Facebook stores your contacts in three separate places, and which one you use depends on what you're trying to do
Facebook keeps contact information in your Friends list, your Messenger contacts, and a separate Contacts tool that syncs with your phone or email. Your Friends list shows people you've already connected with. Messenger contacts include anyone you've messaged, plus suggestions Facebook generates based on mutual friends and your activity. The Contacts tool — found in Settings under "Your Facebook Information" — is where Facebook stores phone numbers and email addresses it has collected from you, your contacts' devices, or other sources.
Understanding where your information lives on Facebook matters because each location has different privacy controls, and what you see there may surprise you. Facebook often adds contacts without your explicit action, pulling from your phone's address book, email accounts you've connected, or inferred from your browsing and app use.
Key Takeaways
- Your Friends list, Messenger contacts, and the Contacts tool are three different places where Facebook stores people's information about you and your connections.
- Facebook syncs contact information from your phone, email, and web activity without always asking first, so the Contacts tool often contains people you never intentionally added.
- You can read a copy of all your contacts and the information Facebook has stored about them through the read Your Information tool in Settings.
- Removing contacts from Facebook does not delete them from your phone or email — it only removes them from Facebook's systems.
- Turning off contact syncing in your phone's settings stops Facebook from automatically uploading your address book in the future.
Finding your Friends list and seeing who you're connected to
Open Facebook and click your profile picture in the top right corner. Select "Friends" from the menu. This shows everyone you've sent a friend request to and who has accepted. You can search for a specific person by typing their name in the search box at the top of the Friends page, or sort by "Recently Added" to see who you've connected with most recently.
Your Friends list is public by default, meaning anyone on Facebook can see who your friends are — though they cannot see your private messages or posts you've limited to specific people. If you want to hide your Friends list entirely, go to Settings, click "Privacy," and change "Who can see your friends list?" to "Only me." This hides the list from everyone except you, though Facebook itself still knows who your friends are.
Checking your Messenger contacts and message history
Open Facebook Messenger (the separate app or the Messenger section within Facebook). Your Messenger contacts include everyone you've ever sent a message to, plus people Facebook suggests you might want to message based on mutual friends and shared groups. Scroll through the list to see who you've communicated with, or use the search bar at the top to find a specific person.
Messenger contacts are different from your Friends list — you can message someone without being friends with them, and Facebook will still record that contact. If you delete a conversation, the person remains in your Messenger contacts. To remove someone from your active Messenger list without deleting the entire conversation history, you can "Mute" the conversation (which hides it but keeps the messages) or archive it (which removes it from your main view but stores it separately).
Accessing the Contacts tool to see what Facebook has collected
Go to Settings (click your profile picture, then "Settings and privacy," then "Settings"). On the left side, click "Your Facebook Information." Look for "Contacts" — this is where Facebook displays phone numbers, email addresses, and other contact details it has gathered. This tool shows you what information Facebook associates with you and your connections, pulled from multiple sources.
Facebook populates this Contacts tool by syncing your phone's address book, importing contacts from email accounts you've connected (like Gmail or Outlook), and collecting information from websites and apps that use Facebook's login or tracking tools. You may see people in this tool you never intentionally added to Facebook. The Contacts tool is not the same as your Friends list — it can include people you've never messaged or friended.
Downloading all your contact information at once
To see everything Facebook knows about your contacts and your connections, use the read Your Information tool. Go to Settings, click "Your Facebook Information," then select "read Your Information." Choose the date range and data types — select "Contacts" to read a file containing all the contact information Facebook has stored.
Facebook will prepare a file (usually in JSON or CSV format) that you can read to your computer. This file shows phone numbers, email addresses, and other details associated with your contacts as Facebook has recorded them. The read can take anywhere from a few minutes to several hours depending on how much data you have. You'll receive a notification when it's ready, and you can read it from the same page.
Removing contacts and stopping automatic syncing
To remove a contact from Facebook's Contacts tool, go to Settings, click "Your Facebook Information," then "Contacts." Find the person you want to remove and click the X or delete button next to their name. This removes them from Facebook's contact list but does not delete them from your phone or email — it only removes them from Facebook's systems.
To stop Facebook from automatically syncing your phone's address book in the future, go to your phone's Settings (not Facebook's Settings). On iPhone, go to Settings, scroll to Facebook, and toggle off "Contacts." On Android, go to Settings, select "Apps," find Facebook, tap "Permissions," and turn off "Contacts." This prevents Facebook from uploading your address book without your action, though it does not remove contacts Facebook has already collected.
Understanding what information Facebook shares about your contacts
Facebook does not show your contacts your phone number or email address unless you've made that information public on your profile or shared it directly with them. However, Facebook uses contact information internally for its own purposes — to suggest friends, target ads, and build profiles of people who are not yet on Facebook.
If someone has your phone number or email in their phone and they sync their contacts with Facebook, Facebook may create a "shadow profile" — a record about you that exists on Facebook's servers even if you do not have a Facebook account. If you later join Facebook, your account may be linked to that shadow profile. This is why you may see friend suggestions for people you never told Facebook about.
Frequently Asked Questions
Can I see who has added me as a contact on their phone?
No. Facebook does not tell you who has synced your phone number or email address from their address book. You can only see the contacts you have added or that Facebook has collected about you. You cannot view the reverse — who considers you a contact.
What happens if I delete someone from my Messenger contacts?
Deleting a Messenger conversation removes it from your active list, but Facebook may still retain the message history on its servers. The person remains in Facebook's records as someone you have communicated with. If you want to remove someone from your Messenger suggestions entirely, you can block them, which prevents them from messaging you and removes them from your active contacts.
Why does Facebook show me contacts I never added?
Facebook automatically syncs contacts from your phone's address book, email accounts you've connected, and infers connections from your web activity and app use. You may also see suggestions based on mutual friends, shared groups, or networks. This happens without explicit action on your part — syncing often happens by default when you first install the Facebook app.
If I remove someone from my contacts, can they still message me?
Yes. Removing someone from your Contacts tool or Messenger list does not block them or prevent them from sending you messages. It only removes them from your view. If you want to prevent someone from contacting you, you need to block them separately — go to their profile and select "Block."
Does turning off contact syncing delete contacts Facebook already has?
No. Turning off contact syncing in your phone's settings stops Facebook from uploading your address book going forward, but it does not remove contacts Facebook has already collected. You must manually remove them from the Contacts tool in Facebook Settings if you want them deleted from Facebook's systems.
