Update announcement for MERSİS e-signature application
MERSİS wants to switch to the new version of the application used in electronic signature transactions.
In the MERSİS announcement, it is stated that the ArkSigner application used in e-signature transactions has been updated and the new version should be installed as of May 4, 2026.
It would be useful for authorities planning a company establishment, change or approval to check the electronic signature environment before the transaction day. The update link should be used directly from the official announcement page of MERSİS; Unverified installation files sent via e-mail or message should not be trusted.
This announcement does not mean that the company's authorized signatories or its form of representation have changed. The technical application version and the authority to act on behalf of the company are different issues. If authority sharing is required, the system's authorization options should be used instead of sharing a personal password.
