Project management institute (PMI) requires the certified professionals , to renew their credentials every 3 years. You need to collect PDUs in different categories. This applies to all professional certifications, namely PMP, PMI-RMP, PMI-SP, PMI-ACP , PgMP and so on. I have tried to collate all the possible sources to get Free PDUs, if you know of some more sources, feel free to share here.

Its unlikely that you will need any more sources than the ones listed below.  Feel free to refer this page to your friends.
