Not exactly, They can be sorted, by default, only down to a millisecond, but you can use a monotonic generator to have them sorted, even if more than one Ulid is generated within a millisecond. Other than that, they have 80 bits of randomness, enough to be unique even if millions are generated per second. https://github.com/ulid/spec https://github.com/ulid/spec
