Yes. BDOI® currently allows you to join more than one Blood Group Community. However, we strongly encourage you to join only your own blood group community to help keep the platform accurate and meaningful.
BDOI® does not currently restrict members from joining multiple Blood Group Communities.
However, since every individual has only one blood group, we recommend joining the community that matches your actual blood group. This helps:
If you wish to learn about other blood groups, you are welcome to explore or join those communities. However, for the benefit of the entire BDOI® community, we request that members actively participate primarily in their own Blood Group Community.
As BDOI® continues to evolve, Group membership rules may be refined to better support the platform's mission.
Every blood group is unique, and every donor matters. By participating in your own Blood Group Community, you help build a trusted network that can inspire more donors and support patients across India.
