How can I tell INS has my current address?

I moved one year ago while I was waiting for my green card. I file a change of address form last July. I believe it was sent to the regional office and not the Washington office. I received my green card 6 months ago sent to my current address. Can I use this as proof that my address is current with the INS?

Thanks.
