Sportsbook.com Withdrawl Question

[Derby Champ '94]

Hope this is the right forum to post this but had a question for anyone that uses them.

I have had an account there for years with no withdrawl issues - yesterday I go in there to withdrawl the small amount left in the account and they are requesting a copy of my driver's license and utility bill before they will process the withdrawl request.

Has anyone submitted this information to them and why would they need it?

Any reply will be much appreciated - I plan on using a CM sponsor next football season, sportsbook is crap.

Thanks.
