Preparing Your Information for an IETT Submission

Navigating the IETT Online Application System

  1. Accessing IETT's online services to submit an inquiry or request for information doesn't always involve a traditional 'login' in the sense of a user account. Instead, IETT provides dedicated online application forms for various purposes. Begin by visiting the official IETT website at iett.istanbul.
  2. Navigate to the 'Online İşlemler' (Online Services) section, which usually can be found in the main menu or footer of the website. Here, you will find options such as Yolcu Başvuru Formu (Passenger Application Form) for complaints and feedback, or Bilgi Edinme Hakkı Başvuru (Right to Information Application) for formal information requests.
  3. Select the appropriate form based on your needs. Carefully fill in all required fields, providing accurate personal and incident-related information. Once submitted, the system will typically provide you with a reference or application number. Make sure to record this number, as it is essential for tracking the status of your submission through the digital portal.

Resolving Difficulties with IETT Online Processes

⚠️ Cannot access or submit an online form

Cause: Potential browser compatibility issues, internet connectivity problems, or incorrect data entry.

Solution: Ensure your internet connection is stable. Try using a different web browser (e.g., Chrome, Firefox, Edge) or clearing your browser's cache and cookies. Double-check that all mandatory fields are correctly filled out, paying attention to any specific format requirements for dates or ID numbers.

⚠️ Forgot application or inquiry number

Cause: Misplaced or forgotten the unique reference number provided upon submission.

Solution: We know being locked out or losing critical information is stressful. If the website offers a 'track application' feature that allows retrieval via personal details (like ID and email), use that. Otherwise, contact IETT customer support directly via phone (0212 372 22 22) or email, providing as much detail about your original submission as possible. They can often assist in retrieving your reference number.

⚠️ No response to an inquiry

Cause: Processing delays, incorrect contact information provided, or inquiry still under review.

Solution: First, use your application number to check the status online, if available. If there's no update or a significant amount of time has passed beyond the expected response period, reach out to IETT customer support at 0212 372 22 22. Be prepared to provide your application number and all relevant details of your original submission. They can escalate your concern and provide an update on the 'tahkikat' process.
