how many credit cards can you have
The average number of credit cards Americans own is three to four. According to Credit Karma, there is a correlation between having a high credit score (800+) and having more credit cards (7), compared to people with lower scores.he number of credit cards you have does make a difference for one of the biggest factors: Your total debt owed, as a percentage of your credit limit. Since every new credit card increases your total credit limit, adding another card decreases your debt-to-credit ratio (as long as you don't add more debt).
