Overview

​
Identifiers

Collect two identifiers from each business customer in Turkey and submit them as strings on the application body. Tax ID: 10-digit numeric; issued to all legal entities at tax office registration; appears on Vergi Levhası and official GİB portal. Registration number: 16-digit numeric; unique permanent company identifier assigned at incorporation; replaces earlier trade registry number for digital transactions.

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: Issued by affiliated chamber via MERSIS; includes MERSIS No. and registration details.
  • Constitutive Documents: Filed with and published in the Türkiye Ticaret Sicili Gazetesi (TTSG).
  • Tax Registration: GİB-issued; shows VKN (10-digit), entity type, and tax-office assignment.
  • Operating Permit: Municipal permit; required before operations commence; renewed periodically.
  • Sector-Specific License: Required only for regulated sectors; fintech/e-money requires TCMB payment institution license.
  • Governance Records: Current governing persons appear in MERSIS extract and Gazette publication.
  • Signing Authority: İmza Sirküleri is the standard bank/counterparty authorization artifact; board/manager resolution for specific transactions.
  • 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: Turkey is a subsumed-by-extract jurisdiction: the dated Ticaret Sicil Tasdiknamesi issued via MERSIS serves as proof of current good standing; no separate certificate of good standing is issued by a distinct authority.

​
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.

Notes

  • MERSIS vs. Trade Registry Number: older documents may show a legacy Ticaret Sicil Numarası (chamber-specific numeric). The MERSIS No. (16-digit) is the current universal identifier and is what GİB, banks, and customs require. Always collect the MERSIS No.
  • İmza Sirküleri is mandatory: Turkish banks and counterparties universally require the notarized İmza Sirküleri listing authorized signatories with specimen signatures. A resolution without a Sirküleri is typically insufficient.
  • Apostille Convention: Turkey is a Contracting Party to the Hague Apostille Convention (ratified; in force 29-IX-1985; e-Apostille system live at eapostil.gov.tr since 2019). Foreign documents destined for Turkish use and Turkish documents for foreign use can be apostilled rather than requiring full consular legalization.
