In preparation for the 70th Anniversary of the Moo Duk Kwan®, all practitioners with Moo Duk Kwan® lineage are invited to join the Alumni roster by submitting for authentication your rank information and/or copies of rank certificates or other credentials that you have received.

Each practitioner who submits credentials for authentication will be acknowledged by the World Moo Duk Kwan and the U.S. Soo Bahk Do Moo Duk Kwan Federation during the course of the 70th Anniversay Celebrations of the MOO DUK KWAN®. (11-09-1945 to date)

Members and Alumni of the U.S. Soo Bahk Do Moo Duk Kwan Federation need not submit copies of certificates as your ranks are on record, we are seeking to identify expatriate Moo Duk Kwan practitioners who wish to be recognized during the 70th Anniversary celebration.

Also in celebration of the upcoming 70th Anniversary of the Moo Duk Kwan® each person requesting authentication for certificates or other credentials will receive a LIFETIME DISCOUNT CODE valid for 10% off subscriptions at

To confirm that rank credentials you have received are legitimate submit your rank information and/or a copy of your rank certificates or ID cards for authentication by the only legitimate source of Moo Duk Kwan® issued rank certifications.

Email your rank information or certificate images to or upload scans or photos of your certificates or other credentials that you are submitting for authentication to your account at Your uploads will be private and only visible to those you approve as friends of your account and authenticators.

After your submissions have been carefully reviewed and compared to official Moo Duk Kwan® records, then you will be notified.

Another way to confirm that your rank certificates or other credentials are legitimate is to verify that the instructor or studio that you received your certificates through are in fact certified Instructors and/or licensed Moo Duk Kwan® facilities.
