Repair Credit Score

Don't contact the collection agency

If you have an old account that's already in collection, there is another reason to leave it alone. If you make contact with the collection agency, you let that agency know that you are alive. Collectors will start calling, day and night, until the account is paid. Don't reach out and invite all that stress and harassment into your life unless you have the money and are prepared to pay off the account.

Don't Close Old Accounts

Since the age of your credit history is a factor in your Credit Score or FICO Score, it's a good idea to keep old credit accounts open. That old department store card that you haven't used in years can seriously improve your credit rating; as far as the Credit Scoring algorithm is concerned, that's an account that's been
in good standing for a long time.

The other important point is that closing an account won't make it go away; it'll still appear on your Credit Report as a closed account. It's better to have an open account with the potential to boost your score.

Don't Open New Accounts

It's a bad idea to run around and open new accounts just to boost your credit. You could end up with a lower Credit Score since length of credit history is important, and too much new credit is detrimental. Concentrate first on keeping your existing accounts current.
