The İleti Yönetim Sistemi (IYS), or Message Management System, is a crucial digital platform in Turkey designed to give you, the citizen, full control over the commercial electronic messages you receive. This national database, established under the oversight of the Ministry of Trade, acts as a central hub where all service providers register their current commercial electronic communication consents. It ensures that businesses adhere to regulations regarding promotional messages, calls, and emails, allowing you to decide who can contact you and through which channels. Beyond just storing permissions, the IYS empowers you to actively manage these consents. You can easily grant or withdraw approval for commercial communications from various service providers. The system not only simplifies the process for individuals but also provides a secure and transparent environment for businesses to comply with communication laws. Think of it as your personal control panel for digital marketing interactions, bringing order and choice to your inbox and phone.

Getting Ready to Control Your Commercial Messages

Accessing Your Message Preference Dashboard

  1. Navigate to the official IYS website at iys.org.tr.
  2. On the homepage, select your preferred login method. You have two primary options: e-Devlet ile Giriş (Login with e-Devlet) or İletişim Bilgileriyle Giriş (Login with Communication Information).
  3. For e-Devlet ile Giriş: Click this button, which will redirect you to the secure e-Devlet portal. Enter your T.C. Identity Number and e-Devlet password. Once successfully authenticated, you will be directed back to your IYS dashboard.
  4. For İletişim Bilgileriyle Giriş: Click this option. You will then enter a single phone number or email address that you wish to manage. A one-time password (OTP) will be sent to that contact method. Enter the OTP on the IYS site to gain access to your preferences for that specific contact detail.

Managing Your Communication Choices

Restoring Your Access to Message Management

⚠️ Cannot access my account (Login issues)

Cause: Incorrect e-Devlet credentials, incorrect contact information, or an expired one-time password.

Solution: If using e-Devlet ile Giriş, double-check your T.C. Identity Number and password. If you forgot your e-Devlet password, use the password recovery options on the e-Devlet portal. If using İletişim Bilgileriyle Giriş, ensure you entered the correct phone number or email. Request a new one-time password if the previous one expired or was not received. Always verify your internet connection.

⚠️ My contact details are not listed or incorrect in 'Profilim'

Cause: The contact information may not have been added to your IYS profile, or there might be a typo.

Solution: After logging in, navigate to the Profilim section. Use the option to add new phone numbers or email addresses to ensure all your relevant contact details are registered within your IYS account. Make sure to enter them accurately.

⚠️ A company is sending messages despite my 'RET' (reject) status

Cause: The service provider may not have processed your rejection yet, or there might be a delay in system updates.

Solution: First, verify that your rejection is correctly recorded in the İzinlerim section for that specific service provider and communication channel. If it is, and you continue to receive messages, use the Şikayetlerim feature within IYS to formally report the service provider.
