What does the DPP Compliance Checker verify?

It runs 8 checks per prEN 18222 and prEN 18246: Ed25519 signature validity, passportDataHash integrity, DPP code format, registry status, audit trail, ESPR Annex I fields, credential structure, and BitstringStatusList revocation. Iron and steel DPPs also get 10 CBAM-specific checks (BC1–BC10).

Is the DPP Compliance Checker free?

Yes — the checker is completely free, with no account required. You can verify up to 10 DPPs per day without an API key. Higher limits are available with a PassportLab API key.

What is a passing DPP compliance score?

A score of 8/8 means the DPP is fully compliant with ESPR and prEN 18222/18246. Scores of 6–7 indicate minor gaps. Scores below 6 signal material compliance failures that EU market surveillance authorities could flag.

What CBAM checks are included?

For iron, steel, and aluminium products, the checker runs 10 CBAM readiness checks (BC1–BC10): declarant number, importer EORI, embedded emissions value, production route, facility name, production country, CN code, heat/batch number, carbon price paid, and scope setting per CBAM Annex III.
