Enable 10DLC A2P SMS

Send and receive messages on local DID phone numbers with 10DLC messaging.

Enabling 10DLC on FreeClimb

To start utilizing 10DLC (10-digit long code) phone numbers on FreeClimb and ensure optimal message throughput per second (MPS), you'll need to let us know about your brand and the nature of the messages you'll be sending. Once you've completed the brand and campaign registration steps below, you'll be able to assign one or more FreeClimb phone numbers to your campaign and get started.


Before you begin

10DLC messaging requires a full FreeClimb account. Please ensure you've upgraded your account. If you're still using a trial account, you can upgrade your account on the Account > Upgrade section of your dashboard or by contacting FreeClimb support.

Step 1: Register your brand

Brand registration can be completed using our 10DLC Registration Form, which can also be reached from the 10DLC Messaging section in your FreeClimb dashboard. You'll be prompted to enter your contact information, as well as details about your company and/or brand, such as its name, organization type, and business vertical (e.g., financial services, healthcare, consumer products, education, etc.). Our team will then verify your submission with The Campaign Registry (TCR) and provide you with a brand ID and TCR Trust Score (1-100), which are required to register a 10DLC campaign.

To improve your initial TCR Trust Score, you may request additional vetting by contacting FreeClimb support. Vetting fees may vary.


What message throughput can I expect?

Prior to completing brand and campaign registration, your message throughput will be up to 50 messages per hour and up to 100 messages per day. Unregistered messaging traffic is also likely to be filtered by phone carriers, limiting your ability to deliver messages to your intended recipients.

Until your FreeClimb 10DLC-enabled phone numbers or Off-Net numbers are linked to a 10DLC campaign, they will be considered unregistered, restricting your ability to send test traffic. After linking a phone number to a registered 10DLC campaign, your message throughput can be adjusted based on your brand TCR Trust Score and your selected campaign type. Example MPS throughput limits are provided in the table below.

50 - 74120404040

(regardless of Trust Score)

Step 2: Register your campaign

Once you've received your 10DLC FreeClimb brand ID and MPS throughput, register your campaign using our 10DLC Registration Form. You'll be prompted to enter some account and contact information, as well as details about your campaign:

  • Campaign Description: A few sentences summarizing your campaign.
  • Use Case: Drop-down menu selection of your intended use for 10DLC messaging (e.g., two-factor authentication (2FA), customer care, marketing, security alerts, etc.).
  • Vertical: Drop-down menu selection of your business vertical (e.g., financial services, healthcare, consumer products, education, etc.).
  • Sample Message(s): One to three examples of messages you plan to deliver with 10DLC on FreeClimb.
  • Opt-in, Opt-out, and Help Messages: Message content that will be sent to recipients in the event that they opt-in, opt-out, or request help.

Once you submit your campaign registration information, our team will submit it to TCR. Each brand submission incurs a variable one-time fee, as well as ongoing monthly rates. When your campaign is qualified, you'll be able to conveniently review your brand and campaign information (i.e., brand name/ID, registration date, and brand status*) in your FreeClimb dashboard.


A Note on Brand Statuses

When registration is completed, TCR assigns brands a VERIFIED or UNVERIFIED status based on supplied information. If your brand shows an UNVERIFIED identity status, then your brand will not qualify to run 10DLC SMS campaigns on any MNO (Mobile Network Operator) network. Below is a complete list of applicable brand statuses:

  • UNVERIFIED: TCR is unable to verify or identify the existence of the brand. An UNVERIFIED brand is not permitted to run a 10DLC campaign.
  • VERIFIED: TCR is able to verify provided information and identify the existence of the organization. A VERIFIED brand is permitted to run standard 10DLC campaigns across all MNO networks.
  • VETTED_VERIFIED: A VETTED_VERIFIED brand may potentially gain access to higher throughput (message segments per second) and additional use-cases across some MNO networks.

Step 3: Link phone numbers

With brand and campaign registration completed, you are now ready to link your FreeClimb 10DLC-enabled phone numbers or Off-Net numbers (see below) from your dashboard, or by sending an email to FreeClimb Support. You can also purchase additional numbers. As a reminder, toll-free phone numbers are not eligible to be linked to 10DLC campaigns and therefore will not appear in the list of available numbers to be linked to your 10DLC campaign.


Off-Net numbers

To 10DLC-enable Off-Net numbers, or numbers not hosted on FreeClimb, you can download a Letter of Agency (LOA) for the requested numbers and email it to FreeClimb Support. Once the LOA is received, we will initiate the process for 10DLC-enablement and inform you when the requested number(s) will be available to manage in the FreeClimb dashboard. Please note that Off-Net 10DLC numbers will be enabled for 10DLC SMS traffic only. Voice traffic will not be ported to FreeClimb.


Please note

Please note that sending traffic which does not comply with the CTIA guidelines, drifts from your registered use case, includes prohibited content, or exceeds the approved limits at which you are allowed to send, may result in your messages being filtered, your use case registration being suspended, or your FreeClimb account being suspended. Prohibited content includes "S.H.A.F.T." use cases or content related to Sex, Hate, Alcohol, Firearms, Tobacco and Vape/E-cigs.
