If a Interstate 35 CSD letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Interstate 35 CSD has officially reported a data breach incident in Iowa, as indicated by a public filing made on January 20, 2026. The company is currently investigating the scope of the event, which may involve personal information.
What to do after the letter
Confirm the notice is genuine
A legitimate Interstate 35 CSD notice references the specific incident reported to the IA Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
