DORA Register of Information — DNB filing guide (2026)
Firms supervised by De Nederlandsche Bank face one of the earliest mainland-EU Register of Information deadlines — and it is not 31 March. This guide covers the DNB date, the required format, and what to get right before you submit.
Filing deadline — DNB (Netherlands)
20 March 2026
The earliest mainland-EU deadline — 11 days before the headline 31 March date. The most common DNB planning mistake is assuming month-end.
Format required
EBA XBRL-CSV is required. A register in any other format is rejected before its contents are checked.
Reference date
31 December 2025 — the register reflects your ICT third-party arrangements as at year-end.
What DNB checks
- LEI checksums on every provider against GLEIF
- Cross-table referential integrity between the ESA templates
- Exit-strategy and audit-rights clauses on critical providers (Art 28(8), Art 30)
Common errors that get flagged
- Planning to the 31 March headline and missing 20 March
- Invalid or missing LEIs
- Incomplete fourth-party (subcontractor) chains
Who's in scope
- Banks, insurers and payment institutions under DNB supervision
- Other DNB-regulated financial entities in DORA scope
