# Latitude/longitude support

**Element type:** Suggested

**Endpoints/models used:** [AddressesModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/AddressesModel/)

For US addresses only, if the host application captures GPS coordinates with addresses, then pass the latitude and longitude along with the address. This is especially useful in situations where a location or service site can only be pinpointed by geo-location.

You can add these values to your application using the `latitude` and `longitude` field in the [AddressesModel](https://developer.avalara.com/api-reference/avatax/rest/v2/models/AddressesModel/) at the header or line level. Refer to the earlier [Addresses in transactions](https://developer.avalara.com/avatax-for-ap/simple-transactions/addresses-in-transactions) topic for more information.

**View example**:

```
{
  ...,
  "addresses": {
    "singleLocation": {
        "line1": "2000 Main Street",
        "city": "Irvine",
        "region": "CA",
        "country": "US",
        "postalCode": "92614",
        "latitude": "33.684330",
        "longitude": "-117.850630"
    }
  }
}
