forms 1096/1099-R hard copy filing address

Wondering what others think...the general instructions for the 1099-R forms indicate a mailing address for us in NYS as:

"Department of the Treasury, Internal Revenue Service Center, Austin, TX 73301"  (same as last year)

However I see on the actual 1096 "red" copy a filing address as follows:

"Internal Revenue Service, Austin Submission Processing Center, P.O. Box 149213, Austin TX 78741"

I'm assuming that the forms will get there either way, but would like to advise my clients accordingly for proper filing.

Thoughts?
