Error 30034: Link a Phone Number to Your Approved A2P Campaign
What this error means
Error 30034 means the US local (10-digit) number you're sending from isn't linked to an approved A2P 10DLC campaign. Carriers block or filter messages from unregistered numbers.
> Before you start: your A2P brand and campaign must already be approved. See *What is A2P 10DLC?* to register them.
Why linking matters
A number can exist in your sub-account without being linked to your campaign. Linking tells carriers which registered business and use case apply to messages from that number. It's also needed when you buy a new number or port one in after your campaign was approved.
How to link a number
- Go to Settings → Phone System.
- Open the A2P registration section and find your approved campaign.
- Choose the option to add or link phone numbers.
- Select the numbers you want to use for texting.
- Save. Allow up to 24 hours for carriers to finish provisioning.
After linking
- Check the number's A2P status tag on the Phone Numbers list.
- Send one test message after provisioning completes.
- Link each new number you add before you start texting from it.
