This validator was left out of the process of making the error messages 
translatable. It's fixed for version 7 with
https://forge.typo3.org/issues/66973

To fix this in your installation I'd first try to create a version with 
the translation mechanism and use the XCLASS mechanism to override the 
original function.

I assume that you mean the number in the last parameter of addError()? 
That is meant to be unique and therefore we simply use the Unix 
timestamp at the time that the developer inserts this number in the 
code. Chances are small that two numbers are generated at the same time. 
If an Exception is thrown then this number is used to link to a wiki 
page where the community can leave further hints on how to solve/prevent 
that exception.
(It's also useful to find the location in the code that throws the error 
:-) )
