Being a member of a trade organisation who themselves are members of the GMDN Agency; I was contacted by the GMDN Agency (via email) on the 10th November 2014. This was concerning the revision of a particular medical device reference. They were requesting advice, as we produce this particular product. Now obviously I do not know when they actually decided to conduct this revision process (from a timeline point of view). However, my final communication with them about this particular revision was on the 21st November 2014 (after various question raised and answers supplied). The old number was made obsolete and three new numbers were issued. From the GMDN website the new numbers were created on the 5th December 2014.
Don?t know if this helps.
