If it does, it is written on the bottle. That is a good question.  I know that I have used bottles that I have kept around for years (mostly on my dogs when the get skunked). I think hydrogen peroxide is very stable and can last for a long time in a sealed bottle, but if you are ever in doubt, just buy a new one. It is also very inexpensive.
