For retrieving or getting a dependent IP pin reissued, it seems the most correct option is to go here: https://www.irs.gov/iden[product key removed]-scams/retrieve-your-ip-pin
and call the number listed.
"If you're unable to retrieve your IP PIN online, you may call us at [phone number removed] "
I am assuming there is not a way to retrieve a dependent's IP pin online (after much frustration)
