This happened to me a few months back. I got the letter one day, and then debit card the next. A few weeks later my employer sent around a notice to contact like four different government agencies. I just followed the IDES website's recommendation and filled out their online form. This is the reply below. My underlines. I checked my credit reports as well.
Thank you for email. You should know that in most instances of fraud, IDES’ integrity measures stop claims from being paid out before we hear from you.
Therefore, we kindly request for your patience in waiting for us to contact you during this time that we are experiencing a high call volume and increase in email reports of fraud. We will respond to your email in the order in which it was received. It is not necessary to also contact us by phone.
In the meantime, you can act.
What steps should I take if I receive a debit card and did not file for unemployment insurance?
If you suspect a claim has been submitted using your information, and you have not applied for unemployment insurance benefits in Illinois, take the following steps:
DO NOT DELAY AND ACT QUICKLY
DO NOT activate the debit card that was mailed to you.
DO NOT contact KeyBank.
Destroy the card.
Request your free credit reports via http://www.annualcreditreport.com and review them for any fraudulent activities.
What happens after I report the identity theft to IDES?In most instances of fraud, we stop the unemployment claim and prevent payments from being made before hearing from you.
You will not be held responsible for the fraudulent claim if the investigation finds that you were a victim of identity theft. That is why prompt reporting and not activating the card are critical steps in this process.
