The guy that gives free cellphones at a kiosk asked for the last four numbers of my social security number. Do you think it's safe?

I can't get a new phone without giving the last four digits of my social security number to get a free cellphone. I'm already showing my driver's license and proof of income. 🤨Why do they need SS numbers too? These kiosks are set up outside in store parking lots. My phone is broken and I don't have the money to buy a cellphone 🤷🏼‍♀️.
