| Comment | Unique identifier of the donor/CBU: If you are an EMDIS member, you can use the same ID as you use for that system (EMDIS hub code + donor identification allocated by the associated donor registry). For non-EMDIS members we recommend to use two digit ISO country code of the associated donor registry + donor identification allocated by the associated donor registry. For example: AU600196166, DEGOE-35487, US087013165, SB45. However, you are also allowed to use just the donor ID allocated by your registry. |
