After your A2P brand and campaign are approved, each applicable phone number must be associated with the approved campaign before it can use the registered messaging route. Linking the number helps ensure compliant SMS and MMS delivery through a 10-digit local number. This process is also useful when you purchase an additional number or encounter SMS error 30034.

What Is Linking Phone Number to A2P Campaign?

A2P campaign linking associates a specific phone number with an approved A2P 10DLC campaign. This connection tells carriers which registered business and messaging use case apply to messages sent from that number.

A phone number may be available in GHL Customer Care without being linked to your approved campaign. When the association is complete, the number displays an A2P Verified label on the Phone Numbers page as shown in the screenshot below.

A2P 10DLC registration applies to business messaging through applicable US 10-digit local numbers. Toll-free phone numbers do not use A2P campaign linking and follow a separate verification process.

If a Sole Proprietor sub-account has two or more local numbers, SMS error 30034 may occur even when one number was previously approved. Check the registration type in Settings > Phone System > Trust Center before linking additional local numbers.

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.

Troubleshooting Error 30034

Error 30034 can occur when the sending number is not linked to a valid, approved A2P campaign. It can also occur when a Sole Proprietor registration has more than one local number, because Sole Proprietor registrations only support one local number per campaign.

Before escalating or re-registering the campaign, check the following:

  • Go to Settings > Phone System > Phone Numbers and locate the sending number. Confirm whether the number displays the green A2P Verified label. If the label is missing, use the steps above to link the number to the correct approved A2P campaign.
  • Go to Settings > Phone System > Trust Center > Brands and Campaigns. Confirm whether the account is registered as Standard or Sole Proprietor. If the account is Sole Proprietor, confirm that only one local number is being used. If there is more than one local number in a Sole Proprietor account, reduce the setup to one local number or review whether the business should complete Standard registration instead.

Frequently Asked Questions

Q: Does campaign approval automatically link every phone number?
No. Check each applicable number on the Phone Numbers page. A linked number displays the green A2P Verified label.

Q: Can I link an additional phone number after my campaign is approved?
Yes, when the registration type supports additional local numbers. Sole Proprietor registrations are limited to 1 campaign and 1 phone number per campaign.

Q: How can I tell whether a number is already linked?
Look for the green A2P Verified label beneath the number in Settings > Phone System > Phone Numbers.

Q: How can I tell whether the account uses Standard or Sole Proprietor A2P registration?
Open Settings > Phone System > Trust Center > Brands and Campaigns and review the registered brand type.

Q: Why is the approved phone number also getting error 30034?
Error 30034 can occur when the sending number is not linked to a valid approved A2P campaign. First, check whether the number displays A2P Verified in Settings > Phone System > Phone Numbers and link it to the correct campaign if needed. If the account uses Sole Proprietor registration, error 30034 can also occur when the account has multiple local numbers, because Sole Proprietor registrations only support one local number per campaign.

Q: Why does my number not display A2P Verified after purchase?
The number may not yet be associated with an approved campaign. Use the three-dot menu to check whether a campaign can be selected. Before linking, confirm whether the account uses Standard or Sole Proprietor registration.

Q: Can a toll-free number be linked to an A2P campaign?
No. Toll-free numbers use a separate verification process and do not use A2P 10DLC campaign linking.
