Unfortunately DELCO codes are not obtainable for free (using the Serial Number) from anywhere on the Internet as access is required to the original factory database which is only available to the Main Dealer or one the larger professional Decode Services.
The alternative is for your radio to be taken/posted to a Decode Service or your local Car Radio / Audio Shop who will plug it into a laptop and electronically read/recode the memory chip (EEPROM)
