# Region

Similar to an [address question](/adding-questions-and-content/question-reference/address.md), the **region** question allows collecting location data, but does not require a street address.

Sometimes you might not want to collect an address, but just a region where a responder is interested in or living. A good example would be if you're collecting information about where a responder might be looking to rent or buy a property, without knowing where exactly. That's what the region question is for!

## Autocomplete using Google Places API <a href="#autocomplete-using-google-places-api" id="autocomplete-using-google-places-api"></a>

Providing a Google Places API key will allow autocompleting the remainder of the address parts from the value that the responder types into the first field.

### Guessing the postal code

Most larger towns and cities in the United States have more than one corresponding ZIP code. Consequently, autocompleting a string like "brooklyn" is ambiguous when it comes to ZIP code.

If you need ZIP code, you can enable the **Guess postal code?** option. Guessing the ZIP code results in a geolocation call being made to the Google Maps Javascript API, to find the ZIP code as close to the center of the region as possible, if one exists.

{% hint style="info" %}
Your API key must permit the **Maps Javascript API** and **GeoCode API** in addition to the **Places API** if using **Guess postal code.**
{% endhint %}
