This is similar in structure to the serial, this is like the Title ID in the sense that it is a per title Identifier, but it is not checked by the 3DS Applications (It's like an internally used name). And follows this structure:

CTR-[P/N/T]-[Type][Identifier][Region]-[Region]-[Digit]

CTR-[P/N/T/U]-[Type][Identifier][Region]

* P/N/T/U - P  Generally used for card based games (& Digital Download versions) / N Used for built in applications like [[Mii Maker]] and some eShop titles / T is used in some e-Shop demos / U is used for [[Title list#0004000E - Add-on Content (Updates)| Add-on Update Data]]

* [Type][Identifier][Region] - Same as in Serial structure

So for example a Japanese copy of Ridge Racer 3D would have a Product Code of "CTR-P-ARRJ" and a Serial of "LNA-CTR-ARRJ"

Some eShop titles have Product Codes which differ from the above format:

'''NOTE:''' The Product Code "CTR-P-CTAP" is the default Product Code for NCCH files. So where a Product Code isn't assigned, this Product Code is usually used.

* [Type][Identifier][Region] - Same as in serial structure

Some eShop titles have [[NCCH#CFA|Electronic Manuals]] which store the product code at the end of the 'Health & Safety' section of the 'Manual'. However  Product Codes can which differ from the above format as shown below:

* [Region] - Same as in normal Product Code structure

* [Digit] - Same as in normal Product Code structure

Note: the additional [Region] and [Digit] identifiers aren't present in the actual Product Code, as found in the game's CXI. They are only found in the game's Home Menu Manual, and on the game's packaging/external labeling.

CTR-[P/N/T/U]-[Type][Identifier][Region]-[Region]-[Digit]

The Product Code "CTR-P-CTAP" is the default Product Code for developers.

CTR-[Type][Identifier][Region]-[Region]-[Digit]

 

* P/N/T/U - Same as in Product Code structure

* [Region] - A three character representation of the title region, i.e. 'EUR' (Not always present)

You can check the product code at the end of the 'Health & Safety' section of the 'Manual' of your application in the Home menu.

'''Note:''' These alternate versions of the Product Code, potentially found in [[NCCH#CFA|Electronic Manuals]] don't represent the actual Product Code, as found in the game's CXI. They are only found in the game's Home Menu Manual, and on the game's packaging/external labeling.
