Having trouble adding your friends or contacts on LINE? You're not alone! Many users encounter this issue, and it can be frustrating. This comprehensive guide will walk you through various reasons why you might be unable to add someone on LINE and provide practical solutions to get you connected. We'll cover everything from basic troubleshooting steps to more advanced fixes, ensuring you can successfully add your friends and enjoy seamless communication on LINE.

Understanding the Common Culprits

Before diving into specific solutions, it's crucial to understand the common reasons why you might be facing difficulties adding someone on LINE. Identifying the potential cause is the first step towards resolving the issue effectively. Here are some of the most frequent culprits:

  • Privacy Settings: LINE offers a range of privacy settings that allow users to control who can add them. If the person you're trying to add has restricted who can add them via ID or phone number, you'll be unable to connect using those methods. Understanding and adjusting these settings is key to ensuring successful connections.
  • Incorrect ID or Phone Number: A simple typo can prevent you from adding someone on LINE. Double-checking the LINE ID or phone number you're using is essential. Even a single incorrect digit or character can lead to a failed connection attempt. Accuracy is paramount when adding contacts using these methods.
  • LINE App Issues: Sometimes, the issue isn't with the settings or information but with the LINE app itself. Bugs, glitches, or outdated versions can interfere with the app's functionality, including adding contacts. Keeping your app updated and troubleshooting potential software issues is vital for smooth operation.
  • Network Connectivity Problems: A stable internet connection is crucial for LINE to function correctly. If you have a weak or unstable connection, you might experience difficulties adding contacts. Ensuring you have a reliable Wi-Fi or cellular data connection is a fundamental step in troubleshooting any LINE-related issue.
  • Blocked User: If you've been blocked by the person you're trying to add, you won't be able to connect with them on LINE. This is a privacy feature designed to prevent unwanted contact. Understanding how blocking works on LINE is essential for navigating social interactions within the app.

Troubleshooting Steps to Fix "Can't Add Each Other" Issue

Now that we've covered the common reasons, let's move on to the troubleshooting steps you can take to resolve the "can't add each other" issue on LINE. We'll start with the simplest solutions and gradually progress to more advanced ones.

1. Verify Privacy Settings

Privacy settings are often the primary culprit when you can't add someone on LINE. LINE allows users to control who can add them via their ID or phone number. If the person you are trying to add has disabled the "Allow others to add me by ID" or "Allow others to add me by phone number" option, you won't be able to connect with them using those methods. This is a crucial first step in diagnosing the problem. To check and adjust your own privacy settings, follow these steps:

  1. Open the LINE app and navigate to the "Settings" menu. This is usually found by tapping the gear icon on your profile page or within the "Home" tab.
  2. Scroll down and select "Privacy." This section houses all the settings related to your account's privacy and visibility.
  3. Look for the options "Allow others to add me by ID" and "Allow others to add me by phone number." Ensure these options are enabled (the toggle switch should be green). If they are disabled (gray), toggle them on to allow others to add you using your ID or phone number.
  4. If you're still unable to add someone, ask the person you're trying to add to check their privacy settings as well. It's possible they have these options disabled, preventing you from adding them.

By ensuring these settings are correctly configured, you eliminate a common barrier to adding contacts on LINE. This simple check can often resolve the issue quickly and efficiently.

2. Double-Check LINE ID and Phone Number

One of the most frequent causes of being unable to add someone on LINE is a simple typo or incorrect information. Double-checking the LINE ID or phone number you're using is crucial. Even a single wrong digit or character can prevent the connection from being established. This is a fundamental step in troubleshooting, and it's often overlooked.

  1. Verify the LINE ID: If you're trying to add someone using their LINE ID, carefully compare the ID you have with the ID they've provided. Pay close attention to case sensitivity, as LINE IDs are case-sensitive. A seemingly minor difference, such as a lowercase letter instead of an uppercase one, can make the ID invalid.
  2. Confirm the Phone Number: If you're using a phone number, ensure you have the correct country code and area code. A missing or incorrect digit can prevent you from adding the person. Double-check the number with the person you're trying to add to ensure its accuracy.
  3. Ask for Confirmation: If you're unsure about the ID or phone number, don't hesitate to ask the person you're trying to add to confirm the information. It's always better to be sure than to continue troubleshooting with incorrect details.

By meticulously verifying the LINE ID and phone number, you can rule out a common source of errors and ensure you're using the correct information to connect.

3. Restart the LINE App

Sometimes, the issue isn't with the settings or information but with the LINE app itself. Restarting the LINE app can often resolve temporary glitches or bugs that might be interfering with its functionality, including adding contacts. This is a quick and easy solution that can often work wonders.

  1. Close the App Completely: On most smartphones, you can close an app by swiping it away from the app switcher or force-stopping it in the device's settings. Ensure you're not just minimizing the app but completely closing it.
  2. Wait a Few Seconds: Give your device a few seconds to fully process the closure of the app before reopening it.
  3. Reopen the LINE App: Launch the LINE app again and try adding the person. Restarting the app clears any temporary data or processes that might have been causing the issue, giving the app a fresh start.

If restarting the app doesn't solve the problem, it indicates that the issue might be more persistent and require further troubleshooting. However, it's always a good first step to rule out temporary glitches.

4. Update the LINE App

Using an outdated version of the LINE app can lead to various issues, including problems with adding contacts. App updates often include bug fixes, performance improvements, and new features that can resolve compatibility issues and enhance the app's overall functionality. Keeping your LINE app updated is crucial for a smooth experience.

  1. Check for Updates: Go to your device's app store (Google Play Store for Android or App Store for iOS) and search for LINE.
  2. Update if Available: If an update is available, you'll see an "Update" button. Tap it to download and install the latest version of the app.
  3. Restart the App: Once the update is complete, restart the LINE app to ensure the changes take effect.

By updating the app, you're ensuring you have the latest bug fixes and improvements, which can often resolve issues related to adding contacts. If you're still facing problems after updating, move on to the next troubleshooting step.

5. Check Your Internet Connection

A stable internet connection is essential for LINE to function correctly. If you have a weak or unstable connection, you might experience difficulties adding contacts or using other features of the app. Ensuring you have a reliable internet connection is a fundamental step in troubleshooting any LINE-related issue.

  1. Test Your Connection: Try accessing other websites or apps that require an internet connection to see if they're working properly. If you're experiencing issues with other online services, it's likely a problem with your internet connection.
  2. Switch Between Wi-Fi and Cellular Data: If you're using Wi-Fi, try switching to cellular data, and vice versa. Sometimes, a particular network might be experiencing issues. Switching networks can help you determine if the problem is with your connection.
  3. Restart Your Router: If you're using Wi-Fi, try restarting your router. This can often resolve temporary connectivity issues.
  4. Move Closer to the Router: If you're using Wi-Fi, try moving closer to your router to improve the signal strength.

By ensuring you have a stable and reliable internet connection, you can eliminate a common cause of issues with adding contacts on LINE. If your connection is strong and you're still facing problems, move on to the next troubleshooting step.

6. Blocked User Check

If you've been blocked by the person you're trying to add, you won't be able to connect with them on LINE. This is a privacy feature designed to prevent unwanted contact. Unfortunately, LINE doesn't explicitly notify you if you've been blocked, so you'll need to look for clues.

  1. Check Past Conversations: If you've had previous conversations with the person, try sending them a message. If the message isn't delivered (no read receipt appears), it could indicate that you've been blocked.
  2. Try Calling: If you try to make a voice or video call to the person and the call doesn't go through, it's another potential sign that you've been blocked.
  3. Search for Their Profile: Try searching for the person's profile within LINE. If you can't find their profile, it's possible they've blocked you or deleted their account.

It's important to note that these are just indicators, and there could be other reasons why you can't contact someone on LINE. However, if you suspect you've been blocked, there's not much you can do to circumvent it. Respecting someone's decision to block you is crucial.

7. Clear LINE's Cache

Over time, LINE accumulates cache data, which can sometimes become corrupted and cause issues. Clearing LINE's cache can help resolve these problems and improve the app's performance, potentially fixing the "can't add each other" issue. This process removes temporary files and data stored by the app, without deleting your messages or contacts.

  1. Android:
    • Go to your device's "Settings" app.
    • Tap on "Apps" or "Application Manager."
    • Find and select "LINE" from the list of apps.
    • Tap on "Storage."
    • Tap on "Clear Cache."
  2. iOS:
    • Unfortunately, iOS doesn't allow you to clear the cache for individual apps directly. You'll need to offload the app (which preserves your data) or delete and reinstall the app (which will delete your data).
    • Offload App (Recommended): Go to "Settings" > "General" > "iPhone Storage" > "LINE" > "Offload App." This removes the app but keeps its data, so when you reinstall it, your messages and contacts will be restored.
    • Delete and Reinstall App (Data Loss): Go to your home screen, long-press the LINE app icon, tap "Remove App," and then tap "Delete App." Reinstall LINE from the App Store. This will delete your messages and other app data, so use this option as a last resort.

By clearing the cache, you're giving LINE a fresh start and potentially resolving any issues caused by corrupted data. If you're still facing problems after clearing the cache, move on to the next troubleshooting step.

8. Reinstall the LINE App

If none of the above steps have worked, reinstalling the LINE app is a more drastic but often effective solution. This process completely removes the app from your device and then reinstalls it, ensuring you have a clean and fresh installation. This can resolve issues caused by corrupted files, software glitches, or other underlying problems.

  1. Uninstall LINE:
    • Android: Go to your device's "Settings" app > "Apps" or "Application Manager" > "LINE" > "Uninstall."
    • iOS: On your home screen, long-press the LINE app icon, tap "Remove App," and then tap "Delete App."
  2. Restart Your Device: After uninstalling LINE, restart your device to ensure all traces of the app are removed.
  3. Reinstall LINE: Go to your device's app store (Google Play Store for Android or App Store for iOS) and search for LINE. Download and install the app.
  4. Log In: Open the LINE app and log in with your existing account credentials. Your contacts and chat history should be restored from LINE's servers (provided you have backups enabled).

Reinstalling the app provides a clean slate and can often resolve persistent issues that other troubleshooting steps couldn't fix. If you're still unable to add someone after reinstalling, it's possible the issue lies with the other person's settings or account.
