Finding Your Membership Number
Your National Air and Space Society Member ID # is required for membership verification. This number is located on your membership card or may be obtained by calling the Membership office at 202-633-2603, or by emailing MembershipNASM@si.edu.
Previous Membership Cards
Older Society membership cards use a slightly different format. Your membership number may be printed in a different location on the card or contain leading "0" - please review your card and if you are unable to locate the number contact the Membership office at MembershipNASM@si.edu.
