With our free online UUID v4 generator, you can quickly and easily create universally unique identifiers with just one click. UUID v4 (Universally Unique Identifier version 4) is a standard alphanumeric code consisting of 36 characters, including letters, numbers, and hyphens, as specified by RFC 4122. This standard ensures the uniqueness of the generated identifiers, which are essential for various technology applications. The tool also allows generating multiple UUIDs at once, ideal for batch testing, populating databases, and initializing distributed systems.
What is UUID v4?
UUID v4 is a universally unique identifier that uses random numbers to ensure that each code is exclusive. It follows this format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx.
What is a UUID used for?
UUIDs are widely used to ensure uniqueness in data identification, mainly in software development for the unique identification of records and objects; in databases as distributed primary keys; in distributed systems for synchronization and tracking between servers; in REST APIs for resource identification; in microservices for transaction monitoring; in IoT devices for hardware identification; and in web sessions for user control and authentication.
How to use our tool
To use our UUID v4 generation tool, simply click the 'Generate UUID' button; the system will immediately create a unique UUID v4 code that you can copy and use in your projects. To generate multiple UUIDs at once, check the 'Generate Multiple UUIDs' option and select the desired quantity (from 2 to 100 UUIDs). All generated UUIDs can be copied individually or all at once.
