"This number is registered to an existing WhatsApp account"
Seeing an error such as this one indicates that this phone number has been used with another WhatsApp Business API provider in the past. If this is the case, to resolve this, you should follow the onboarding flow for “migrating an existing WhatsApp phone number from my current provider”, being sure to exit the WhatsApp embedded onboarding process after Step 2.
If this phone number has not been used with another WhatsApp Business API provider, this may indicate that the phone number has been used in an Android, iPhone, or Business application version of WhatsApp. You should follow steps 3 to 7 under the Learn more link of the error to disconnect the number from that WhatsApp account, then you should be able to retry our onboarding process successfully. Chat history will be lost on disconnection here so be sure to change it beforehand.
If neither of these options are the case for you then contact us and we can try manually connecting WhatsApp for you if you share with us your WhatsApp account ID and phone number.

You can check for this code in the console of your browser while going through the sign up process. If this error was during the phone number migration set up path, it could be that the migration has successfully occurred. You may instead be able to follow the “I’m integrating WhatsApp for the first time” set up path instead, selecting the new WhatsApp accounts that were created during the migration set up.
If this still fails, we can try manually connecting WhatsApp.

Check if number is fully verified by Meta, it has to be before you can connect it to Intercom so knowing that its successfully connected is important here. The number might already be in use with the WhatsApp Business app. In that case, you need to delete it from your app. If both of these checks fail then contact us and we'll try manually connect the number. Send us a screenshot of the verified number from WhatsApp Business Manager and provide the phone number and WhatsApp Business Account ID (WABA ID).

Troubleshooting WhatsApp message template issues
Troubleshooting WhatsApp message template issues
Templates Not Appearing in Intercom
Templates must belong to the "Utility" or "Authentication" categories. Templates in the "Marketing" category are not supported.
Ensure the template includes only plain text or quick reply buttons. Templates with media or unsupported variables may not sync.
Confirm that the template is fully approved in Meta and its language matches the language settings in Intercom. Refresh Intercom to sync approved templates.
Variable Formatting in WhatsApp Templates
Intercom requires templates to use numerical placeholders (e.g.,
##{{1}}) rather than descriptive ones like##{{sf_full_name}}. Example: Hi##{{1}}, your order##{{2}}has been shipped.If your templates using variables like
##{{sf_full_name}}fail, edit your template in Meta to replace descriptive placeholders with numerical ones and map these in Intercom.This ensures compatibility between WhatsApp and Intercom by mapping variables directly to Intercom attributes.
Preventing Reclassification of Templates as "Marketing"
Avoid promotional language; focus on transactional or support-related content.
Explain the intent (e.g., support or post-purchase confirmation) when submitting the template.
Avoid using media or excessive personalization.
