Check Facebook ID before adding friends on Facebook
Adding friends on Facebook is a basic action for many companies and individuals to do social traffic, user development and private domain construction. However, many people often encounter problems such as failure to add, adding the wrong person, unresponsive account, and restricted friends during the operation process. The root of the problem is often not adding the action itself, but the lack of clear identification of the target user before adding it. If you want to improve the success rate of adding and avoid wasting operational resources, a very practical action is to do a Facebook ID query first, and then perform number screening and status detection.
