About ULID

ULID (Universally Unique Lexicographically Sortable Identifier) is designed to be a better UUID.

Sortable

The leading characters are encoded from a timestamp, so ULIDs generated later sort after those generated earlier.

URL Safe

Uses Crockford's Base32 alphabet for better readability and URL safety.

No Collisions

Includes 80 bits of randomness to ensure uniqueness even within the same millisecond.
