Failed Smog Test Because EO Number on CAT Not Visible

I had a "new" CAT installed by my technician about 3+ years ago. My last required smog check was for last year which I "passed" without any problems. This means that the smog technician was able to read and verify the EO number/date on my catalyst during the last smog inspection. I am certain that the reason why my catalyst EO number has been scratched off is from hitting an object (example: a speed bump and/or going to fast into a angled drive way). My mechanic who installed the new catalytic converter does not have the sales receipt. What are my options here since my car is a year 2000, I do not believe I need to pass a "emissions test", correct? I know that my catalyst is working correctly as it passed the last smog check. I also believe that a "scratched out" EO number on the catalyst is a very common scenario with many other people so there must be another feasible solution to this. Please let me know. Thank you, Tim.

Answer:		Since the implementation of the new STAR smog check program, smog stations are being very careful in ensuring vehicles are equipped with proper/required catalytic converters. The smog check technician will check your vehicle's catalytic converter EO numbers. The EO number must be visible. If it appears scratched off to a degree where it is no longer legible, the vehicle will fail the "visual" portion of the smog inspection. If you believe that the EO number on your 2000 Honda Accord's catalytic converter is scratched but should still be able to be read you may want to have a second smog station conduct and inspection. If they too are unable to read the numbers you have the option of getting a smog inspection from a California smog check referee office. In any case the technician must be able to read the EO number in order to determine the CAT is designed for use on your specific year, make and model vehicle. A vehicle having passed a prior inspection is not proof that its current smog components are California legal. 2000 and newer vehicle still require smog inspections except they are not administered the tailpipe portion of the smog test. A 2000 and newer vehicle must pass the visual and functional  portion of the smog inspection only.
