Where is DPP data stored? Decentralisation, registry and blockchain

The EU registry stores identifiers, not passports. And no, you don't need blockchain.

Key takeaways

  • ●The central registry (deadline 19 July 2026) holds identifiers; passport data stays with operators or providers.
  • ●Decentralised does not mean you must run your own servers.
  • ●Blockchain is optional, never a legal requirement.

Registry vs passport

ESPR Article 13 required a central registry by 19 July 2026, operated under Implementing Regulation (EU) 2026/1778. It stores at least the unique identifiers so customs and authorities can check products. The substantive passport data is hosted by the responsible operator or a DPP service provider.

Backups and continuity

Article 11 requires passports to remain available, including a backup copy held by an independent DPP service provider, so data survives if a company goes out of business.

Interoperability standards

  • CEN/CENELEC JTC 24 — EN 18216, 18219–18223:2026 for identifiers, carriers, access, APIs and exchange
  • GS1 EPCIS 2.0 — lifecycle events in JSON/JSON-LD with REST interfaces
  • W3C Verifiable Credentials — proving who issued a claim
  • UN Transparency Protocol (UNECE Rec. 49) — global traceability framework
