Your Rights and Next Steps
If you received a notification letter from Merkle, it means your personal information was involved in this breach. Here’s what you can do next:
- Take advantage of the complimentary 12-month Experian IdentityWorks membership being offered. This includes credit monitoring, identity restoration support, and up to $1 million in identity theft insurance.
- Monitor credit reports and account statements for any unauthorized activity. You are entitled to a free credit report from each of the three major credit bureaus once every 12 months.
- Consider placing a fraud alert or security freeze on credit files to help prevent new accounts from being opened in your name. This is free and can be done by contacting Equifax, Experian, and TransUnion.
- If you notice suspicious activity or believe you are a victim of identity theft, contact the Federal Trade Commission and your state Attorney General’s office. Filing a police report can also help if you need to dispute fraudulent charges.
