How it works
UUID v7 packs a 48-bit Unix millisecond timestamp into the first 12 hex digits, followed by 74 bits of random data plus version and variant bits.
Format: tttttttt-tttt-7xxx-yxxx-xxxxxxxxxxxx — where t is the timestamp and x is random.
Because the timestamp comes first, UUID v7 values sort chronologically — making them ideal for database primary keys, B-tree indexes, and event logs.
Defined in RFC 9562 (May 2024), v7 replaces older recommendations like ULID and KSUID for most use cases.
