UUID Generator FAQ
What is a UUID?
A UUID (universally unique identifier) is a 128-bit value used to label things uniquely, like database records, files, or API objects, with almost no chance of two being the same.
What is UUID version 4?
UUID v4 is the random version. Its digits are generated from secure random numbers, which makes it the most common choice when you just need a unique ID and do not need it tied to time or hardware.
Are these UUIDs truly unique?
UUID v4 has so many possible values that the chance of a collision is effectively zero for normal use. You can generate as many as you like without worrying about duplicates.
Can I generate many UUIDs at once?
Yes. Set the count up to 100 and generate them all in one click, then copy the whole list.
Do I need to sign up?
No. The UUID generator is free with no account and no limits.
