How to remove my facebook main number

If you have been on Facebook recently, you may have seen a few of your friends update their status with this warning:

ALL THE PHONE NUMBERS of your contacts are now on Facebook! Go to the top right of the screen, click on ACCOUNT, click on EDIT FRIENDS, left side of screen and click CONTACTS. You will see all phone numbers from your phone (FB friends or not) are published that you have stored in your mobile phone. TO REMOVE, go to the right column, click on 'this page.' Please repost this on your status, so your friends can remove their numbers and thus prevent abuse if they do not want them published.

This isn't the first time that Facebook has published personal information about its users, and I don't know how recently this change to sync phone contacts, too, took place. But I can tell you that on my Phonebook Contacts list (Account > Edit Friends > Contacts), many but not all of my Facebook friends' phone numbers--both mobile and sometimes home--are listed. According to Facebook, this Phonebook "displays contacts you have imported from your phone, as well as your Facebook friends." Below this quote in the right-hand column of the Phonebook page, it offers instructions and a link to disable this feature and remove your mobile contacts.

That's all well and good, but unless all of my Facebook friends disable this feature, my number will still be out there, in the Facebook ether. In this tutorial, I will show you how to delete your phone number. And if you'd like, how to delete those of your Facebook friends as well.

I am an iPhone user, and I certainly didn't voluntarily provide my cell phone number to Facebook. (Just because I am Facebook friends with someone doesn't necessarily mean I want them calling me.) I don't know for sure, but I'm guessing my number got added when I installed the Facebook app on my iPhone.

To delete your phone number (or see if your number is listed), log in to Facebook and click the gray Edit Profile button in the upper-right corner of your profile page. Then, in the left-hand column, click on Contact Information. In the area labeled Phones, you'll see any numbers you've registered with Facebook, perhaps unknowingly. Remove any numbers you see there and click the blue Save Changes button below.

 

To delete your friends' phone numbers from Facebook's Phonebook Contacts list, click on Account in the upper-right corner of Facebook and then click on Edit Friends. Next, click on Contacts from the left-hand column and you should see many of your friends' phone numbers on the Phonebook Contacts page. In the right-hand column, Facebook provides a description of the page and how to remove your mobile contacts. Click on the linked words "this page" and then on the next page, hit the Remove button.

On the Remove page, Facebook says, "Before you click Remove, you need to make sure syncing is switched off" and gives instructions on how to find syncing on an iPhone.

To do so, open the Facebook app on your iPhone. From the main menu, tap the Friends icon, then the Sync button in the upper-right corner, then the Sync Contacts button, and then next to Syncing move the slider to Off.

Number to facebook help center

Unfortunately, there is no way to directly contact Facebook–you can't call, text, email, or otherwise speak to an employee or affiliate of Facebook. You can, however, use Facebook's Help Center to diagnose and report a problem with your account.

Method 1

Using Facebook Resources

1. 
   1
   Open the Facebook Help Center webpage. If you aren't already logged into Facebook, you'll need click the Log In button in the top right corner of the page to enter your Facebook email address and password.
2. 
   2
   Review the options toolbar. This is at the top of the screen, directly beneath the search bar--you'll need to drag your mouse cursor over each option to view its subsections. Your options include the following:

   • Using Facebook - This section of the Help Center covers basic Facebook functionality, including how-tos on friending, messaging, and account creation.
   • Managing Your Account - Covers items such as your login and your profile settings.
   • Privacy and Safety - Addresses account security, unfriending people, and hacked/fake accounts.
   • Policies and Reporting - Covers basic reporting (abuse, spam, etc.) as well as handling a deceased person's Facebook account and reporting hacked or fake accounts.
   • You can also check out the "Questions You May Have" and "Popular Topics" sections on this page, since they cover common issues and complaints.
3. 
   3
   Select a relevant section. For example, if you're having a problem with an impostor account, you'd select the "Privacy and Safety" section and then click Hacked and Fake Accounts.
4. 4
   Review additional options. In keeping with the impostor account example, you might click the "How do I report an account that’s pretending to be me?" link. Doing so will bring up a series of steps that explain how to remedy your situation.

   • For example, Facebook recommends dealing with an impostor account by going to the account's profile page, clicking ..., and clicking Report, then following the on-screen instructions.
5. 5
   Use the search bar to expedite your process. To do this, simply click on the search bar at the top of the Help Center page--it will say something like "Hi (Your Name), how can we help?"--and type in a few words related to your complaint. You should see several suggestions pop up in a drop-down menu below the search bar.

   • For example, you might type in "impostor account", then click on the "How do I report an account for impersonation?" result.
   • The search bar here only links to Facebook's pre-written articles--if you're looking for an answer to a specific issue not covered in the Help Center, skip ahead to the Community page.
6. 6
   Open the Ads Help Center page. If your business or page is having issues with ads, your questions are usually addressed in this section.

   • To delve into advertising, you'll want to click Creating Ads or Managing Ads.
   • For problems with advertising, you'll need to click Troubleshooting Your Ads and then select an issue on the subsequent menu.
7. 7
   Visit the Facebook Community page. If you can't find your current problem listed anywhere in the Help Center, your best bet is to look for it in the community forums here.

   • You'll see a search bar at the top of this page--you can look up topics (e.g., disabled accounts) from here.

How can you find someone phone number on facebook

Many Facebook users may not even realize that their private phone number is connected to their Facebook account, having forgotten that they did so. Facebook isn't allowed to simply extract your number from your phone, but they can do what I refer to as the "app equivalent of cyberbullying" by repeatedly asking you to confirm and save your number each time you launch Facebook.

The default privacy setting on Facebook allows anyone to search for you by your phone number once you add it. This is not a new issue.

Certainly, some people, such as celebrities and politicians, should be more concerned than others about revealing their private number online. However, anyone could potentially have a cyberstalker or hacker target them. Once a hacker has a phone number and your name, they can quickly use open-source intelligence (OSINT) tools that we've covered on Null Byte to grab further public data like occupation, employer, spouse, relationship, any other public info.
A hacker could use the information to further social-engineering attacks by calling you directly. Think of the classic " Microsoft tech support" scam, only the caller trying to trick you knows your name and intimate details of your personal life. Armed with these, it's easy to make the target think the caller is legitimate.

How would a hacker actually go about finding your number? In theory, if they had a lot of time, they could just search all 9,999,999,999 potential numbers until they stumbled upon yours. Clearly, this isn't very efficient, so let's see the right way of doing it. For a practice subject, I'll be using DC Mayor Muriel Bowser (2017) as a random city official. In the examples below, her number was changed to protect her real number.

Step 1 Use the Area Code

If you think of a target's phone number as one of all the possible 10-digit US phone numbers, you can quickly see that 10 billion North American phone numbers it far too large a list to effectively search through. Luckily for the hacker, he can cut this down thanks to the North American Numbering Plan (NANP) which lays out the guidelines for phone numbers in the US.
Let's take an example: 234-235-5678. Looking at the NANP, we can see that the first three numbers (234) are the area code, and the plan allows for 2–9 as the first digit and 0-9 for the second and third digits. That information right there eliminates one billion possible numbers from the hacker's list.
The hacker can also quickly take advantage of this if they know or can take an educated guess at where you live, as it's as easy a Google search. By doing this, the hacker can remove a further 9 billion 990 million numbers from the list of potential guesses.

The next three numbers after the area code in our example (235) are the central office prefix. Again, the plan calls for 2–9 for the first digit and 0–9 for both the second and third digits, but with a caveat.
In area codes where the second digit is 1, the third can't also be 1. This yet again removes a large number of phone numbers from the hacker's list. The last four digits of the phone number is the line number, in this case, 5678.

I took the educated guess that the Mayor of DC would have a DC area code, and a hacker could also look up the target's Facebook account and likely find a hometown or the current city the target lives in or works from. Some larger cities like Los Angeles will have multiple area codes within them, but no matter how many "split" area codes there are, it still greatly reduces the hacker's list of possible numbers.

Step 2 Get the Last Numbers

Now that I know my target's number is 202-???-????, I want to try and remove as many of those question marks as possible, making it easier to do a Facebook search later on. Thankfully, Facebook has our back and has made this probably the second easiest step, after using the area code. In order to get the last two numbers, we just have to go a few steps into the password reset process.
To do this, the hacker goes to the main Facebook page and clicks "Forgot account" to start the process.

Next, they enter the target's name they have in mind and click the "Search" button.

The hacker is then presented with a list that includes a face picture paired with each matching account that helps them quickly identify their target. There's our target right at the top!

Facebook then kindly provides the hacker the last two digits of the targets number, along with some information about the emails accounts associated with their Facebook account, such as the first and last letter, and sometimes the email domain.

That's as far as the hacker has to go. They don't actually reset the password, and they shouldn't so that the target never receives any kind of notification to tip them off.

Step 3Use Outside Sources

With over 218 million users, PayPal and other services can help add to the information the attacker has collected so far. In this case, if the target is a PayPal user, the hacker can get two additional digits of the phone number we're looking for.
In the picture above, you may have noticed that the first email listed is a Gmail account that starts with "M" and ends with "R."
That's funny, since my targets first name starts with an "M," and her last name ends with an "R." To a hacker, this screams "I used my name as my email!" Suspecting this was the case, I checked it on Gmail by typing it in.

Google accepted it, but that doesn't necessarily mean that it's the target's email. The hacker can check by doing the same password reset trick they pulled with Facebook.

Yep, this account just so happens to have a number that ends in 69. Coincidence? I think not. Now that I have an email to work with, I can jump over to PayPal in a new tab, and once again, use the same password reset trick.

This time, when I get to the password reset screen, I get not only all four digits of the line number, but also the first number of the area code too!

This allows me to be reasonably sure that I'm on the right track with the area code, and verifies my previous work on finding the last few numbers. This means I have the number 202-???-6969 so far. In other words, my list has gone from 10 billion choices to about a thousand in just a few minutes of work.

Step 4 Brute-Force It the Smart Way

At this point, a hacker could just start throwing numbers into the Facebook search bar, but that still wouldn't be that efficient. So what does a lazy hacker do? They take advantage of a Facebook feature that allows you to conduct a bracket search.

Facebook allows you to upload lists of contacts in CSV format, and then tells you if they are on Facebook so you can add them as friends. By constructing my own contact list of potential numbers, I can quickly rule out large chunks of wrong numbers.
In this case, I know the number has to be in the range from 202-000-6969 to 202-999-6969. By cutting that in half and creating a list of numbers from 202-000-6969 to 202-500-6969, I can effectively rule out half of my list, as the target will only be in one of the two half lists created. Then, I can upload the list and instantly determine if they are on it or not.
To create this list, I went to Google Contacts and clicked "Export" to get a sample CSV file to work from.

Facebook prefers to accept the list in Google CSV format, so I saved it as such from Google Contacts.

From there, a hacker can open the file in Google Sheets or Excel and change the column formula for the phone numbers to one that will iterate over the numbers they need to check, as seen in the following example.
In the excel formula below, I start by taking the lowest value phone number, in this case, 2020006969, then I add 10,000 to it in order to increase the fifth place digit by 1. This formula will repeat as many times as needed, but we shouldn't do it more than 1,000 times because there are only a thousand numbers in our list to guess. If the target hadn't had a PayPal account to help us derive the third and fourth place digit, then we would be adding 100 to increase the third digit instead.

=(ROW()*10000) +2020006969

From there, it is simple to sign into a Facebook account and go to the Friend Finder feature. Click on the Gmail logo and then "Find Friends."

Next, scroll to the bottom of the page and upload your CSV file containing the phone numbers you wish to try.

After it's uploaded, Facebook presents the hacker a list of "Friends" to add from the list. They would then search for their target inside that list. My target doesn't seem to be here, so I know they aren't in this half of our batch of numbers.

Next, instead of testing the next 500, I split the next 500 in half and check one of those halves. This is because I already know the target will be on the second list since they weren't in the first half. The hacker can continue searching in this way until the target appears on a phone number list.

From there on out, the hacker would test smaller and smaller batches of numbers until they have only a handful to test. I stopped when I had it down to about 30 numbers. Obviously, this will take longer if the hacker has less information about the other digits of the phone number to begin with, as they will have a larger number set to search. Facebook will rate-limit the hacker to five attempts per day but they can get around this by signing into another account.

Step 5Test the Last Few Numbers

Once that hacker has it down to a handful of numbers, they can go to the Facebook search bar and type them in one by one. To do so, just type the number into the search bar with no hyphens. If the requests are going too fast, or if they search for too many, Facebook starts to rate-limit them with a CAPTCHA.

However, that's not much of a defense when the hacker only has 30 numbers to check.

In total, it took me around 30 minutes to an hour to find the target's number, and these same steps could be used on anyone who has their phone connected to Facebook.

Step 6Protect Yourself

The simplest way to protect yourself is to never connect your phone to Facebook. If you still want to use two-factor authentication, Facebook allows you to use a USB U2F device without having to rely on your phone.
If you absolutely must have your phone connected, navigate to Facebook Settings, select "Privacy," then "Who can look you up using the phone number you provided?" Set this option to "Friends." Unfortunately, Facebook doesn't let you set this to "Only me."

On a mobile device, you would tap on the three-line menu icon, select "Account Settings" (iOS users will have to select "Settings" first), then tap on "Privacy." You'll see the same "Who can look you up" question above where you can change your preferences to "Friends" only.
