Below are some frequently asked questions about t.co, Twitter's link-shortening service.
Links shared on Twitter.com will automatically be shortened to a http://t.co link. Learn how to shorten links here. Please note: t.co links are neither private nor public; anyone with the link will be able to view the content.
If the URL of a site you manage has been flagged, please see this help page about flagged URLs for more information.
Because of the reasons listed above, Twitter will shorten URLs you post on Twitter.com. You cannot opt out of link shortening.
If you want to shorten links to share with others, please see this help page on using URL shorteners. You can continue to use a URL shortener to shorten links, and tracking metrics (like those from bit.ly) will continue to work as they did previously. The link service at http://t.co is only used on links posted on Twitter.com and is not available as a general shortening service on other apps or sites.
