Living at different address compared to AR-11


Registered Users (C)
I am renting an apartment and moving around in the same city, to avoid frequent address changes while applying for i485, I gave my friends home address who owns a home. Also submitted AR-11 with that address, I did not submit another AR-11 even after moving to another apartment, to make sure USCIS will have only one address on file. I live 10 min away from my friend.

Now 5 years passed after receiving GC, I want to file for Citizenship.

In N400 address column which address I should write? Whatever I stated in AR-11 (my friends home), or my physical address?

IRS, Banks, Utilities, Employer all have my current physical address.
