I-130 passport number

[Lira2]

I'm currently filling out my i-485 and i'm confused as to which passport number I use to fill in. I have my old one that is expired (2001-2011), that was used when I first came to the US and has my original visa, and a current one 2013-2018 that is just new/unused. Which passport number do I use to fill in this form? Thank you

Use the current passport, however keep your old 1 handy as you will need your I-94 entry stamp and entry number.
