How to search the MERSIS
- 1
Log in to MERSIS
Access the MERSIS portal using the 'e-Devlet' (e-Government) login or a specific user account for the Central Registration System.
- 2
Select Inquiry Type
Navigate to 'Sorgular' (Inquiries) and choose whether to search by company name (Ünvan), MERSIS number, or tax number (Vergi No).
- 3
Verify Legal Entity Status
Check the company's current status (Aktif/Pasif) and legal form within the search results page.
- 4
Access Gazette Records
For detailed historical changes (directors, capital, address), cross-reference finding with the 'Türkiye Ticaret Sicili Gazetesi' (Trade Registry Gazette).
Who uses this data
KYC/AML compliance officers investigating Turkish subsidiaries, local law firms verifying signatory authorities, and supply chain auditors tracking company registrations across different provinces.
Access, fees & notes
MERSIS provides a centralized view, but detailed corporate history and resolutions are often best found in the Trade Registry Gazette (Ticaret Sicili Gazetesi), which requires a separate free registration.
Cost & access
Basic entity registration and inquiry are free with an e-Devlet account. Official certificates and certified documents usually require fees payable via the system.

Common mistakes to avoid
✗ Using a search engine without a login and finding only generic results.
✓ Full search features and entity details require logging in via e-Devlet or a MERSIS account.
✗ Confusing the MERSIS number with the Tax ID (VKN).
✓ While they are linked, the MERSIS number is a 16-digit identifier starting with the VKN, followed by 000 and ending with a sequence number.
Frequently Asked Questions
What is a Ltd. Şti.?▾
Ltd. Şti. (Limited Şirketi) is Turkey's limited liability company. Minimum capital is TRY 10,000. It requires 1-50 shareholders and is the most popular company form for small and medium businesses.
What is an A.Ş.?▾
A.Ş. (Anonim Şirketi) is Turkey's joint-stock company, equivalent to an AG or SA. Minimum capital is TRY 50,000 (TRY 100,000 for registered capital system). Required for certain regulated sectors like banking and insurance.
How do I search MERSIS?▾
MERSIS (mersis.gtb.gov.tr) provides company search in Turkish. You can search by company name, tax number, or MERSIS number. Basic data is freely accessible.
What is Turkey's tax number system?▾
Every Turkish business receives a Vergi Kimlik Numarası (tax identification number) — a 10-digit number for companies. It's distinct from the MERSIS number and is used for all tax transactions.
How do I search for a company in Turkey by name?▾
Type the company name into the search box above. Results come from the official Turkey register and show the registered name, registration number, status and registered address. Partial names work — searching "acme" returns every registered entity whose name starts with it.
Is the Turkey company register free to search?▾
Yes. Searching by company name or registration number is free here and on the official Turkey register — no account or payment is required for a basic lookup. Certified extracts and filed documents may carry a fee on the official register.
Can I search Turkey companies by registration number?▾
Yes. Enter the registration number instead of the name and the lookup resolves it directly to the matching record, which is the fastest way to confirm an identifier printed on an invoice or contract.
How do I check whether a company is registered in Turkey?▾
Search the name or registration number above. If the business is on the official Turkey register, the record appears with its registered name and identifier. If nothing is returned, the name as spelled is not on the register — try a partial name or the number printed on the invoice or contract before concluding the business is unregistered.
How can I tell if a Turkey company is still active?▾
Each record carries the status the official Turkey register publishes for that entity. Registration status is a factual register field, not a judgement about the business — for ongoing certainty you can watch a record and be emailed when its registered details change.
