UUID Generator FAQ
What is a UUID?
A 128-bit value designed to be unique across space and time without needing a central authority. It is commonly shown as 36 characters with 32 hex digits and 4 hyphens, for example 550e8400-e29b-41d4-a716-446655440000.
Which UUID version should I use?
The guide points to v7 for ordered IDs and better database indexing, v5 for deterministic IDs from stable input such as a URL or email, and v4 for a simple random ID when ordering does not matter.
