If you use Facebook, you may already know that it allows you to sync Facebook contacts with iPhone, making it easier to call or message your Facebook friends directly from your phone. While this feature is convenient, many users-especially those new to it-are unsure how to sync Facebook contacts with iPhone correctly.
In this guide, we'll explain how to sync Facebook contacts with iPhone using the built-in method and introduce three reliable third-party tools. You'll also find helpful tips to avoid common issues and ensure your Facebook contacts sync smoothly to your iPhone.

iPhone offers a simple built-in method to sync Facebook contacts with iPhone through the Messenger app. After installing Messenger on your device, you can easily import Facebook contacts by signing in with your Facebook email and password. If your login information is incorrect or forgotten, the syncing process may fail. Follow the steps below to sync Facebook contacts with iPhone successfully.

If you no longer want Facebook contacts to sync with your iPhone, simply remove your Facebook account from the device to stop future updates. (How to Delete Facebook Messages on iPhone?)
If your device is running iOS 11 or an earlier version, you can sync Facebook contacts with iPhone directly through Settings. By signing in to your Facebook account on your iPhone, your Facebook contacts can be added to the Contacts app, and calendars can be synced as well. Follow the steps below to get started.

Tip: Because of Facebook and Apple's privacy policies and recent API changes, the official direct syncing feature may no longer be available.
Even though Facebook no longer supports directly syncing contacts to iPhone, you can still use a manual workaround to achieve the same result. This method involves exporting your Facebook contacts first and then converting them into a format that can be synced to your iPhone.
Step 1: Export Facebook Contacts

Step 2: Convert Facebook Contacts for iPhone Sync
Since Facebook only allows contact exports in HTML or JSON formats, these files cannot be synced to an iPhone directly. To resolve this, you can use an online file converter to change the exported data into XML format. Once converted, the file can be easily imported and synced to your iPhone in just a few simple steps.
Step 3: Import Facebook Contacts to iPhone
Coolmuster iOS Assistant is a professional iPhone contacts manager and iOS data management tool designed to help users transfer, back up, and manage iPhone data on a computer with ease. It allows you to import contacts to iPhone from various file formats, including XML files converted from Facebook contacts. With a simple interface and stable performance, it offers a practical solution for users who want to sync Facebook contacts to iPhone without relying on iTunes or iCloud.

If you don't want to rely on iPhone system settings, using dedicated apps is another practical way to sync Facebook contacts to your iPhone. These applications are designed to pull contact details from social platforms and merge them into your iPhone Contacts app with minimal effort.
Sync.ME
Sync.ME is a user-friendly app that helps you sync Facebook contacts to your iPhone quickly. In addition to Facebook, it supports syncing contact data from platforms like Twitter, LinkedIn, and Google contacts. The app can also update profile photos and other available contact details, making your contact list more complete and easier to manage.

FaceSync
FaceSync is a popular choice among users who mainly rely on Facebook for communication. It allows you to sync not only phone numbers, but also profile photos, birthdays, company names, and job titles from Facebook to your iPhone. This makes it especially useful for keeping professional and personal contact details organized.

ContactsXL
ContactsXL works primarily as a contact management tool for iPhone users, but it also supports syncing Facebook contacts. With this app, you can import phone numbers along with Facebook profile pictures into your iPhone Contacts. Having photos attached to contacts helps you quickly recognize people and access their information more efficiently.

Q1. Do all the methods in this guide support every iPhone model?
Not completely. Some older solutions, such as syncing Facebook contacts through iPhone Settings, only work on iOS 11 or earlier. For a more universal approach, you can export Facebook contacts to a computer and then import them to your iPhone using Coolmuster iOS Assistant, which supports most iPhone models and iOS versions.
Q2. How can I upload my phone contacts to Facebook?
Open the Facebook app on your iPhone or Android device, tap the three-line menu icon, and go to "Friends." From there, select "Upload Contacts" and tap "Get Started." After enabling contact uploading, your phone contacts will be synced to your Facebook account.
Q3. Will Facebook contacts stay updated on my iPhone automatically?
No. In most cases, contact information does not refresh automatically. If your Facebook friends update their details, you'll need to sync or import the contacts again to see the changes on your iPhone.
Q4. How can I disable Facebook contact syncing on iPhone?
Open the Facebook app and tap the three-line menu icon. Go to "Settings & Privacy" and then "Settings." Under the "Media and Contacts" section, tap "Upload Contacts" and switch the option off to stop syncing.
In this guide, we've explored several practical alternatives for syncing Facebook contacts to your iPhone when direct options aren't available.
