Can a form automatically fill out the 9 digit zip code based on the address one enters?

I have a client who's form asks for peoples address. It would greatly help the client if the form could somehow take the street, city, and 5 digit zip, and then add the remaining 4 digits of the zip based on the city and street. I'm thinking google maps would probably have to be involved with something like this, and not sure if this capability exists at all in a form. Does anyone know of a feature like this, either in jotform or maybe a widget? I googled the question but nothing came up, thank you for any suggestions.

Hi,

I'm not sure if I understand the function you are looking for correctly, but we do have a couple of widgets to where you can capture specific location details of the user, this includes coordinates, zip/postal code, exact address, etc...

You can check the following widgets that might help you:

1. http://widgets.jotform.com/widget/zip_code_auto-suggest 

2. http://widgets.jotform.com/widget/geocomplete 

3. http://widgets.jotform.com/widget/address_map_locator 

4. http://widgets.jotform.com/widget/autocompleted_address 

Most of the widgets are using Google Maps. I hope this helps. Let us know if you need further assistance on this.

Thank you.
