Making a stealth eBay account. problem... help?

So I'm making a new stealth account but I got this:
--------
Confirm your identity by phone

Our automated system will call you and read a 4-digit PIN. You'll be asked to enter your PIN on the next page.
-----------

So what should I do? I don't know what triggered this since I've never had to do it before... maybe the name I used was used before or something. Everything is stealth, including the phone.

What should I do? This is a complete stealth account... should I use my phone number then remove it since a real cell phone number isn't that bad or should I just forget this one and try again?

And if I have to try again, any suggestions on avoiding this message?

I always got this phone verification when selling items. Just sign up with a call forwarding provider (get a new number that forwards to your cell or home phone) or get a bunch of cell phones (the first one is cheapest, and most convenient)

BTW: this is like the easiest limit to unlock.

Maybe a prepaid Sim card with an old cell phone. There cheap on eBay.

Any cheap VoIP povider will work, some even say Google Voice works for them if you want to go the free route.

One more thing - It is best to use a phone number that is located within atleast 50 miles of your stealth address.
