Stupid Question concering Addresses in Great Britian

I have a niece that lives in Liverpool. I am trying to purchase her first birthday present from amazon so I do not have to ship the package myself overseas. So, the address is something like:

### Somename Court
Streetname Street East
Liverpool
L2 3AB

Amazon asks for Address 1, Address 2, Town/City, County and postcode.

Now I can figure out Address 1 and 2. I am pretty sure that the Town\City part is Liverpool.

However what part of L2 3AB is the the county and postcode?

I know this is probably a stupid question but I have never sent a package overseas.

Thank you for your help.
