys, API object identifiers, development fixtures, test records, distributed applications and temporary resources. They can also be useful when sequential numeric IDs are inconvenient or when multiple systems need to create identifiers independently.
