Not on Paypal, but for my Ebay log in, yes. It is an automated call, probably from California, giving you a 4 digit confirmation pin jumber. At least, thats what it does for the ebay log in. During the sign in process, you will need to enter that pin number. Be aware, this happened to me a couple of times. It may have something to do with where you logged in. I suspect in my case it was because I logged in from a different IP address on a different computer. As I said, it happened to me a couple of times, but hasnt happened for a month now.
