Most credit card companies periodically review a customer's account and give limit increases when the cardholder's income, credit history and account history warrant additional credit. However, customers can also request limit increases between reviews. You can ask for an increase over the phone, in person at the issuing bank or by letter.
Put your name, address, account number and the date in the upper-left corner of the page. Include a subject heading, such as "Re: Credit Limit Increase."
Request for Increase
State in the first paragraph that you want to increase your credit limit, and tell the company how much additional credit you want. Although credit card companies do not make limit increase decisions based solely on what you are going to do with more credit, providing a good reason, such as making a big purchase, funding repairs or paying for large events or vacations, could help sway the decision in your favor.
Ability to Repay
Inform the card company why you can afford the increase. Provide details on situations, such as a new job, a raise in pay or household expense decreases, that allow you to make higher payments.
Remind the company how long you have been a customer and of the consistency of your previous payments. If you have recent late or partial payments, the card company will likely decline your request for a limit increase.
End the letter with your phone number and email address, and indicate to the company your preferred method of communication. Thank the company for considering your request, and sign and date the letter. Send it certified mail with a return receipt so you know it was received.
