In our GMP News from September 2013 you learned about a draft of a FDA Guidance for Industry entitled "Specification of the Unique Facility Identifier (UFI) System for Drug Establishment Registration". This document's goal was to clearly identify pharmaceutical sites. The draft comprised (manageable) five pages - including the cover page. And in terms of volume this didn't change. However, some of the alternatives still mentioned in the draft, are not stated any longer - as one can find out when contacting the authority in these cases. The method now wanted is a registration by a D-U-N-S- (Data Universal Numbering System) number. This number - which is a 9-digit code - is supplied by the company Dun & Bradstreet.
