Best Answer: IRS doesn't mail checks at all. The Treasury Department Bureau of Accounts does it. Your refund was MAILED on Feb 16th, 2010, so it is up to the Post office to have your mail delivered to you. It is out of IRS hands now. So if you don't receive your refund check by March 126, 2010 then contact IRS.
