First of all, you can download and print a handy reference card for these codes from
here. As you're probably aware, the codes we're discussing are just the serial number and the short code found on the note.
I understand that it might be difficult for new EBTers to follow our discussion about serial numbers and printer codes.
Some examples wrote:20 Euro P-P
10 Euro V-G
5 Euro N-P
...
I know there are V01***/G005/€10 bills, but I am not sure about the N/P/€5 bills.

You don't need a 10€ printed in N for Y?
However, it all becomes obvious once you familiarize yourself with the serial number scheme. The serial numbers have one initial letter, L to Z, which indicates for which country the note had been produced. The shortcode (as found on the front side of the note) also has one initial letter, D to U, which indicates the printing facility which printed the note.
It's just so much quicker to write "I got a brand new P/G/20€ note" than it is to write "I got a brand new Dutch 20€ note printed at Johan Enschedé & Zn".
Usually we shorten these serial numbers and short codes to just the initial letter, but sometimes it's worth mentioning some of the following numbers as well. For example, most of the 50€ notes printed by H (De la Rue, UK) for Finland have H006 in the beginning of the shortcode, while most of 50€ notes printed by H for Portugal have H004 in the beginning.
When we use the very terse (firstcharacter)/(secondcharacter) syntax, the former denotes the serial number letter and the latter the short code letter.
Here are the clarifications for the examples I posted above:
20 Euro P-P = a note printed for Netherlands in Giesecke&Devrient Germany
10 Euro V-G = a note printed for Spain in Johan Enschedé & Zn, Netherlands
5 Euro N-P = a note printed for Austria in Giesecke&Devrient Germany

I know there are V01***/G005/€10 bills, but I am not sure about the N/P/€5 bills. = There are 10€ notes printed for Spain whose serial number start with V01 and the shortcode starts with G005, but he's not sure about 5€ bills printed for Austria in Giesecke&Devrient.
...
You don't need a 10€ printed in N for Y? = He asks if there's a need for a 10€ note printed in Bank of Greece for Greece.
I hope this makes sense..
