I need the radio code for my 2003 Honda Accord EX V6

It's only available from your dealer. There was also a card in the car when it was first purchased with the code. You might also be able to get it from the Honda site if you've registered your vehicle.

If you think about it, if we could give someone the radio code, they could steal the radio and resell it. That would invalidate the reason for the code in the first place.
