Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value formatted as 36 characters, e.g., 550e8400-e29b-41d4-a716-446655440000.
Are these UUIDs truly unique?
UUID v4 uses random numbers, making collisions extremely unlikely (practically zero for most applications).
Can I generate multiple UUIDs?
Yes. Set the count to generate up to 50 UUIDs at once, with a one-click copy for each or all.
Is this UUID v4?
Yes. Generated IDs follow RFC 4122 version 4 format using cryptographically secure random values.
