Ensure that you enter your address correctly in the boxes provided. Many users are adding information like country, state or postal code when not prompted to do so, leading to their verification application being denied. For reference, see below:
Address Line 1 is for the street address and has to be the same as stated on the provided documents.
Address Line 2 is for the apartment, suite or space number (or any other designation not literally part of the physical address). This is also optional and can be left blank if you are not sure what to enter.
