60+ IBM i User Groups and Communities to Join


The strong community and culture that have grown up around the IBM i platform in the 30 years since it launched as the AS/400 underscores the success and popularity of this well-known technology. There are dozens of related user groups out there that help people get out of their everyday mindsets with the chance to interact with others who know IBM i—and who may be using it to address similar challenges in a new way. Case in point: Did you know there are more than 26,000 members of LinkedIn’s group for IBM i, iSeries, and AS/400 professionals?

Many users have spent much of their careers working with IBM i. In fact, our recent poll showed that 56 percent of respondents have 30+ years’ experience with the platform, meaning many of you may be looking forward to retiring soon, or will have to decide what to do when your IBM i talent retires! These user groups are critical as a place where newer IBM i professionals can look for information and best practices as they ramp up on the many ways IBM i is an amazing and powerful system. As newcomers come on board, make sure you share your knowledge and set them up for success.

To help you navigate this vast playing field, we’ve compiled a comprehensive list of IBM i user groups around the world.
