Frequently Asked Questions
What is UUID v7?
UUID v7 is a time-ordered UUID format (RFC 9562) that encodes a Unix timestamp in the first 48 bits, making UUIDs sortable by creation time.
UUID v4 vs v7 — which to use?
Use UUID v7 when you need time-ordered sorting (e.g., database indexes). Use UUID v4 when you need purely random identifiers with no time information.
Is UUID v7 a standard?
Yes, UUID v7 is defined in RFC 9562 (2024). It is the recommended UUID version for new applications due to its time-sorting capability.
