âšī¸ About UUID Generator

â Frequently Asked Questions
UUID v4 is fully random, while UUID v7 embeds a Unix timestamp in the first 48 bits, making it time-sortable. UUID v7 is recommended for database primary keys and distributed systems.
A UUID has 122 random bits, giving roughly 5.3 x 10^36 possible values. The probability of collision is negligibly small for virtually any practical use case.
