2000 Honda Civic EX - Radio Code

I was in need of obtaining a code to the radio for this car. After talking to the dealer, I learned that I needed to provide them with a radio serial code so they could provide me with a code. In this case, the seial number for the radio was m98d350329. The radio code resulted in 35446. I know that every car is different, but I just wanted to document the process for next time...
