You can apply for the Buckle Credit Card either online or at any Buckle store location. Keep in mind that in-store applications require you to present a valid government-issued photo ID. Unfortunately, phone applications are not possible for the Buckle Credit Card.
You will need a credit score of at least 640 (fair credit) to be considered eligible. Plus, the issuer will also consider other factors when looking at your application, such as your income or existing debts.
