If you can't find your address on the drop-down menu, this might be because it's not on the Royal Mail database.
You'll need to check that your address is showing on Royal Mail postcode finder: http://www.royalmail.com/find-a-postcode
If you can't find it, it may be useful to contact the Royal Mail directly so they can add it for you. This will help us to find your correct address so we can match you to a credit report.
If you can find your address here, let us know the full address and we'll look into getting it added to Equifax's database for you.
