The GMDN Codes are protected so that most members can only see Codes relevant to their product range. This is done by the member searching the GMDN Database until they find the most appropriate GMDN Term for their product. Members can see all 24,000+ GMDN Terms in the database. The member can then use a GMDN Code Credit to reveal the related GMDN Code (this is a 5-digit number). We provide all basic member accounts with 25 GMDN Code Credits when you join. Other membership types have more GMDN Code Credits, you can view our membership types at this link.
