It's a real number/company as stated above. They called me back regarding my Federal Government health insurance when I had a question.

SHPS is a legit company.  Various companies outsource through them to manage Healthcare.  when they call they do ask you to verify your address, age, DOB, etc.   In the case of my company if they ask you to enroll in a Healtcare class and you do not you will pay more in Insurance benefits.  

Being on a DO NOT CALL list does not matter since they are representing your Employer.  If you won't talk to them you may wind up paying higher insurance premiums.

Said they sent us information in the mail and wanted to check out account details? This sounds more than fishy

Call came and asked for my wife.  I told the guy she wasn't available, and he pressed and asked again for her.  When I again told him i was her husband and asked how I can help, he just hung up the phone...hasn't called back since

This number comes up at least once a day...today, 4 times. We called the number back, today, and the woman who answered (who, by the way, was porky) said she couldn't help us as she was from the "security office." She said to call back Monday. We googled the phone number and SHPS came up which is a "health insurance company." I found the corporate office number in Kentucky and, guess what?...nobody answered, nor were there voicemail capabilities or options available. Yes, fishy. This outfit also doesn't seem to have any local agents where we live. I wonder if their attorney general and their state insurance department know how they're operating?

Says they are calling for Medco about a presciption plan through your insurance. Very rude! When I told them I was on the no call list they hung up

SHPS is a third party health care administrator. They manage Cobra, FSA & HSA accounts as well as the benefits for many employers throughout the United States. The reasons you may be getting their calls are the following:

1. Health care benefits (info may be wrong, or it's a follow up on an open call)
2. Cobra non-payment
3. HSA Account (same as #1)
4. FSA Account (same as #1)
5. Insufficient documents (for health insurance)
