UK Postcodes for ITV Hub
When you first register for ITV Hub, it will require you to enter a UK postcode.
However, it doesn't seem to matter what postcode you enter either, as long as it's a valid UK one. (i.e. E17 3AA)
If you prefer to use another postcode than the example above, Doogal has a complete list here for your reference: http://www.doogal.co.uk/UKPostcodes.php
