I am not sure, if anybody has mentioned this or not, but I was able to find out which service center is processing my petition without calling the USCIS and before receiving the hard copy of NOA1. At this point, I only got a text from USCIS with a receipt number (IOE number).
I used USCIS Emma and got connected to a live rep through their chat. I gave the rep all the required information (Receipt number, full name, DOB, full address) and told the rep "I would like to find out what service center is going to be processing my I-130, so I can estimate my wait time." The whole process, including the wait time, took only about 10 mins.
I know that you can get all this information by patiently waiting for the NOA1 hard copy, but I just wanted to put the information out there for impatient people like me 😋
