Global Registration Identifier for Donors
The World Marrow Donor Association (WMDA) is requiring an updated global standard for donor identification; WMDA collaborated with ICCBBA to develop and implement a Global Registration Identifier for Donors (GRID).

What is GRID?
The GRID standard is a 19-character identifier composed of three elements:
4-digit Issuing Organization Number (ION) – The National
Marrow Donor Program® (NMDP) / Be The Match® ION is 3553
13-character Registration Donor Identifier (RDI) assigned by the issuing
- A 2-digit checksum – a calculated number that ensures the preceding 17 digits are accurate and not mistyped
*other registries may have capitalized alpha characters in their GRID
Currently, donor IDs are issued in multiple, non-standard formats throughout the world. Some identifiers contain numeric character, some contain alpha characters and some contain punctuation symbols.
There is no control on the assigned IDs, therefore the possibility of duplicate donor IDs exists. If two donors are inadvertently assigned the same ID, the result could be infusing the wrong donor product into the waiting recipient.
GRID will have long term benefits by standardizing the donor ID format and ensuring donor IDs are unique around the world. This change is an important quality control measure to prevent errors and improve global communication and processes.
Assignment of GRIDs
NMDP / Be The Match has assigned a GRID to all donors on the Be The Match Registry. All new registry members are also being assigned a GRID. At this time, there is no change to how you do your work or identify donors in communications or on forms.
REMOVE: Over the next year, additional work will be done to share the assigned GRIDs with other systems. By April 2019 we will begin using GRID as the primary donor identifier while maintaining the DID for traceability.
We will follow and promote the GRID Standard as published by ICCBBA and additional implementation details as provided by WMDA. See this ICCBBA webpage for details.
Preparing your center for GRID
All NMDP / Be The Match partners need to be ready for GRID. If you use only NMDP systems and forms, you will be GRID-ready.
If you use systems, processes, and forms that integrate with the NMDP, you will need to conduct an assessment of your center. In an attempt to make this as easy and comprehensive as possible for you, we have created a GRID Readiness Checklist. This checklist is not intended to be all-inclusive and can serve as a guide to ensure you have considered as many impacts as possible.
In addition to the Checklist, there is a GRID Traceability Guide to help you see where you may find both GRID and DID in your primary systems or on the primary documents you use (final placement may change prior to implementation).
Please check our GRID FAQ document above. You can use Ctrl+F to search for a keyword in the document.
