When your credit score isn't very healthy, it can result in roadblocks when you try to open a credit card account, rent an apartment or purchase a car. Fortunately, you can legally use a method called "piggybacking" to quickly improve your credit score. Piggybacking involves becoming an authorized user on someone else's well-maintained account and benefiting personally from that person's good credit history. The best part is that you don't have to have access to the account or even use it. All credit history comes from the account holder, but your credit score reaps the rewards.

Step 1

Ask someone you know and trust, who has good credit, if she will add you as an authorized user on one of her credit card accounts so that you can improve your credit score. It's important to make the distinction that you don't want to have use of the account.

Step 2

Ask the person to call the credit card company and ask if it will export the account's information to your credit reports once you are an authorized user on the account. If the credit card company won't export the account's information to your credit report, becoming an authorized user on the account won't help your credit score.

Step 3

Give the account holder any personal information, such as your full name, that's required to add you to the account. Some creditors will allow account holders to simply log in to their credit card account online and add a few pieces of information to add an authorized user.
