UK Post Codes Lookup & Form Speed


This Discussion is public


I have a field called PostCode and I'd like people in the UK to quickly select theirs.

BUT I'm very worried it's going to slow down my form.

You'll see it's an 86MB csv.

Any ideas on how best to do this so it doesn't slow people down or the form down with a large lookup?

I would use the Google address API. It's fairly easy to implement and works well with Formidable:

Using the API provides consistency with address formatting so you won't encounter spelling errors and the like.

Thanks for the pro tip! That's super neat.

Do you have any more info on how it implements with Formidable?

Where would I put that code?
Can you limit it to only postcodes within a country? (It seems the maps are worldwide)
