Track Code - where is it?

[s348248]

I created a track about 4 years ago. Now, I would like to REGISTER the track so RECORDS are shown on the website here: http://stats.kartracing-pro.com/records.php

But where on earth do I find the track code for the track I created, from scratch?? Can't find any info in the forums re "track code" for track registration.

Thanks for any help.

It is shown during export. If I miss a track code, I re export the track .trp file and then I copy and save it..
