Yes, FTC.gov provided the phone #s of the thre agencies (Experian, Equifax, and another whose name escapes me).
The 3rd is Transunion.
Call all three credit reporting agencies and “Freeze” your credit. You can do this online.
It’s either free or a nominal charge. I recall two were free and the third just a couple dollars.
Freeze your credit!
Some agencies let your choose your PIN.
Some auto-gen a PIN for you.
Experian, Equifax, Transunion are the three.
