ID is asked for when registering for eBay's Managed Payments, when you wish to sell on eBay, but you need to be sure it came from eBay.
Did it come through eBay messages and address you by your real name and not just your username? Then, it's from eBay.
However, to be sure contact them, their lines have just opened and there's a good chance now, of getting Dublin to answer. Have them confirm the message came from eBay.
This is the easiest and quicket way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
