You can only get pre-approval for the Exxon Mobil credit card if you receive a special offer by mail.  You can’t get pre-approved on the website itself, so the best idea is to check the eligibility requirements.  To get approved, you’ll need to be aged 18 or over and have a steady source of income.  You should also have a credit score of 640 or more to increase your chances of getting the card.  Find out how to increase your credit score quickly.
