What this proves

The checker verifies syntax and the mathematical check digit. It can detect many mistyped or structurally invalid identifiers.

What it does not prove

A mathematically valid ISIN is not proof that the identifier was actually issued, remains active, or belongs to a particular security. Those questions require authoritative reference data.

NO IDENTIFIER IS SENT TO BONDSTATS OR A THIRD-PARTY API.
