Address Autocomplete

Question

Hello everyone and thanks for the help in advance. I need to develop a page for address input that will be entered by an end user. Obviously, user input is prone to error so I am looking for solutions to validate the input. I know the US Postal service has an api to validate against, but I am also aware sites like Zillow use some type of autocomplete for the input. I'm not sure what the best method is and there seems to be numerous for-pay autocompletes. Any insight would be appreciated.

Hi @Kmcnet ,

I think you can autocomplete addresses in ASP.NET MVC using Google Places AutoComplete plugin.

The Google Places (Address) AutoComplete TextBox is part of Google Maps API and it is used to find out Address and their Geographical coordinates i.e. Latitude and Longitude of a Location.

You can refer to the following example:

Hi @Kmcnet,

Great question! I've run into the same issue while building address input forms—user-entered data is often incomplete or messy, and getting clean, standardized addresses can be tricky.

I’ve recently been using Sthan.io, and it’s been a solid alternative—especially for .NET projects. It's a lightweight, developer-friendly set of APIs for address autocomplete, parsing, and validation.

If you want to see it in action: US Address Autocomplete

Docs are here: Sthan.io Documentation

Hope this helps!
