Frequently Asked Questions

What is the difference between UUID v4 and v7?
UUID v4 is randomly generated. UUID v7 includes a timestamp prefix for time-ordering, improving database index performance.
Can two UUIDs ever be identical?
Theoretically possible but practically impossible. UUID v4 has 2^122 possible values — the probability of collision is astronomically low.
Can I generate multiple UUIDs at once?
Yes! Our generator supports bulk UUID creation. You can generate multiple UUIDs simultaneously and copy them all with a single click, perfect for database seeding and testing.
