Design logic for matching UK Postal Codes

Hi,

I have a list of persons in UK identified by a range of postal codes:

Person	Postal Code Low	Postal Code High
Person A	BR0 0AA	BR9 9ZZ
Person B	DA0 0AA	DA9 9ZZ
Person Z	SW1A 0AA	SW1Z 9ZZ

I want match that specific Person to specific opportunities IDs based on Postal Code, but my other file has a specific Postal code that would follow in the range between Low and High

Opportunities	Zip Code
Opportunity Y	SW1E 5DH
Opportunity Z	EC1Y 0RR

Output would like:

Opportunities	Zip Code	Person
Opportunity Y	SW1E 5DH	Person Z
Opportunity Z	EC1Y 0RR	Person X

Anyone have any idea/suggestion on how to solve?

thanks so much

Hi @Lucasvital

Sorry I got distracted with our Inspire Conference.

Please find attached a workflow that builds out all the possible districts and keeps the relevant low and high.

You should then be able to match to the district column and can ignore the incode (last 3 characters).

Is it always the 0 to 9 for the range? If so, I'm wondering if you could parse out the first three characters from the postal code and then just have

BR0

BR1

BR2

...

BR9

Then parse out the same in the opportunities and join on these characters. That way all that you would have to do is Generate Rows for each two digit postal code range so that they go 0 to 9

Not really, there are cases that the first set of digits is 2 or 4 instead of 3, below is the whole list of potential postal codes:

This outlines the approach that I was looking to use. I don't work with UK Postal Codes very often so there are probably other criteria that are important. Maybe this is a start?

Generally converting a range to a list of lookup values uses generate rows in a similar fashion to my previous comment so I'm not sure if you just need the rules to be a bit more flexible based on the possible combinations.

JoeS

Nice work @BrandonB for having a go with UK postcodes from over the pond 😉

From looking at your problem, it looks like you can just use the Postcode area? AKA the first and/or second letter as the matching criteria?

Not sure if that's due to you posting a more simple scenario though?

To do that you can create the area in a new field using the RegEx tool:

Edit:

I have just seen you split out after 9 in the district, so not as straight forward as matching on postcode area. I'll reply back with a working solution....

Hi @JoeS .

Wanted to follow up if you found another alternative and can share the working solution?

Thanks
