UK PostCode to Area Code

[Anonymous]

Hi,

I would like to break down the UK postcode into an area code. For example, SE27 9HR to SE27. 

I found a solution for a DAX command to return the first 2 characters (in this case SE) but I'd like the number as well. This was the solution: 

POSTCODEnew =
IF (
    RIGHT ( LEFT ( 'UK Post Code'[POSTCODEold], 2 ), 1 )
        IN { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" },
    LEFT ( 'UK Post Code'[POSTCODEold], 1 ),
    LEFT ( 'UK Post Code'[POSTCODEold], 2 )
)

Also, some postcodes have 3 characters at the start instead of 4 e.g. E14 0RW. So is there a DAX command to return whatever is in front of the break between the 2 sets of characters.

Hello there @Anonymous ! Wouldn't it be easier for you to do this in Power Query Editor with either the "split column" function or the "extract" function? 

Alternatively, you can also try this!

ColumnB = 
Var FirstSpace = FIND(" ";'UK Post Code'[POSTCODEold]) 
Return 
LEFT('UK Post Code'[POSTCODEold]; LEN('UK Post Code'[POSTCODEold]) - FirstSpace)

Hope this answer solves your problem! If you need any additional help please tag me in your reply.
