Frequently Asked Questions
A UUID (Universally Unique Identifier) is a 128-bit identifier that is practically unique across all space and time. The v4 variant generated here uses cryptographically random numbers. The format is 8-4-4-4-12 hexadecimal digits (e.g., 550e8400-e29b-41d4-a716-446655440000).
UUID and GUID (Globally Unique Identifier) are essentially the same thing. UUID is the standard term used in most contexts, while GUID is the term commonly used in Microsoft technologies.
v4 UUIDs have 122 random bits, giving approximately 5.3 x 10^36 possible values. The probability of generating a duplicate is astronomically small — you would need to generate about 2.7 x 10^18 UUIDs before having a 50% chance of collision.
Yes. Enter the number of UUIDs you want (up to 100) and click Generate. All UUIDs can be copied at once.
