Please clarify whether we use the unit codes listed on Sheet 1 or if we are supposed to request different codes from you to use?

You will need to apply for a center and unit code on www.nutritionday.org, order codes.  These codes are different than the codes listed on Sheet 1.

After applying online for my facility codes, when do they become active?

You must respond to a confirmation email from nutritionDay.org, which is sent to your email promptly after applying for these codes
