Benefits end date after a layoff - what worked for you?

I was told my coverage ends on my last day, but the letter says the end of the month. This is my first time dealing with any of this. I do not want to be surprised by a bill. How did you confirm your end date?

Keep a copy of any coverage confirmation in case of later disputes.

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