Citizenship and A number and the address

[nichka]

Hi!
I have two questions.
1. I currently filling out forms to petiton my relatives and there is a question with Alien number(those from a green card), that I had before I became naturalized citizen. Do I need to use my A number now on forms or it is for permanent residents only? I am a citizen now.
2. I'm confused what address I need to use to send these forms. I'm submitting the following forms:
I-130, I-485, I-765, I-864, G-325A.
The instructions on I-130 says to use this adress:
PO Box 804616
Chicagi, IL

...the instructions of I-485 says to use:
PO Box 805887
Chicago, IL

Thank you very much for your help.

You do need to give them your former A number because that is what they will use to retrieve your file. Use the address for the I-485.

She is filling petition for her relatives as United States citizen not as an alien. Would it be logical for her to provide Naturalization Certificate number rather then former Alien number?

For what purposes USCIS need to retrieve US citizen “file” with former A number?

Definitely give them the A file number. The A file has all of her previous filings, including all prior instances where she referenced relatives. Many people "find" brothers and sisters after they naturalize. The CIS wants to make sure that the new petition information matches what was given previously.
