Midvale Indemnity Company, an auto insurance carrier based in Madison, Wisconsin, has begun mailing notices to consumers after finding that an outside party took advantage of a technical issue in its online quote system. Because driver’s license numbers are tied to a person for life and are useful for fraud, a notice like this deserves a careful read.
Midvale Indemnity Company’s Data Breach Investigation
Midvale’s notice states that the company recently became aware of a technical issue at the conclusion of its online auto insurance quoting process. It says it opened an investigation with outside experts and took steps to assess and respond. According to the company, the technical issue has been resolved, and it adds that none of its internal systems or databases, including those that store consumer information, were accessed. It also states that no policy information belonging to current or former customers was affected.
The central finding came on or about August 31, 2026, when Midvale determined that personal information of some consumers may have been affected. The investigation concluded that between June 30, 2026 and August 20, 2026, an unauthorized third party used personal information obtained from other sources to generate auto insurance quotes. During that quoting process, the third party may have acquired the driver’s license number of the person whose details were entered. In plain terms, the company describes a situation where the quote tool itself returned sensitive data to someone who should not have received it, rather than a break-in to its stored customer files.
The notice letter is dated September 30, 2026, and was sent under the American Family Insurance name in care of Cyberscout, a TransUnion company that Midvale retained to handle fraud assistance. A listing posted by the South Carolina Department of Consumer Affairs shows 2,305 people affected. The notice also states that 194 individuals in Rhode Island were involved, and it includes state-specific information for residents of Connecticut, the District of Columbia, Maryland, New York, North Carolina, Rhode Island and West Virginia. Multi-state notices of this kind commonly report different figures to different regulators, so the totals published by each agency may not match. The company has not, as far as the public filings show, announced a single nationwide count.
Anyone who received this letter did not necessarily ever apply for coverage. The notice says the unauthorized party used information gathered from other sources to run quotes, which means the people whose driver’s license numbers may have been returned could include individuals who never became customers and may never have heard of the company. That is one reason these letters can come as a surprise, and why recipients are encouraged not to dismiss them as junk mail.
This is not the first time Midvale has disclosed trouble with its online auto quoting platform. A notice the company filed with the California Attorney General in 2021 also described a data security incident involving an online auto insurance quoting platform operated by Midvale. That earlier matter is a separate incident with its own dates, and nothing in the current notice should be read as combining the two. It does, however, add context for consumers wondering how an insurer’s quote tool can become a path to personal data.
Why driver’s license numbers matter: criminals use them to build convincing profiles, to open or take over accounts, to submit fraudulent claims for government benefits, and to craft targeted phishing messages that quote real details back to a victim. A license number is not changed as easily as a password or a credit card number, so the risk can last for years. When one stolen identifier is combined with a name and address from an unrelated leak, a fraudster often has enough to attempt more serious fraud.
Insurers are an attractive target for this style of abuse because quote engines are designed to be fast and to pre-fill information so shoppers do not have to type it. That convenience can be exploited by automated tools that submit large numbers of quote requests using details taken from other breaches. Regulators have paid close attention to this pattern across the auto insurance industry in recent years, and companies are expected to test, monitor and limit what their quoting tools return.
What happens next is uncertain. Midvale has not publicly said how many total consumers were sent letters, how the unauthorized party was able to pull the data, or whether it has identified who was responsible. The company says it strengthened security controls related to its quoting platforms and has not identified further suspicious activity. Individuals who got a notice may wish to preserve it, record the date it arrived, and keep copies of any correspondence, since those details can matter if legal claims are later pursued.

A data breach attorney can review the facts, explain the options available to you, and help you understand how the exposure of a driver’s license number could affect you in the months and years ahead.
When Did This Breach Occur?
According to Midvale’s notice, the unauthorized quoting activity took place between June 30, 2026 and August 20, 2026. The company states that on or about August 31, 2026, its investigation determined that some consumers’ personal information may have been affected. Notice letters are dated September 30, 2026.
These are three separate dates: when the activity occurred, when the company confirmed the impact, and when letters went out. The roughly seven weeks of activity, followed by a delay before individuals were told, is worth keeping in mind if you are deciding how closely to review your accounts for misuse over that period and afterward.
What Information Was Breached?
The notice says the information that may have been affected is the recipient’s driver’s license number. Midvale does not report that Social Security numbers, financial account numbers or policy details were involved.
Even a single identifier can be misused. A driver’s license number may be paired with a name, address or date of birth gathered elsewhere to support identity theft, fraudulent benefit claims or phishing aimed at the person it belongs to.
What You Can Do
Midvale is offering single bureau credit monitoring, a credit report and a credit score at no charge, with alerts for twelve months from enrollment, plus fraud assistance through Cyberscout. Enrollment requires the unique code in your letter and must be completed within 90 days of the letter date. A help line is staffed Monday through Friday, 8:00 a.m. to 8:00 p.m. Eastern, at 1-833-516-8757.
Beyond that, review your credit reports for free at annualcreditreport.com, consider placing a fraud alert or security freeze with Equifax, Experian and TransUnion, and watch for unexpected mail from state agencies, particularly about unemployment or other benefit claims you did not make. Be cautious with any call, text or email that mentions your license number or an insurance quote you did not request. You can also contact your state’s motor vehicle agency to ask what options exist if you suspect your license number has been misused.
