Probably best not to post active tracking numbers on a public forum, but i ran it through Trackitonline.ru and the results came back saying the format is used by multiple carriers:
TNT was the only one I've actually heard of, all the others appear to be located overseas (majority Chinese, if not all). I didn't try running the number through any of the suggested carriers, though - I get mail through TNT frequently and have never had KED in the number, so it would seem more likely to be one of the others.
