UUIDs remain a standard identifier strategy across languages and storage systems. Version selection matters because behavior differs across random, time-ordered, and namespace-driven formats.
This page is optimized for utility: pick a version, generate values, and continue implementation with consistent identifier output.
Choose UUID version based on operational behavior, not trend alone: random for broad uniqueness, time-ordered variants for index-friendly patterns.
