Nintendo Accounts do not charge you for creating or using an account. The account is free to create and allows access to various online services and features offered by Nintendo. However, some services or features within a Nintendo Account may require a subscription or additional payment. For example, Nintendo Switch Online is a paid subscription service that offers access to online multiplayer gaming, a library of classic games, and cloud saves. Additionally, some games or in-game items may require additional payment for access or purchase. It is important to note that Nintendo Accounts are separate from the Nintendo eShop, where digital games and content can be purchased. While the account itself is free, purchases made within the eShop will be charged to the linked payment method.
