What is a ULID?

A Universally Unique Lexicographically Sortable Identifier. 128 bits total: a 48-bit Unix-ms timestamp followed by 80 bits of randomness, encoded as 26 characters of Crockford Base32.

Why use one?

  • Sorts in insertion order — friendlier than UUIDv4 for database indices.
  • Case-insensitive, URL-safe, no separators.
  • Monotonic within a single millisecond when you use the monotonic mode.
