What format are these UUIDs?

Standard UUID v4 — 36-character strings including hyphens, generated using cryptographically secure randomness.

Are these guaranteed to be unique?

UUID v4 has such a vast number of possible values that collisions are astronomically unlikely in practice.

Run the generator multiple times — each batch of up to 100 is generated fresh.
