One proactive step you can take is to consider placing a fraud alert on your credit reports. This alert makes it harder for someone to open new accounts using your identity, as creditors will need to take extra steps to verify who you are. You can set up a fraud alert by contacting any one of the three major credit bureaus.
Regularly review your financial account statements and any bills for services you receive. Look for any charges or activities you do not recognize. If you spot anything suspicious, report it to your bank or service provider right away. It's a good idea to keep this practice up for several months.
