Many years ago, your dad (or another close person👪) bought you a number and registered it in their name. Now you'd like to transfer it to another operator and have your own account. Wondering what to do? Put on your helmet and get reading. Everything will become clear in a moment.
Phone Number Assignment: What is it?
Simply put, assignment is a change of phone number ownership. It means transferring the rights and obligations arising from the contract from one entity to another. The rules of assignment are determined by the contract or the operator's terms and conditions, and you can get specific information by contacting customer service.
Phone number assignment most often concerns changes in data:
- from an individual to another individual, e.g., when you want to change mobile operators;
- from an individual to a company/cooperative (or vice versa), e.g., when you part ways with your employer;
- after the subscriber's death, if you want to keep the number.
Assignment When Transferring a Phone Number
Most often, future Vikings think about assignment when they want to change operators. That's when they remember that the phone number isn't registered in their name. And the law requires that during a number transfer, the owner's data must be 100% consistent. In such a situation, the only solution is assignment. After updating the data, you can place an order with the new operator yourself.

However, you don't want to waste time going to physical stores and/or contacting your current operator. At the end of this article, you'll find information on how you can easily transfer and assign a number in Mobile Vikings.
How much does number assignment cost and how to do it?
Each mobile operator has information regarding the assignment procedure in its terms and conditions. You can find a template for the number assignment document on their website. In most cases, a visit to a physical store by the current and new owner is required.
Below you'll find instructions for assignment with several Polish operators.
