Overview

​
Identifiers

Collect two identifiers from each business customer in Spain and submit them as strings on the application body. Tax ID: The NIF is the universal entity identifier; also the registry reference for Registro Mercantil extracts. The número de hoja mercantil (sheet number in provincial register) is a secondary locator. Registration number: The NIF is the universal entity identifier; also the registry reference for Registro Mercantil extracts. The número de hoja mercantil (sheet number in provincial register) is a secondary locator.

How documents combine

For each evidence area, this table shows whether the listed documents are alternatives (any one of) or a bundle (all required). The artifact-by-artifact lookup follows below.

​
Documents to collect

The physical documents you’ll collect from your customer, with the evidence area each one proves. One document can prove multiple areas — for example, Brazil’s Cartão CNPJ covers both tax and business-registration proof, so it appears once with both areas listed.

Collection notes

  • Legal Registration: Obtain via sede.registradores.org. Nota simple is informational; Certificación is evidentiary. Provincial register for domicile; RMC for name/denomination index.
  • Constitutive Documents: Paired: notarial deed (escritura) + statutes (estatutos). Both inscribed in the Registro Mercantil; confirmed by BORME publication.
  • Tax Registration: Issued after Form 036 filing. NIF is provisional until notarial deed + Registro Mercantil inscription are provided. Definitive NIF confirmation letter from AEAT is the artifact to collect.
  • Operating Permit: Issued by the ayuntamiento (town hall) of the premises municipality. Name varies by municipality; same substantive requirement.
  • Sector-Specific License: Required only for regulated-sector customers.
  • Governance Records: Administrator appointments inscribed in provincial Registro Mercantil; confirmed in extract.
  • Signing Authority: Notarized POA most common. Board/members’ meeting minutes (acta) with express grant of authority also accepted.
  • 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.
  • Good Standing: Order via sede.registradores.org from the provincial Registro Mercantil where the company is domiciled. The Certificación (evidentiary) is the formal good-standing instrument and confirms the company is legally constituted, not dissolved, and free of registry-recorded restrictions. The Nota Simple is informational and reflects register state at time of issue but is not evidentiary. Banks typically require issuance within 30 days; cross-border use commonly 60-90 days.

​
Person roles

When you submit a person on the application body, set their role to one of Conduit’s canonical BusinessPersonRole values. Use this table to map a local corporate-governance title onto the right canonical role.

Additional fields

Country-specific fields you’ll need to collect during onboarding, beyond the document uploads.

Notes

  • Single identifier: NIF serves as both the registry number and the corporate tax ID — collect one certificate; both businessInfo.taxId and businessInfo.businessEntityId take the same value.
  • The NIF is both the tax ID and the primary registry identifier — there is no separate “company registration number” distinct from the NIF in Spanish practice. Collect the NIF; it unlocks both the AEAT census record and the Registro Mercantil extract.
  • Nota simple vs. Certificación: a nota simple is informational and lacks evidentiary value for legal or judicial purposes. For binding KYB use, request a certificación registral (signed by the registrar). The sede.registradores.org portal issues either form digitally.
  • S.L. minimum capital of €1 (Ley 18/2022, eff. 2022-10-19): companies capitalized below €3,000 must reserve 20% of annual profits until capital + reserve = €3,000; partners bear joint and several liability for the shortfall in liquidation. Flag this risk tier in onboarding.
