Before you begin

Make sure you have read the guides to register your 10DLC brands and campaigns before hand. Once you have registered your campaign, and that campaign has been approved by both Vonage and our partners, you can start linking numbers in order to send traffic for that campaign.

Numbers overview

Requirements

Please make sure you understand the numbers requirements for 10DLC campaigns:

• Numbers can only be linked to a single 10DLC campaign at a time
• Numbers can be added to a Vonage number pool, but if linking more than one U.S. or Canadian numbers to a number pool, all the numbers must be linked to the same 10DLC campaign
• Traffic can only be sent from a number once the linking request has been approved

Features

HIPAA

Vonage can offer HIPAA numbers, if you have enabled the HIPAA feature on your Vonage account, you will be prompted to enable the HIPAA capability when linking your numbers to your campaign. This will ensure that the SMS capability for this number is HIPAA compliant. Reach out to your account manager to enable HIPAA on your account.

SMS and MMS capabilities

Every number linked to a 10DLC campaign will be automatically enabled for both SMS and MMS messages. Every 10DLC campaign is MMS capable, with different throughput rates for some carriers.

Purchasing numbers

If you do not currently own a U.S. or Canadian number, you can purchase a new number via our dashboard. If you already own numbers, you can go straight into a 10DLC campaign, under the numbers tab, to link the numbers to your campaign. When purchasing your +1 phone number, make sure that the number has the SMS & MMS capabilities.

Porting numbers

If you wish to port existing numbers into Vonage, please check this article.

Linking time

Linking numbers to a campaign needs to be replicated and approved by each carrier to be fully provisioned. Note that linking a number typically takes under 5 minutes, but we have seen instances of linking requests taking several days to be completed. We recommend you to link your numbers a few days before you need to start sending traffic, to avoid disruption if the linking time was increased. We also recommend that you link large amounts of numbers in smaller batches to reduce the risk of increasing the linking time across the industry.

What happens next?

Rejected numbers

If the number goes to status rejected after requesting to link it to a campaign (like in the image above); it can be for multiple reasons, including:

• The campaign has reached its limit of approved numbers linked (49 by default)
• The number linking request timed out

Resolution:

• Make sure that you have not linked too many numbers to your campaign
• Try to unlink the number, wait 15 minutes, then link the number again
• Avoid unlinking numbers while the request is still pending
• If the linking failed after 36 hours, wait 15 minutes and try linking the number again

If those steps did not work or if you receive any other error message, submit a support request.

Additional Information

Number pools

If you need to link more than 49 numbers to a single 10DLC campaign, you will need to enable the number pool feature on that campaign. This process is outlined in this article.

Notes:

• Carriers prefer to avoid pooling numbers on 10DLC campaigns, so each request must be reviewed and approved before the feature can be enabled.
  The timeframe to process those requests is one to two weeks.
• On the 10DLC network, throughput is set at the brand or at the campaign level for most use-cases. Having more numbers will not increase the amount of messages that you can send.
• Enabling the number pool feature will in most cases allow you to link a maximum of 5000 numbers to the campaign.
