Chase offers overdraft protection for its checking accounts. The policy allows eligible customers to link another eligible Chase deposit account or apply for a Chase credit account to cover overdrafts. When a transaction exceeds the available funds in the checking account, Chase may cover it with funds from the linked account or credit line, thus helping to avoid declined transactions or returned check fees. However, it is important to note that this overdraft protection is subject to approval and comes with associated fees and interest charges, which vary depending on the specific type of overdraft protection chosen by the customer. It is advisable to review the terms and conditions, as well as the associated costs, before opting for overdraft protection.
