Bank of America provides several methods that you can use to request a credit limit increase. Before you submit a request, be certain that your credit card account is at least six months old, you have no late payments in the last year, and you can provide verified income information to prove that you can handle the added credit. If you pass those three tests, you can log into online banking under your credit card account, then select the “request a credit line increase” link under Card Details in your Account Summary. If you would rather not request a credit limit increase online — or if the online portal will not let you make the request — you can call the phone number on the back of your credit card. While this may seem like more work, you may have a better chance of getting your credit limit increased if you speak to a human instead of going the automated route. If you are in no hurry, you can wait until Bank of America conducts its automatic account monitoring to determine whether you qualify. There isn’t a set time frame in which this happens, but Bank of America states that it periodically checks accounts a few times each year.
