Sending application forms to CGFNS

Dear all,

I am applying the CVS and I will send the application form and authorization forms to CGFNS by this week.

I realized the address of CGFNS on the online application form is:
P.O.Box 8628, Philadelphia, PA 19101-2651 USA

I am confused..... Should I send my application form to this address??

Or just to send them all to the address provided in the CGFNS website:
PO Box 8628, Philadelphia, PA 19101-8628 USA ?

Please kindly answer my question.
