1. Add account privacy settings restrictions
Problem description:
If you receive a "Cannot add friend" message when trying to add a friend, it's likely that the other person's privacy settings restrict how you can add them. For example:
l The other party has disabled the "add friends by ID" permission
l The other party has turned off the "Add friends by phone number" permission
l The other party has set it to "Reject strangers adding"
Solution:
l Use QR code to add users instead . Ask the other party to show the QR code and scan it to add them directly.
l Use mutual addition in the group : first invite both parties to join the group, and then add friends in the group.
l Guide the other party to enable the corresponding permissions : Settings → Friends → "Allow me to be added by ID/phone number".
2. Your account is restricted or blocked
Problem description:
If you frequently add strangers or use unofficial channels to add friends in batches, and the LINE system identifies this as abnormal behavior, it may trigger system restrictions and prevent you from adding friends in the short term.
Solution:
l Suspend operations for more than 24 hours and wait for the system to lift restrictions.
l Do not add multiple unfamiliar users frequently in a short period of time.
l Check whether the account has any other abnormal prompts (such as being locked, function suspended, etc.).
3. The other party has blocked you or deleted you
Problem description:
If the other party has blacklisted you , or has added you and then deleted you , the next attempt to add you will fail and a "Unable to add friend" prompt will appear.
Solution:
l Try to communicate with the other party through other contact methods and ask them to be removed from the blacklist.
l Create a new account or reconnect using a different method (such as a shared group).
4. Wrong addition method or invalid information used
Problem description:
If you enter the wrong ID, the phone number format is incorrect, or the image is unclear or expired when scanning the QR code, the system may not be able to recognize it and display "Unable to add friend".
Solution:
l Verify that the ID is spelled correctly (it is case-sensitive).
l The phone number must include the country code, for example, Taiwan is "+886".
l If using a QR code, please ensure that the image is complete and clear.
5. The other party's account is abnormal or frozen
Problem description:
If the other party's account has been blocked or restricted by LINE due to violations or long-term inactivity, a prompt may appear saying "Cannot add" is unavailable. This is more common in cross-border social media traffic generation.
Solution:
l Change the contact and find their backup account.
l If it is a customer account, it is recommended to retain backup contact information through multiple platforms (such as Telegram, WhatsApp).
l Pay attention to whether the account is registered using a virtual number, as such accounts are more likely to be frozen.
Practical reminder: Avoid the following "accidental addition" operations
l Do not use third-party plug-ins or automatic friend-adding tools . The LINE system strictly monitors such behavior.
l When adding friends in batches, you should do it in different time periods and batches to avoid too many operations in a short period of time.
l Do not frequently add strangers to public groups , as this will be identified as marketing behavior by the system.
How to improve the success rate of adding friends? Operational suggestions are as follows:
1. Provides multiple ways to add : ID, phone number, and QR code are displayed simultaneously to improve adaptability.
2. Clearly inform the other party of the addition steps : Especially for non-technical users, the addition process should be clearly visible.
3. Communicate privacy settings guidance in advance : Include instructions on how to turn on "Allow me to be added" in the guidance copy.
4. Combined with landing page guidance : Add operational instructions on "how to add friends" in the promotional link to reduce user failure rate.
