Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. The standard representation is 32 hexadecimal digits displayed in 5 groups separated by hyphens.
What is UUID v4?
UUID v4 is generated using random numbers. The version is indicated by the digit in the 13th position (4) and the variant is indicated by the digit in the 17th position.
Are generated UUIDs truly unique?
While not mathematically guaranteed unique, the probability of a collision is extremely low (1 in 2^122). You would need to generate 1 billion UUIDs per second for 85 years to have a 50% chance of one collision.
