In a nutshell, a ULID code is a combination of 48-bit time stamp (most significant part), with a millisecond accuracy, and a 80-bit random number (least significant part), totalling 128 bits, that is 16 bytes (octets).

The preferred (canonical) representation of a ULID is in a certain version of the Base32 encoding.
