UUID v4 Generator
The random UUID generator is a free online tool that creates version 4 UUIDs according to RFC 4122. UUID v4 are generated randomly and dynamically.
What is a UUID?
A Universally Unique Identifier (UUID) is a 128-bit number used to create unique values across different computers and at different times. UUIDs are useful when unique values are needed, for example, for primary keys to avoid duplicates. Due to their uniqueness, UUIDs are also useful for generating random test data or creating unique identifiers.
How Does UUID Work?
UUIDs use a 128-bit sequence of hexadecimal characters to ensure uniqueness. They consist of hexadecimal digits (0-9, A-F) and have the format XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX, with each hyphen separating segments. The final segment of the code indicates various aspects of the UUID, such as its version and encoding.
The random UUID generator allows you to create unique identifiers in a format that suits your needs. It can be used in situations where guaranteed uniqueness is required, such as in databases, object identification, or generating random data.
