How long did your Verification Letter take to arrive?

Hey Guys I noticed that the Verification Message began showing up the IRS website early this week. So I called them yesterday and they said that a letter was emailed to me on February 23rd. But as she was telling me this she said that was the EARLIEST day that it could have been sent out and it could take up to 2 weeks. I'm just wondering how long did most people to receive their Verification Letter? Thanks in Advance
