Updates to Access and Authentication Procedures for the Turkish Trade Registry System (MERSİS)
As part of recent updates to the Central Registry System (MERSİS), board members, branch managers, and individuals with limited authorized signatory will now be required to access to the system via the e-government (in Turkish, “e-devlet”) portal using either e-signature or mobile signature methods.
Until now, access to the MERSİS system could be facilitated through a MERSİS account created with the company’s official email address. However, starting from 14 April 2025, in order to enhance verification and transaction security, the option for logging into MERSİS via a user-specific account linked to the company email will be discontinued for Turkish citizens and foreigners with residence permits in Türkiye. From this date forward, these users will only be able to access to the system through the e-government portal using either e-signature or mobile signature methods.
Entries made through the e-government portal contain sensitive personal information, and therefore, it is essential that this data is not shared with third parties. Additionally, it is not desirable to take up company officials’ time for every trade registry application. Therefore, in order for MERSİS transactions for the company or branch you represent to be carried out on behalf of the company’s official representatives, it is necessary for each company or branch to individually log in to the system through the “e-government login” section available at https://mersis.gtb.gov.tr/Por
At present, trade registry certificate applications can only be made by the company’s official representatives. However, in response to potential issues encountered in practice, the Trade Ministry allows individuals who are not company or branch representatives to submit document applications.
