Possible Causes


Error Description: You attempted to send a message to a U.S. number from a 10DLC number that is not associated with a registered A2P campaign.


You are sending messages to the US using a US 10DLC number that is not associated with an approved A2P 10DLC Campaign.

Possible Solutions


  • Associate your US 10DLC number with a registered A2P Campaign by adding it to the corresponding Messaging Service via the leadconnector.

  • Alternatively, you can also use a different number that is already associated with an approved A2P Campaign to send messages in the US.


IMPORTANT: In some cases, resolving this error may require business verification. If we (or the provider) requests it, please have these ready:

EIN letter (CP-575 or 147C) and send it to us and we’ll guide the next steps.


Properly linking the number completes the association between the sending number and its approved campaign. Repeat these steps for each additional applicable number that needs to use the campaign.


  1. Go to Settings > Phone System > Phone Numbers.


  2. Locate the phone number that you would like to link to an A2P campaign and select the three-dot menu on the right side of that number.

    If this number is not yet added to an A2P campaign, it will not have the green A2P Verified badge.


  3. Click on Select A2P campaign to Link.


  4. Select the campaign that should be associated with the number.


  5. Return to the Phone Numbers list and confirm that the green A2P Verified label appears beneath the number.
