Around 1.33 M requests per day spread across 16 service endpoints. The cadastre alone queries ~757,000 times/day — at every land transaction with a legal entity the owner and representative chain is validated in the background. Master data is the invisible infrastructure of Estonia's e-government.

Estonian banks barely query the Business Register directly in Dec 2025 – May 2026. None of the large banks (Swedbank, SEB Pank, LHV, Luminor, Coop, Bigbank, Inbank, Citadele, Holm) appears as a notable arireg consumer — neither for master data, representation, compliance nor annual reports.
The banks are nonetheless major X-Road consumers — but they use other registers (population register, tax and enforcement IT, ID documents, consent management). They likely obtain corporate-customer representation data via upstream compliance providers or one-off onboarding.
