Card.com is typically designed for individuals who are at least eighteen years old, as the agreement for opening and using a card involves legal responsibilities that most minors are not able to undertake. However, some services offered may provide options for individuals under eighteen with the consent of a parent or guardian. These setups might allow for a family member to manage the account while providing access for younger users. Each situation may be different, so it is important for individuals or guardians to review the specific terms and conditions associated with the card. Detailed information regarding age restrictions and necessary permissions can often be found on the official Card.com website.
