Collection notes
- Legal Registration: Downloadable from prh.fi or ytj.fi; confirms Y-tunnus, registered office, entity type, governing bodies, status; available in Finnish, Swedish, or English.
- Constitutive Documents: Filed with PRH at incorporation; retrievable via prh.fi document service; Ay/Ky uses a partnership agreement (yhtiösopimus) instead of articles.
- Tax Registration: Confirms Y-tunnus and registration status in VAT, prepayment, and employer registers; printable via MyTax (vero.fi); VAT number = FI + 8-digit Y-tunnus.
- Sector-Specific License: Required for credit institutions (Laki luottolaitostoiminnasta 610/2014 §4), payment institutions and e-money institutions (Laki maksulaitoksista 297/2010), investment firms, insurance companies; licence register at finanssivalvonta.fi.

- Signing Authority: Signing authority (nimenkirjoitusoikeus) is registered in Trade Register; prokura grants broad commercial authority (Kauppakaari/Commercial Code); board resolution required for non-routine acts.
- Address: Conduit universal policy: lease (no time bound) OR utility bill OR bank statement, with utility/bank dated within 90 days. Same evidence satisfies both registered-address and operating-address checks.

Notes
- Single identifier: Y-tunnus serves as both the registry number and the corporate tax ID — collect one certificate; both
businessInfo.taxIdandbusinessInfo.businessEntityIdtake the same value. - Osakasluettelo is not public and not filed with PRH. The internal share register (OYL 624/2006 Ch. 3 §15) is maintained by the company itself; PRH does not hold it. For KYB, request the Edunsaajarekisteri extract from PRH plus a company-certified copy of the osakasluettelo directly from the entity.
- Edunsaajarekisteri access requires legitimate-interest registration. Post-CJEU WM/Sovim (2022-11-22), general public access was restricted; Conduit as a regulated obliged entity must register with PRH and pay per-extract fees (€30) or hold an annual contract; access not automatic.
- Oy minimum share capital was abolished 2019-07-01 (OYL amendment eff. 2019-07-01). Pre-2019 documents will show €2,500 minimum; this is no longer required. Do not reject entities with €0 registered capital.
- Bilingual registry: extracts in Finnish/Swedish/English. Finland is constitutionally bilingual; Trade Register extracts and articles of association may be in Finnish or Swedish — request an English extract via PRH’s order service if needed for downstream review.
- From 2026, all Trade Register notifications must be filed electronically (PRH mandatory online-only filing from 2026-01-01); paper-based historical filings still retrievable via PRH document order service.
