I highly doubt they would go to the trouble of reporting if it is not reporting now. Furthermore, the date of first deliquency is always going to be 2003, so it is too old to report. They cannot legally change that date. If it were to show up, I hope you have their contact info. And good for you paying them. It should feel good to be honest, and it should not come back to bite you in the rear.
