Understanding UUID Collision Probability
The 128-bit UUID space contains 3.4 × 1038 possible combinations. To put this in perspective:
| Scenario | Probability |
|---|---|
| Single duplicate in 1 billion UUIDs | 1 in 2.71 quintillion |
| Hash collision before UUID collision | 1018 times more likely |
| Solar flare corrupting data | More probable |
Our generator implements RFC 4122 §4.4 algorithms to maintain these astronomical odds against collisions.

Technical FAQ
Version 4 provides maximum entropy while version 1 leaks MAC addresses. Modern security standards recommend against version 1 UUIDs except in specific hardware-based use cases.
While alternative ID systems have their uses, UUIDv4 remains the gold standard for:
- Universal database support
- No third-party dependencies
- Maximum collision resistance
