Quick answer: The Turkish Trade Registry Gazette (Türkiye Ticaret Sicili Gazetesi) is the official publication archive for registered commercial events such as company formation, capital changes, address changes, manager/director appointments and other registry announcements. It is highly useful for company due diligence, but it should not be treated as the only source needed to prove a company’s current status or signing authority.
This guide covers Trade Registry Gazette search and corporate-history verification. For MERSİS system data, use MERSİS Company Registration in Turkey. For a current company-status document, use the dedicated Activity Certificate guide.
What the Turkish Trade Registry Gazette Actually Shows
| Gazette record |
What it can help verify |
What it does not prove by itself |
| Formation announcement |
Registered company title, initial capital, address, founders and formation details published at registration |
That every item remains unchanged today |
| Capital increase/decrease |
Published changes to registered capital |
Current financial strength, cash balance or solvency |
| Address change |
Published registered-headquarters change |
Physical operating presence or suitability of the premises |
| Manager/director or representation announcement |
Published appointment and representation changes |
That no later change exists unless the full history is checked |
| Share-transfer / ownership announcement where registrable/published |
Relevant published ownership changes |
A complete beneficial-ownership analysis in every structure |
| Liquidation / dissolution-related announcement |
Published corporate-status events |
Every debt, lawsuit or insolvency fact affecting the company |
Due-diligence rule: Read the Gazette chronologically. A formation announcement tells you how the company started; later announcements tell you what changed.
The Gazette is an official publication archive of commercial-registry announcements.
Official Portal: Where to Search
The official portal is ticaretsicil.gov.tr, operated for the Türkiye Ticaret Sicili Gazetesi. The portal provides:
- announcement viewing (İlan Görüntüleme);
- trade-name search (Unvan Sorgulama);
- certified-copy services;
- Trade Registry Directorate information;
- Gazette publication and fee information.
Current portal guidance states that users should sign in to search/view Gazette announcements for free. Account registration and e-Devlet login options are available through the portal.
The official site states that announcements published from 1957 to the present can be accessed, saved and printed through the service. Do not use the older claim that the online archive begins only in 2003.
How to Run a Trade Registry Gazette Search
- Start with the full legal company title. Copy the title from a reliable company document rather than relying on the brand name.
- Use the official Gazette portal. Sign in and open the announcement-search function.
- Narrow the result where possible. Registry number, registry office and company title help distinguish similarly named entities.
- Open the formation announcement first. Establish the original company identity, address, capital and management structure.
- Read later announcements chronologically. Look for capital, address, management, representation, ownership and status changes.
- Cross-check the latest status. For an important transaction, use the Gazette together with current registry/company documents rather than relying on one historical PDF.
Search the formation record, then follow later announcements to reconstruct the registered history.
Trade Name Search and Gazette Search Are Different
The portal also provides Unvan Sorgulama, which can show whether a trade name is in use and, where available, the registry office and registry number associated with it. That is useful for company-name research.
But a trade-name search is not the same as reading Gazette announcements. For a proposed new company name, use the dedicated Turkey Company Name Check and remember that trademark risk is a separate question.
How to Read the Most Common Gazette Announcements
| Turkish term |
Meaning |
What to review |
| Kuruluş |
Formation |
Company title, headquarters, founders/shareholders, capital, managers/directors, representation |
| Sermaye Artırımı / Azaltımı |
Capital increase / decrease |
New registered capital and effective corporate decision |
| Adres Değişikliği |
Address change |
New registered headquarters and effective date |
| Müdür / Yönetim Kurulu Değişikliği |
Manager / board change |
Who was appointed or removed and representation terms |
| Temsil / İlzam |
Representation / binding authority |
Sole vs joint signature and registered authority wording |
| Pay Devri / Ortaklık Değişikliği |
Share / ownership change where applicable |
Relevant ownership changes and their registration/publication treatment |
| Tasfiye |
Liquidation |
Liquidation status and appointed liquidator information |
Do not infer financial health from a capital increase or decrease alone. Registered capital is a corporate-law figure, not a live balance sheet.
Can the Gazette Prove Who Can Sign Today?
It can provide important evidence, but avoid the blanket statement that one Gazette page proves current authority “100%.” A historic appointment can later be amended or revoked.
For a material contract, compare:
- the latest relevant Gazette announcements;
- current Trade Registry / chamber records;
- the company’s current signature circular or signature/representation evidence where appropriate;
- the specific authority wording applicable to the transaction.
For the signing-authority document itself, use Signature Circular in Turkey.
Gazette vs Activity Certificate vs Signature Circular
| Document/source |
Best use |
| Trade Registry Gazette |
Published corporate history and registered-event announcements |
| Activity Certificate (Faaliyet Belgesi) |
Current chamber/registry-facing status evidence for many commercial uses |
| Signature Circular / representation evidence |
Current registered signing/representation information for company authorities |
| MERSİS |
Central registry data and registration/change workflow |
No single item should automatically be treated as a complete due-diligence file for every transaction.
When You Need a Certified Gazette Copy
The official Gazette portal provides certified-copy services. Current TOBB information states that e-signed or wet-signed certified copies of published announcements can be obtained through the portal.
A normal downloaded/printed announcement may be useful for research, while a bank, court, tender authority, overseas authority or counterparty can request a certified or otherwise formally authenticated version for its own process.
What the Gazette Does Not Contain
Do not expect a Gazette search to reveal everything about a company. It is not a substitute for:
- financial statements;
- live bank balances;
- tax-debt status;
- litigation research;
- sanctions screening;
- beneficial-owner/KYC analysis;
- sector licence verification;
- credit-risk analysis.
For high-value transactions, build the due-diligence scope around the actual risk rather than assuming the Gazette alone is sufficient.
Five Common Search Mistakes
- Searching only the brand name. Use the registered legal title.
- Reading only the formation announcement. Later announcements may supersede it.
- Assuming capital equals financial strength. It does not.
- Assuming one old signatory announcement proves current authority. Check subsequent changes and current evidence.
- Using unofficial databases when the official portal is available. Start from ticaretsicil.gov.tr.

Frequently Asked Questions
Use the official Türkiye Ticaret Sicili Gazetesi portal at ticaretsicil.gov.tr. Search with the company's full legal title and, where available, its Trade Registry office or registry number, then review the formation announcement and later announcements chronologically.
The current official portal states that announcements published from 1957 to the present can be accessed, saved and printed. The older claim that the online archive begins only in 2003 should not be used.
It can show published corporate events such as formation, registered capital changes, headquarters changes, manager or board appointments, representation changes, relevant ownership events and liquidation or dissolution announcements. A historical announcement does not prove that the same information remains current today.
Not safely by itself. A historic appointment or representation announcement can later be amended or revoked. For a material transaction, review the latest relevant Gazette history together with current registry or chamber records and current signature or representation evidence.
MERSİS is the central registry data and electronic workflow system used for registration and changes. The Gazette is the official publication archive for registered commercial events. They serve different functions and neither should automatically be treated as a complete due-diligence file on its own.
The official portal provides certified-copy services. A normal downloaded announcement may be enough for research, while a bank, court, tender authority, overseas authority or counterparty can require an e-signed, wet-signed or otherwise formally accepted certified copy for its own process.
