(CNN) -- The names, Social Security numbers, birth dates, addresses, and driver's license numbers for 143 million people may have been accessed during the Equifax data breach.
The credit card numbers of an additional 209,000 people were also accessed, according to CNN Money. Those people will be directly notified, but everyone else has to go to a website created by Equifax and submit their last name and last six digits of their Social Security number to see if they were affected.
If you're concerned about whether your information is in the hands of hackers, here are five things you can do right now:
1. Check your free credit reports
Under federal law, people are allowed to request a free copy of your credit report once a year from each of the three credit reporting agencies: Equifax, Experian, and TransUnion.
2. Put a fraud alert on your credit
If you place a fraud alert on your credit, you'll be contacted if someone attempts to apply for credit in your name. The alert lasts for 90 days and can be renewed.
3. Keep an eye on bank accounts and credit card statements
Go through all your bank, retirement, and brokerage accounts, as well as credit card statements to check for suspicious activity.
4. Sign up for a credit monitoring or identity theft protection service.
According to the FTC, most monitoring services will alert you when a company checks your credit history, a new loan or credit card is opened in your name, a creditor says a payment is late, or if public records show you've filed for bankruptcy.
5. If you're really worried, put a freeze on your credit.
Officials say this is an extreme step that may not be necessary if you're uncertain if your information was compromised. A freeze will block anyone from accessing your credit reports without your permission. The credit freeze is usually not free, fees vary from $5 to $10.
