Registration on UNGM is free of charge. The United Nations Global Marketplace (UNGM) does not charge a fee at any stage of the registration process.
The access to procurement opportunities published by UN organizations on UNGM is also free of charge.
However, UNGM provides a value-added email service, UNGM Pro. This service involves a subscription fee and therefore should not be mistaken for the registration process, which is free of charge. For more information, read this article about what is UNGM Pro.
