When E-TUYS Access Falters: Quick Solutions

⚠️ Cannot access E-TUYS after authentication

Cause: Lack of prior user authorization. Even with e-Devlet login, unauthorized users cannot perform actions.

Solution: We know being locked out is stressful. The fastest fix is to ensure you have completed the E-TUYS Yetkilendirme (authorization) process. This involves sending specific documents via KEP to the Ministry. Until this is approved, you won't be able to use the system fully. Verify with your company or consultant that your authorization is complete.

⚠️ Authorization documents rejected

Cause: Incorrect format or missing information in the KEP submission.

Solution: Double-check that your Application Petition, notarized Letter of Undertaking, and Authorization Form are filled out correctly. Ensure they are sent via your company's KEP address as an "e-yazışma" type, not a standard email, to the correct Ministry KEP address ([email protected]). All required signatures must be present.

⚠️ Problems with electronic signature

Cause: Expired e-signature, driver issues, or incorrect usage.

Solution: Confirm your electronic signature is active and properly installed on your computer with the necessary drivers. Ensure you are using the e-signature of the *person* who was authorized for E-TUYS, as another person's e-signature will not work even if they are from the same company.
