AC Delco EGR Part Numbers Confusion

[Ski-me]

So, the original AC Delco EGR valve that I pulled off was: 17087194

I believe it was change or updated to part #:19210654

Both of these line up to 214-5073

So, I order it up from Advance Auto.....box arrives with the 214-5073 part number on it, as well as 19210654.

But when I pull the part out, it says:
19209958
120421

I've tried to look these number up but found nothing. Is this some new number or is the wrong part in the box?
