About UUID Generator
UUID Generator creates version 4 (random) UUIDs — 128-bit identifiers commonly used as unique keys in databases and distributed systems, where collisions between independently generated IDs need to be effectively impossible.
Common Use Cases
- Generating a primary key or unique identifier for a new database record.
- Creating placeholder IDs for testing or seed data.
- Generating a batch of unique tokens or reference codes at once.
Frequently Asked Questions
What does 'v4' mean?
UUID version 4 means the ID is generated primarily from random numbers, as opposed to other UUID versions that incorporate timestamps or hardware identifiers. It's the most common version for general-purpose unique IDs.
