How do I get pre-approved for the Ally Unlimited Cash Back card?
You can only get pre-approved for an Ally Unlimited Cash Back Mastercard® if you receive an offer to apply. Ally Bank does not allow you to check online for pre-approval. Furthermore, receiving an offer is also the only way to apply for this card at the moment.
If you're looking for a credit card that you can apply for right now, and get pre-approved, consider the Petal® 2 Visa® Credit Card, instead. This card offers 1 - 1.5% cash back on purchases and has a $0 annual fee. The issuer also allows you to check online for pre-approval before submitting an application. There are plenty of other pre-approved credit cards that you can consider, too.
Alternatively, you can try using WalletHub's CardAdvisor tool, to help find the right credit card for you. Just answer a few general questions, and based on your responses, CardAdvisor will provide you with some recommended credit card offers.
