Thanks @LoganTann ! I've implemented couple of your suggestions. Not sure about 15 characters Ids because the function check the checksum and this seems to be the part of 18 characters Ids only.
Organization IDs are mostly 15 characters, and is one of the most important IDs to validate? Is there any way to do that?
