800-887-4015

Wanted to talk about my Fedility 401K. havent called them back.

Don't. They keep people on the phone to waste their time.

I didn't answer but got a call from a different number asking me to call this 800 number as well.  Said they were from Fidelity but it is not the same number as on the Fidelity website.  Not calling them back.

This number is actually from Fidelity, it's their workplace accounts line (which is why it's not on the main website). They handle, among other things, older accounts that you get through your company.
