Get your free annual credit report from all three credit reporting agencies

A credit score takes all the information from your credit report and distills it into a simple three-digit number. If you really want to be vigilant, it pays to check your credit history your scores are based on.

Visit annualcreditreport.com to get a copy of your report from each of the three credit reporting agencies. You might want to wait to check the report's accuracy until after you notice an unexpected change in your credit score, or you may want to be pre-emptive. Just remember, you can only check each bureau's report once per year for free.

Here's a good primer on how to read your credit report.

Credit cards

More and more credit cards are offering free credit scores with cardholders' monthly statements. Here's a list of major credit card issuers and the specific score information they'll provide cardholders.

Banks and credit unions

Some banks and credit unions will offer customers a free credit score every month or every quarter. If you have a loan with a bank, it's even more likely they'll provide a free credit score with your account. Here's a short list of banks and credit unions that offer free credit scores to customers.

  • 1st United Credit Union: FICO Score 2 based on Experian data

Third-party apps and resources

There are several third-party resources you can use to check your credit score if you don't have an account at one of the aforementioned credit card issuers or banks. These are available to anyone -- you just have to provide your Social Security number. Checking your credit score through these resources will not impact your credit score, as it's just a soft pull, not a hard inquiry.

Here are some places to get a free credit score:

The following resources provide both a credit score and some form of credit monitoring for free.

Be aware that these services often aim to make money off of you either by selling additional services themselves or referring you as a customer to other products. The credit report from all of these resources shouldn't require you to enter credit card information.

Track all three credit reporting agencies

Use the list above to check at least one credit score from each of the three credit reporting agencies. A FICO score is best, as it's the scoring model used in 90% of lending decisions. But you may notice there are many different versions of the FICO scoring model. Most commonly, you'll receive a FICO Score 8, which is a generic credit score. Lenders might use a unique model to make lending decisions on different types of loans.

As long as you regularly keep an eye on your credit scores, you're well ahead of the average American when it comes to staying on top of your finances.
