How to add your location to a Tweet
Note: Enabling this feature allows Twitter to show the location you are Tweeting from as part of your Tweet.
You can choose to add a location to your Tweets using Twitter for Android, Twitter for iOS, twitter.com or other mobile applications. For example: To give additional location context to your Tweet, you can add a general location label such as “SoMa, San Francisco." In select locations, on Twitter for iOS and Twitter for Android, you may also label your Tweet with the name of a specific business, landmark, or other point of interest. These locations are provided by Foursquare and Yelp.
If you are using Twitter for Android or Twitter for iOS, the Tweet may also include your precise location (i.e., the GPS coordinates from which you Tweeted), which can be found through the Twitter API, in addition to the location label you select. See below for more information.
Note: It is important to note that deleting location information on Twitter does not guarantee the information will be removed from all copies of the data on third-party applications or in external search results. Additionally, this setting will not remove locations shared through Direct Messages.
In some areas, you have the option to label your Tweet with a specific business, landmark, or point of interest. These places are sourced from Foursquare and Yelp. If you see an issue with a place provided by Foursquare, you can report it via Foursquare’s Help Center. If you believe that a specific Tweet is abusive, please report it to Twitter by following the instructions here.
