A usual recommended limit is 20 friend requests each day, however some users have reported being barred by Facebook for sending fewer than that, while others have successfully sent more. There is no way to see how close you are to the limit; it's up to Facebook when it will block your account.
In general, try not to send too many friend requests at once. If you receive many friend requests but don't know who they are from, it's best to wait before accepting or rejecting them so as not to violate any limits.
However, there are several reasons why you might want to send lots of friend requests at once. For example: if you are trying to get more visibility for your page or group, then messaging many friends at once is a good way to do so. You should also consider sending friend requests if you have many friends who have not yet accepted your invitation (or rejected it if they already were your friend). In this case, sending a large number of requests at once will help you reach more people faster. Finally, you may want to send a lot of requests if you are trying to convince someone else to join your network.
In any case, keep in mind that Facebook limits the number of friends you can have at one time.
Aside from the 5,000 friend limit, there is no declared restriction to the amount of friend requests you can send every day. There is, however, a limit to how many outstanding, ignored friend requests you may have at any given moment.
Second, the amount of friends that any particular profile can have is strictly limited. The hard cap is 5,000 individuals. When you reach 5,000 friends, Facebook determines that your social circle is complete and disables your ability to add new friends.
On Facebook, you can send up to 20 friend requests every day. This limit is based on what information Facebook has about you. If they believe you're not a human being, the limit goes up to 100 per day.
The limit applies to both your personal and business profiles. However, only one of these profiles can be active at a time. So if you want to send 100 friend requests today, you'll have to log out of one profile and into the other.
If you try to send more friend requests than this, Facebook will show you an error message saying "You've sent too many friend requests - please wait until you've sent at least one request before sending more."
However, there is no actual limit to how many friend requests you can make from your own account. That limit is based on Facebook's policy of limiting the number of connections any one person can have with other people. But since you're asking here, we can assume that you have permission from all of your requested friends to send them requests. If they don't give you permission, then you couldn't send more than 20 requests even if you tried very hard!
Facebook users have a friend request queue limit of roughly 1,000 and a verified friend limit of 5,000. Exceeding these limits may cause your requests to be rejected.
Facebook allows a limit of 5,000 connections, including friends and page likes. This limit is applied per account. If you reach this limit, your account will be unable to add any more friends.
However, there is no limit to what type of relationships you can have with these 5,000 people. They can be colleagues, family members, acquaintances, etc. The only restriction is that you cannot connect them to your own profile. If you try, an error message will appear telling you that too many connections are already in place.
It's also important to note that removing someone as a connection does not remove their relationship with you. It simply removes the connection from one side of the equation only. To delete the person from your list of friends, you must also delete them from all other devices/platforms where they might still appear.
In addition, Facebook has announced that it is going to start limiting old email addresses that are used by existing users. Any address that was valid six months ago could potentially be affected. If you haven't changed your default email address yet, it may be a good idea to do so soon as possible.
[Updated for 2021] "This individual has hit their friend request limit and is unable to accept any more requests." Facebook users have a friend request queue limit of roughly 1,000 and a verified friend limit of 5,000. Insiders (Facebook personnel) claim that larger accounts have technological challenges, which is why they are limited.
The greatest thing that existing Facebook users can do is limit who may locate them using their phone number to only their friends. This is how. Tap the hamburger symbol on the mobile app and go to Settings & Privacy > Settings > Privacy Settings.
