My credit score is in the low to mid XXXX 's despite a perfect payment record.. My total debt is about 5 % of my net worth, most in XXXX securities. Why is n't my score perfect? Checking my credit reports they seem accurate - perfect payment history! No court judgements, no bankruptcy history, no unpaid debts, etc. But, it seems misleading. I pay my only credit card off in full every month, no carry over balance, but it shows a max charge vs the limit even though paid. I keep my limit low to minimize identity theft and credit theft limits. My second card is a debit card, also paid every month. I get no reply to my specific question why my score is so low so I ca n't provide the information to resolve it.
