To upgrade from Capital One Quicksilver to Venture, you can either accept an offer Capital One has already given you or call 1 (800) 227-4825 to ask them if you are eligible. The first step is to log in to your online account to see if Capital One has already decided you’re eligible for an upgrade. If you are eligible, there may be an “Upgrade Now” banner. Click on it, then check the box stating you’ve read and agreed to the terms, and then click “Upgrade Card.” You may also receive an upgrade offer either by e-mail or mail.
In all these cases, since Capital One made an offer to you, there’s no credit pull necessary. Your upgrade will go through and you will receive your new Venture card in 7 to 10 business days. You can continue using your old card until the new one arrives. And your card number, APR and credit limit should stay the same (unless the offer stated otherwise, so read carefully).
If you're a current Quicksilver cardholder and haven’t received an offer to upgrade to the Venture card, you can call customer service to inquire. There’s no credit inquiry just for asking if you’re eligible to upgrade to Venture. But if Capital One decides you are eligible and you request an upgrade, there will be a hard inquiry on your credit report. It will likely lower your credit score temporarily.
