If you want to pre-fill the Zip Code into your booking form, you can do so by adding a querystring parameter (i.e. “?zip=myzipcode” ) to your booking form link.
For example, my booking form is installed on a page like this:
If I want my zip code ‘12345’ to be pre-filled into form, I would add “?zip=12345” to the end of my link:
Now when somebody clicks that link on my site, the zip code will be pre-filled into the form for them.
Note: If you have already added parameters to your link, use “&zip” instead of “?zip”.
