THE BASICS
What Is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier used to distinguish resources, records, and objects across systems.
A standard UUID is represented as a 36-character string containing hexadecimal characters and hyphens.
Example UUID: 550e8400-e29b-41d4-a716-446655440000
UUIDs are commonly used in software development, databases, APIs, distributed systems, and applications where unique identifiers are needed.
THE BASICS
What Is UUID Version 4?
UUID Version 4 is generated using random or pseudorandom values. It is one of the most commonly used UUID versions because it does not require a central authority or timestamp to generate an identifier.
A Version 4 UUID contains randomly generated bits along with specific version and variant bits defined by the UUID standard.
Although collisions are extremely unlikely, UUIDs are not mathematically guaranteed to be unique.

GOOD TO KNOW
A few things, answered.
Quick answers about this tool.
A UUID is a 128-bit identifier used to uniquely identify resources, records, and objects across software systems.
UUID and GUID generally refer to the same 128-bit identifier format. GUID is a term commonly used in Microsoft technologies.
UUID Version 4 is a randomly generated UUID that uses random or pseudorandom values along with standard version and variant bits.
No UUID system provides an absolute mathematical guarantee of uniqueness. However, the probability of collisions with properly generated Version 4 UUIDs is extremely low.
You can generate multiple UUIDs in one operation. The available quantity depends on the maximum limit configured in the tool.
Yes. Use the output formatting option to remove hyphens from generated UUIDs.
Yes. You can choose uppercase or lowercase output without changing the underlying UUID value.
Yes. MoSanKit's UUID generator is free to use without registration.
If generation runs entirely in your browser, UUIDs do not need to be transmitted to or stored on a server.
