Commonly translated as *Commercial Register number* (doesn't matter that there arent't too many ggls -- there is no equivalent in the US!) but I'd definitely add [German] (as written, in brackets); that's very important IMO. ;-)

I also thought "commerical register number" might be the right term. However, Google only offers 1620 hits (compared to 218,000 for Handelsregisternummer) and most of them are Austrian and German. Therefore, I concluded it's not the standard term used in the US.
