PP Stamping - Question

Registered Users (C)
We got our Passports Stamped in Boston today. Our I-485 was approved from CSC and we were asked to go to San Jose. We did not have any problems getting it stamped in Boston (as we live here). They did ask why we came here and asked proof of residence here.

They filled the form for I-551 (took fingerprint and signature) and wrote the A-number on it. We didnt get any case number or anything for tracking the card status later. Is the A-number sufficient to do that?

Thanks.
