To find your membership ID number, please visit this link: member.usafencing.org/search/members. Please note that the default setting for the member search is for active members, so if you're a lapsed member looking for your member ID to renew, change the option under "Active Only?" to be "All Members" instead of "Active Members".
Please be aware that you can only search for members if you are logged into your USA Fencing account.
