İYS (commercial message system)
In Turkish: İYS (İleti Yönetim Sistemi)
The Turkish system where you can see and manage which companies may send you commercial SMS, calls and emails.
In Türkiye, businesses generally need your permission before sending commercial messages, and İYS is where these permissions are recorded. You can look at your list and withdraw permission from companies you no longer want to hear from.
Beware: a message that claims to be from İYS and asks you to click a link or enter card details is not the real system. Open the service yourself instead of using a link in a message.
What to do
- Check which companies have permission to contact you and remove those you do not want.
- Never enter card details in a page you reached from a message.
- Use the sender's own opt-out option when a message offers one.
