DORA Register of Information: What It Is & How to Build It

DORA Register of Information What It Is & How to Build It

If you run technology or risk for a bank, insurer, investment firm, or payment institution in the EU, the DORA register of information is probably the single compliance artifact keeping your team up at night. It is the inventory of every ICT third-party arrangement your organization relies on, and it is now the first document national regulators pull when they open a supervisory file. Get it wrong — incomplete fields, mismatched contract data, an outdated exit strategy — and it becomes the fastest route to a formal enforcement letter. Get it right, and it becomes a genuine map of your operational risk. This guide explains what the register is, who has to file one, what belongs inside it, the 2026 deadlines, and a practical path to building (and maintaining) one, including where a compliance audit can shortcut the process.

What Is the DORA Register of Information?

The DORA register of information is a structured, continuously updated record of every contractual arrangement a financial entity has with ICT third-party service providers — cloud vendors, SaaS platforms, data centers, managed security providers, and any subcontractor that supports a critical or important business function. It is mandated under Article 28 of Regulation (EU) 2022/2554, better known as the Digital Operational Resilience Act (DORA).

The register exists to solve a specific supervisory problem: regulators previously had no system-wide view of how many banks and insurers were quietly dependent on the same handful of cloud and infrastructure providers. The register of information gives the European Supervisory Authorities (ESAs) and national competent authorities (NCAs) that visibility. It feeds three things directly:

1. Oversight of concentration risk — regulators can see when too much of the financial sector depends on one provider.

2. Designation of Critical ICT Third-Party Providers (CTPPs) — providers deemed systemically important come under direct ESA oversight.

3. Supervisory review of your own ICT risk management — an incomplete or inconsistent register is treated as a governance failure in itself.

Who Has to Maintain a DORA Register of Information?

DORA’s scope is deliberately broad. If your organization holds an EU financial services license, you are almost certainly in scope. That includes:

  • Credit institutions and payment institutions, including e-money institutions and account information service providers.
  • Investment firms, fund managers, and management companies operating under MiFID or the UCITS/AIFMD frameworks.
  • Insurance and reinsurance undertakings, including intermediaries above the small-entity thresholds.
  • Crypto-asset service providers and crowdfunding platforms brought into scope under DORA’s extended definitions.
  • Non-EU entities with an EU branch or subsidiary — DORA’s extraterritorial reach means a US or UK-headquartered firm with an EU license has the same obligation as a domestic one.

Critical ICT third-party providers themselves — including major cloud and hyperscaler platforms designated under the oversight framework — face a parallel but separate reporting regime supervised directly by the ESAs, as described by the European Banking Authority.

What’s Inside the Register: Templates and Mandatory Fields

This is where most teams underestimate the effort. The register of information isn’t a single spreadsheet under Commission Implementing Regulation (EU) 2024/2956, it’s a set of roughly 15 interconnected templates that must reconcile with each other before submission. Every ICT provider, contract, service line, and subcontractor needs its own record, cross-referenced by consistent identifiers.

Template areaWhat it captures
Entity & provider identityLegal Entity Identifier (LEI), country, provider type, and CTPP designation status for every direct ICT provider
Contractual arrangementsOne record per contract: counterparty, reference date, governing law, notice period, and criticality flag
Services & business functionsEach contract broken into individual ICT service lines, mapped to the business function each one supports
Sub-outsourcingMaterial subcontractors used by providers that deliver critical or important functions
Cost dataActual prior-year spend and estimated current-year cost per arrangement, reported in EUR
Criticality & exit strategyClassification of critical or important functions (CIF) and the documented exit plan for each one
What’s Inside the Register: Templates and Mandatory Fields

Once populated, the whole package is exported as an xBRL-CSV report — a table-oriented data format with an accompanying metadata file — using the taxonomy published by the ESAs. This is not a format most compliance or risk teams work with natively, which is why register-building is increasingly treated as a joint effort between compliance, procurement, and infrastructure engineering.

2026 Submission Deadlines (and What “Consolidated” Actually Means)

Financial entities don’t submit straight to the ESAs — they submit to their national competent authority first, which validates, consolidates, and forwards the data. Deadlines vary by country and sector, but they cluster tightly around Q1 2026:

Jurisdiction / sectorFinancial entity submission window (2026)
Netherlands (DNB)By 20–22 March 2026
Germany, France, Belgium, Ireland, Italy, SpainBy 31 March 2026
Luxembourg (CSSF, via eDesk)11 February – 31 March 2026
Insurance/reinsurance undertakings (e.g., CAA-supervised)By 1 March 2026
ESA consolidation deadline (all NCAs)31 March 2026
2026 Submission Deadlines (and What “Consolidated” Actually Means)

According to De Nederlandsche Bank, national competent authorities must forward their fully consolidated registers to the ESAs by 31 March of each calendar year — meaning your own internal submission window will close weeks earlier to give your NCA time to validate the file. Miss the internal deadline and you risk being flagged before the ESA even sees the data.

One detail teams frequently miss: the register isn’t a once-a-year exercise. Per ESMA’s DORA guidance, the underlying register must be kept continuously accurate — the annual submission is simply a snapshot of a system that should already be current.

Why the Register of Information Is the First Thing Regulators Check

Enforcement moved from “readiness checks” to active supervision in 2026, and Article 28 has become one of the two most frequently examined provisions (alongside Article 5 governance requirements). The financial exposure is real: material non-compliance carries fines of up to 2% of global annual turnover or EUR 10 million, whichever is higher, and individual board members can face personal liability of up to EUR 5,000,000 under national governance provisions. Designated critical providers face their own penalty track, including periodic payments of EUR 500,000 to EUR 5,000,000 per day.

In practice, national competent authorities are now cross-checking register of information data automatically against other regulatory filings. An incomplete provider record, a contract missing a termination notice period, or an exit strategy that was never actually tested tends to surface immediately — and has already become the leading cause of first-round supervisory letters.

How to Build a DORA Register of Information: A Step-by-Step Approach

Whether you’re starting from scratch or cleaning up a register assembled under deadline pressure last year, the same sequence applies:

  1. Inventory every ICT third-party arrangement — including shadow IT and SaaS tools procured outside central IT, which are the most common gaps.
  2. Classify which functions are “critical or important” (CIF) — this classification determines how much detail each contract needs and whether sub-outsourcing has to be tracked.
  3. Standardize provider identity data — obtain and validate LEIs for every direct provider; inconsistent identifiers are one of the most common reconciliation failures between templates.
  4. Map contracts to the ITS template structure — decompose each contract into individual service lines and link each to the business function it supports.
  5. Trace sub-outsourcing chains for any provider supporting a critical function, down to material subcontractors.
  6. Document (and actually test) exit strategies for every critical arrangement — a written plan that has never been rehearsed is a common audit finding.
  7. Convert to xBRL-CSV and validate against the ESA taxonomy before your NCA’s internal deadline, then establish an owner and a quarterly review cadence so the register never goes stale between annual submissions.

Most of this work is less about compliance paperwork and more about infrastructure visibility — knowing exactly which cloud accounts, environments, and vendors sit behind each business function. Teams that already have clean infrastructure documentation from an IT audit typically move through steps 1–4 in a fraction of the time.

Common mistakes that trigger regulator follow-up

Most register problems trace back to a handful of recurring habits. Teams treat the register as a one-time export instead of a living record tied to procurement and vendor-management workflows, so it drifts out of date within weeks of submission. Subcontractors one or two levels down the chain get missed for critical functions, because nobody owns visibility that deep into a provider’s own vendor stack. Exit strategies exist on paper but were never operationally validated, which surfaces the moment an auditor asks for evidence of a test run. And inconsistent LEIs or provider names across templates quietly break the automated cross-checks an NCA runs the moment the file lands.

How Gart Solutions Helps You Get (and Stay) DORA-Ready

Building an accurate DORA register of information is fundamentally an infrastructure and vendor-visibility problem before it’s a paperwork problem — you can’t document dependencies you haven’t fully mapped.

Gart Solutions works with fintech, insurance, and payments teams on exactly that groundwork:

  • Compliance audits that map every ICT vendor, contract, and subcontractor against DORA’s Article 28 requirements before you build the register.
  • Infrastructure audits that surface shadow IT and undocumented cloud dependencies — the most common source of register gaps.
  • SRE and disaster-recovery engineering to design and actually test the exit strategies your critical-function contracts require.
  • Fractional CTO support for teams that need senior technical ownership of the register-building process without adding full-time headcount.

FAQ

What is the DORA register of information?

It's the mandatory inventory, under Article 28 of the Digital Operational Resilience Act, of every ICT third-party arrangement a financial entity relies on — covering providers, contracts, services, subcontractors, and exit strategies. It gives national regulators and the ESAs system-wide visibility into ICT concentration risk.

Who needs to submit a DORA register of information?

Nearly every EU-licensed financial entity: banks, payment and e-money institutions, investment firms, fund managers, insurers and reinsurers, and crypto-asset service providers, plus non-EU firms operating through an EU branch or subsidiary.

When is the DORA register of information deadline in 2026?

Deadlines are set by national competent authorities and cluster around Q1 2026 — for example, 1 March for some insurance regimes and 31 March for most banking-sector filings — with the ESAs' own consolidation deadline set at 31 March 2026.

What format is the DORA register of information submitted in?

It's submitted as an xBRL-CSV report package — a table-oriented data file plus metadata — built against the ESA-published taxonomy, not as a standard spreadsheet export.

Why does the register of information matter so much to regulators?

It's become the primary enforcement trigger under DORA. National competent authorities cross-check register data automatically, and incomplete or inconsistent registers are the leading cause of supervisory follow-up letters in the first enforcement cycle.

How do you build a DORA register of information from scratch?

Start with a full inventory of ICT third-party arrangements, classify which support critical or important functions, standardize provider identifiers (LEIs), map contracts to the ITS templates, trace sub-outsourcing chains, and document and test exit strategies before converting the data to xBRL-CSV.

How often does the DORA register of information need to be updated?

Continuously. The annual submission is just a snapshot of a register that regulators expect to be accurate year-round, not a document assembled once under deadline pressure.
