Checking my last day of health coverage - what worked for you?

I am not sure what date my benefits stop after being let go as a logistics coordinator. This is my first time dealing with any of this. The letter is unclear about dental and vision. Did coverage match what HR said?

Ask HR to confirm the exact date in writing. I also called the insurance company to double-check.

Thanks for writing this out. I went through something close to it 3 months ago, and it got easier once I kept a simple log of every call and form.
