Corporation Service Company, a global provider of business and compliance services, formally reported a data breach to Indiana state authorities on August 13, 2026. This notification confirms a security incident that initially occurred on August 10, 2025, affecting sensitive information processed by the company.

The breach exposed multiple categories of data. These include Full Name, Social Security Number, Date of Birth, Mailing Address, Banking and Direct Deposit Details, Tax Return Information, Corporate Officer and Director Records, and Driver License Number. These types of information are often considered foundational for personal and corporate identity.

Exposure of such a comprehensive range of personal and corporate data creates significant risks for affected individuals and entities. The compromised information could potentially be used for various forms of identity theft, financial fraud, or unauthorized access to accounts. Individuals should be aware of the heightened risk and remain vigilant.

If you received a data breach notification from Corporation Service Company, it is important to review the letter carefully for specific details pertaining to your situation. Consider placing a fraud alert or security freeze on your credit reports with the three major credit bureaus (Equifax, Experian, and TransUnion) to help prevent unauthorized accounts from being opened in your name.

Regularly monitor your financial account statements, credit card activity, and explanations of benefits for any suspicious transactions or unfamiliar charges. Additionally, be cautious of any unsolicited emails, texts, or calls requesting personal information, as these could be phishing attempts using the exposed data.

Details of this incident are based on official public filings made with regulatory bodies. While the investigation status is currently described as 'monitoring,' individuals should proceed with standard identity protection measures as a precaution.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Replace exposed ID documents

    Contact your state DMV or the issuing agency about replacing an exposed driver's license, passport, or government ID number.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
