How to Verify a Company in Türkiye

Before engaging in cross-border business, it is essential to verify the legal existence of your potential Turkish partner. Company verification in Türkiye means confirming that the entity is officially registered with the government and legally permitted to conduct business.

This guide explains how international buyers can use official Turkish registries to verify basic corporate information.

What You Can Verify Publicly

Using official Turkish state and statutory portals, you can generally confirm:

• The legal name of the company.
• The company’s Tax Identification Number (Vergi Kimlik Numarası - VKN) or MERSİS number.
• The registered headquarters address.
• The current operational status (e.g., active or liquidated).

What You May Not Be Able to Verify Publicly

Without a Turkish citizen identity number (TC Kimlik) and access to the authenticated e-Devlet (e-Government) portal, international users cannot easily access:

• The complete historical list of board members and shareholders.
• Detailed financial statements or tax debt status.
• Internal corporate restructuring documents.

Step-by-Step Verification Workflow

1. Request Official Documentation

Always ask the supplier for their foundational documents before you attempt a public search. Specifically, ask for:

• Vergi Levhası (Tax Registration Certificate): Contains their Tax ID (VKN) and Tax Office.
• Ticaret Sicil Gazetesi (Trade Registry Gazette publication): Shows their official establishment.
• Faaliyet Belgesi (Certificate of Activity): Issued by the local Chamber of Commerce, proving they are currently active.

2. Search MERSİS (Central Registration System)

MERSİS is the Ministry of Trade’s central database. You can perform a basic search on mersis.ticaret.gov.tr using the company name or MERSİS number to confirm the company exists and matches the documents you were given.

3. Check the Trade Registry Gazette

Go to ticaretsicil.gov.tr. While viewing detailed PDFs requires a free account registration, you can search the index to ensure the company has a legitimate trail of official announcements (like address changes or board appointments).

4. Verify Tax Registration

If you have the company’s VKN and their registered Tax Office (Vergi Dairesi), you can use the Revenue Administration’s (GİB) Interactive Tax Office portal (ivd.gib.gov.tr) to query the validity of their tax plate (e-Vergi Levhası).

Warning Signs

During your verification, watch out for these red flags:

• The company name on the proforma invoice does not perfectly match the name in MERSİS.
• The supplier refuses to provide a Vergi Levhası or claims they “do not need one for exports.”
• The registered address points to a virtual office or residential apartment when they claim to own a massive factory.
• The MERSİS status is listed as “Terkin” (Liquidated) or “Tasfiye Halinde” (In Liquidation).

What Verification Cannot Guarantee

Finding a company in an official registry does not guarantee that the company is a safe business partner. Registration proves legal existence; it does not prove:

• Creditworthiness or financial health.
• Manufacturing capability. A registered “trade company” might outsource 100% of its production.
• Product quality or export compliance.

When Local Assistance May Be Useful

If you are dealing with a high-value order or face language barriers navigating Turkish official and registry sites, you may need a local professional (such as a Turkish lawyer, accountant, or commercial investigator) to pull full authenticated records via e-Devlet and perform physical site visits.
