I'm still busy checking every prefix on proven existence. But it's rather depressing to learn how many companies did not survive the worldwide crises, have been aquired, or just ceased intermodal operations. Started in November 2010 with 3750 prefixes on the new Prefixlist.com, soon the total amount of prefixes will drop below the 3000. So why were so many non-existing prefixes on The World's Largest Containersite in the first place? Main cause is the way Prefixlist.com and all the other likewise sites start. Prefixlist.com started in 2001. In order to collect as many prefixes as possible you just copy all you can find on the internet. In all the years after that you just add and add, but never delete anything.Recently I found sites that are exact copies of Prefixlist.com, but unchanged versions of months ago. And by just copying you copy the mistakes too. Earlier this year I mostly filtered out these mistakes and now all prefixes are deleted from owners that left the containerstage the past 5 years (2007-now). But despite all research and caution it's inevitable that some prefixes are wrongly deleted. So if you suddenly miss a prefix of which you're sure it still is out there, please notify me.

It's very hard to keep up in the ever changing containerworld.  You surely find more prefixes on other sites, but Prefixlist.com will be and remain the most accurate and reliable.
