It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
By code if you mean product keys like windows then answer is no.
Ubuntu is completely free of charge. You don't need any product code. You can download it, burn a disc or create a live USB (using appropriate software) and install it. Even before installing you can select Try Ubuntu to run it directly from the live CD/DVD/USB.
There are no codes or keys required to install Ubuntu.
Installation is especially easy with the installer provided for Windows on www.ubuntu.com, known as the Wubi installer. While an installation from Wubi will prevent hibernation (suspend works just as well in my opinion) and has some very minor read/write hindrances, it allows you to easily install and uninstall Ubuntu without all of the complications and possible dangers of partitioning.
