Inward code max length

[ChappersJr]

Hey,

I've come across a potential issue with the Inward code for a United Kingdom postcode.

From what I've researched the length of the inward code is 3 characters.

Using this example: NN1 5LLL

Even though it's an invalid postcode (inward code being 4 characters long), it gets passed validation.

Hello @ChappersJr, thank you for your bug report, I just tested this and I think you're right (I'm not from the UK myself so I'm not particularly knowledgable about UK postal codes)

Your example does indeed match, wrapping the pattern does seem to fix the issue, but I will need to run some tests to make sure nothing else breaks because of this change

@ChappersJr please take a look at the change, I think this should fix the issue
