Merrick Bank Double Your Line® Mastercard® Review

Building or rebuilding credit is a process where having concrete goals can make all the difference. So the chance at doubling your credit limit with the Merrick Bank Double Your Line® Mastercard® is one of the better enticements for responsible financial habits on the market today.

Double Your Credit Line in Seven Months

The main selling point of the Merrick Bank Platinum Card is the chance to double the credit line in as little as seven months after opening an account. During the first seven months from account opening, all cardholders need to use their card and make at least the minimum payment on time every month. After that, cardholders receive a double credit line increase – automatically.

Thanks to the Double Your Line®, new account holders can watch their credit line jump to up to $2,700 in less than a year – significantly helping to lower their credit utilization ratio (with financially responsible card use). And, because Merrick reports to all three major credit reporting agencies every month, on-time payments can help their credit score improve significantly over time.

Merrick Bank also conducts account reviews regularly after the first year, with cardholders receiving a credit limit increase if they qualify. These features create an unsecured credit card product that grows with you on your credit journey – instead of holding you back.

Quick Online Pre-Approval

As with other Merrick Bank products, the Double Your Line® Mastercard® provides a quick online pre-approval process. Potential applicants can see if they are pre-approved within minutes without affecting their credit score. No credit check for pre-approval is a great way to see if the Merrick Bank Double Your Line® Mastercard® is right for you – without a hard inquiry on your credit report.
