Update domain info (email received)

I got the following email:

Charles Kuttner — Customer Number: XXXXX



ICANN, the Internet Corporation for Assigned Names and Numbers, requires us to ask you to review and update your detailsfor the following domain(s):



I’m omitting some of the info, such as login info that was provided, but my customer number was correct. 

   I’m concerned this may be a phishing attempt rather than legitimate, particularly since if I log in directly to godaddy.com, I can find a place to update my details. Cisco (through my system) said this looked like phishing to them.

   Anyone know if this is for real, and if so, how to verify my domain info on godaddy.com site without that click-through?

   Thanks in advance....oh, one bonus: when I tried to post this, I got the following  message: “Your post has been changed because invalid HTML was found in the message body.” Sounding more and more like phishing...
