When you move out of a house, you must close your subscriptions to that house. Otherwise, you will be held responsible for the negative consequences that will emerge. There are two ways to cancel a subscription. One of them is to physically go to the company's branch and apply for subscription cancellation. The other is to cancel the subscription via the companies' website or e-government. If you are going to move to a house served by the same company, you can move your subscription to your new address instead of canceling the subscription. For this process, an application for a change of address must be submitted. In this process, an identity card, a counter number, and a bank account number are required.
