What is an MDC Code?
Do I need it?

The MDC is the Member Discount Code. Macha provides this to you to so you can obtain discounted member pricing on Nacha products and services. To get your recent MDC code, please contact info@macha.org. Once enter the code, the information will be saved in your user profile at www.nacha.org. This code will expire at the end of each calendar year.

In most cases you already have a profile created on the Nacha.org website and you should already see member pricing reflected on events, publications and subscription purchases. However if you are creating a new profile, please use the MDC code provided by Macha to immediately update your profile to receive member benefits on the Nacha website.
