Once upon a time Vivastreet used to let you search by pretty much any post code. You'd start typing "Manch" (for example) and a drop down would appear listing pretty much all postcode areas in Manchester.
Now it limits the results to a select few post code areas. I'm looking for M4 postcode and I get M8, M21 - nothing that is of any use.
I've tried for other towns too - and the results seem to be limited.
Does any one have a workaround? I've tried just putting in M4 but it gives me half the country
