If we mail the N-400 forms and documents vis US Mail or Express mail, the mailing address is

Is it correct? Or is there only one mailing address for the application?

Thanks!
 
I used the 1st address and use DHL. Just make sure to put N-400 Application in the address.
 
I mailed my application to the first address however, I did not mention N-400 application on the address line.

Do I need to resend the application?
