Datecodes are found on the sticker behind the battery on the PSP. They can be useful in determining information about the unit without taking it apart or running 3rd party software. For example if you are planning to get a specific motherboard and buy online where the seller provides no hardware info and you have to defer from a couple pictures.
In some cases the datecode is enough to know the exact motherboard/shipped firmware. If not additional information which can usually be found on the battery sticker--such as serial/part numbers and FCCID is enough. Other times it is impossible to tell without a program or taking it apart. It all depends on what region/model it is.
The datecode consists of one number followed by one letter: the number is the last digit the year it was manufactured and the letter is the quarter of the year. For example 5A would mean first quarter of 2005, 0C would mean third quarter of 2010.
- A = January/February/March
- B = April/May/June
- C = July/August/September
- D = October/November/December
Not all regions have datecodes--Japan doesn't have them for any model. North America only has them on Fat models up to 6C or so. Also this information doesn't seem to be present on the E1000 Street model. On the PSP Go it is on the back of the screen.
Serial numbers consist of two letters followed by 7 numbers: the first letter is the first letter of the place of manufacture (S=SKZ KISARAZU, F=FOXCONN, etc) and the next letter is the region it was manufactured for (J=Japan, U=US/Canada, etc). The 7 numbers are the actual serial number of the unit. It appears to be incremental with most models having a specific range, however some exceptions do apply. Most limited edition units (Star Wars, God of War, Madden 09, etc) have a specific range that deviates from the standard Piano Black units. For example PSP-2001 Star Wars are always HU7xxxxxx.
The top corner of the battery sticker just says "PSP" for TA-079 units. For TA-081+ this was changed to "PSP(TM) PlayStation(R) Portable". This is consistent with everything else in the product line being changed. Such as the gameboot logo and help screen in firmware 2.00, IDStorage USB, and instruction manuals.
The letter on the side of the PSP box (usually under model number) can determine what firmware the PSP shipped with. Some known dates are below.
