What is a UUID v4?

UUID v4 is a randomly generated UUID that uses a cryptographically secure random number generator. It is the most popular UUID version for general use. A UUID v4 is made up of 122 random bits, with 6 bits reserved for version and variant information. This makes collisions extremely unlikely, even at very high volumes. UUID v4s are ideal for cases where you need a unique identifier that does not reveal any information about the time or place of creation. They are widely used for database keys, session tokens, and anywhere a unique, opaque ID is needed.

Format

UUID v4 consists of random or pseudo-random numbers, with version 4 and variant bits set

xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

Common Use Cases

  • Session IDs
