About the NSS Mail Code

The NSS Mail Code is an 8-character code (e.g., "R04AM171") that identifies the type of mailing.  It is located near the top center of the renewal notice, in a box labeled "Mail Code".  The format is LDDLLDDD where L is a letter, and D is a numerical digit.

The Mail Code is an optional field, to allow for situations when you want to renew but do not have your Renewal Notice with you.  (Your membership card contains your Membership ID Number.)
