Checks the format instantly — no official registry lookup exists publicly, so that part can't be automated honestly.
Most artists never need to generate their own ISRC or UPC — DistroKid assigns real, valid ones for free the moment you upload your music.
An ISRC identifies one specific recording; a UPC identifies a whole release (single, EP or album). This tool checks the format is well-formed (and, for UPC, that the check digit is mathematically correct) — it can't tell you whether a code is actually registered anywhere, since no public database exists for that.

Most artists don't — your distributor assigns valid ones for free when you upload your release. Only labels or high-volume artists who want to own their codes typically buy a registrant prefix directly.
An ISRC identifies one specific recording (a single song). A UPC identifies an entire release — a single, EP or album — as a sellable product.
