...can we utilize the documents contained on the website as the method of Identification?
Technically, if that's what your CIP says, yes, you can use a certified copy of the articles or one printed directly from the web site.
Keep in mind that when you are performing CIP you are verifying that entity exists
(present tense). Publicly filed articles of incorporation stay on record for many years. If the corporation has been dissolved or is no longer in "good standing" they may still be there. While the distinction might not occur to the average examiner, it may be important to your bank on issues other than compliance.
A "certificate of existence" or "certificate of good standing," whatever your state calls it, proves the corporation was still alive and kicking at the time you opened the account. For this purpose, it's a better choice.
Depending on the capabilities of your state's SOS web site, it may be that finding the page where it says the corporation is in good standing and printing a copy for the file (with the browser printing the date across the bottom) serves you just as well.
