# How to control address name variants
<a name="how-to-geocode-address-names-mode"></a>

`AddressNamesMode` specifies how address names are returned. If not set, the service returns normalized (official) names by default. When set to `Matched`, address names in the response are based on the input query rather than official names. When set to `Administrative`, the service returns the official administrative names for address components. `Administrative` currently applies only to addresses in the United States.

## Potential use cases
<a name="geocode-address-names-mode-use"></a>
+ **Address form completion:** Use `Matched` to return names consistent with what the user typed, reducing confusion in autocomplete workflows.
+ **Address standardization:** Use `Administrative` to normalize city names to their official administrative form for data quality and deduplication.
