Title: 10DLC registration: A step-by-step guide for A2P messaging URL: https://www.infobip.com/blog/10dlc-registration For B2B platforms that help businesses send SMS and MMS in the US, 10DLC registration is part of the job. Your customers need approved brand and 10DLC campaign registrations before they can send at scale, and your platform needs a process that keeps onboarding fast without creating compliance headaches. This guide shows you how to manage 10DLC registration and campaign approvals step by step. It covers what needs to be registered, what carriers look for, and how Infobip helps you launch faster with less manual work. ## Why does 10DLC registration matter? Your customers are expecting to be able to send high-volume messaging over SMS or MMS, and so registering a 10DLC number needs to be done quickly and efficiently. But carriers require registration, so they can verify who is sending traffic, what the messages are for, and whether the campaign follows all the right compliance rules. This affects how quickly customers can go live, how much trust carriers place in their traffic, and how reliably messages are delivered. A clean registration process with guidance from a team of compliance experts helps reduce rejection risk, protects sender reputation, and keeps onboarding moving. It also gives your customers a better experience. Instead of dealing with delays or unclear approval steps, they get a guided path to approved messaging, provided by your platform. That makes messaging easier to scale, easier to support, and easier to turn into a repeatable platform workflow. ## What you need to register a 10DLC campaign To register 10DLC campaigns successfully, platforms need to collect the right business and campaign details up front. Carriers use this information to verify the sender, review the use case, and approve traffic that matches the registered campaign. At a minimum, you should prepare: 1. **Brand information:** legal company name, business type, tax ID, and address 1. **Campaign purpose:** a clear description of what the messages are for 1. **Use cases:** the types of messages the customer will send 1. **Message examples:** sample SMS or MMS content that matches the campaign 1. **Opt-in process:** how recipients consent to receive messages 1. **Support details:** contact information and escalation path 1. **Terms and conditions:** if required for the use case For platforms, the goal is to make this information easy to capture during onboarding so customers do not hit delays later in the approval process. The cleaner the submission, the faster the campaign can move through review and brands can start sending their messages. ## Step-by-step campaign registration flow for 10DLC numbers Each registration needs the business details carriers use to validate the sender, plus the campaign information that explains what traffic will be sent, how users opt in, and what support recipients can expect. Platforms also need a way to keep submissions organized as campaigns move through review, approval, and ongoing management. ### Assigning or registering a dedicated 10DLC number An obvious first step in the registration process is to obtain a 10DLC number. You can do this through the Numbers app after you sign up with Infobip or over Numbers API. Already have a 10-digit long code number? No problem, we can help you register an existing number as well. ### Register the brand The brand must be included in The Campaign Registry (TCR) by providing the business and legal information. Mobile carriers in the US use this registry to validate brands, which means if a brand is not verified with TCR then they cannot send 10DLC messages over these carriers. What is The Campaign Registry? The Campaign Registry (TCR) is a central database for 10DLC and A2P campaign registration. It helps keep a clean messaging ecosystem where carriers can ensure the brands sending large amounts of messages over their networks are legitimate and not spamming end-users. ### Registering the campaign Network operators in the US require registration of every campaign launched over a 10DLC number. They want to ensure the messages are relevant and legitimate and not harmful spam. Each campaign registration requires: 1. The brand the campaign is associated with 1. Basic information like the name of the campaign, a summary, and use cases 1. How you plan on collecting opt-ins 1. Examples of messages 1. Support contact information and terms and conditions ### Campaign review The Infobip Compliance Team will review and determine if the campaign meets the compliance standards. AI-powered pre-checks will also help you identify any red flags before submission to help avoid any rejections. In the event a campaign is rejected by the Infobip Compliance Team you will be provided with a reason and chance to fix it. If all checks out, the campaign will be registered with TCR and will be ready to use. ### Launching once the campaign is approved Once your campaign is reviewed and approved by the Infobip Compliance Team, it will be registered with network operators in the US, and you can start sending traffic with your 10DLC number. Depending on the use case, if additional approval is needed the carrier will review it before it goes live. You can complete the whole process through our platform. If you aren’t satisfied with the message volumes received from mobile carriers, you can request a third-party vetting (however, getting a higher throughput is not guaranteed). The real value for platforms is in making this process consistent. The easier it is to register, review, and manage campaigns at scale, the faster customers can go live without creating compliance friction. It takes an average of 4 days to review and officially submit a campaign to TCR. Need faster registration? No problem, we can speed up your registration for 10DLC numbers and campaigns with our Swift Launch service. We’ll take care of all the heavy lifting and get you sending messages in no time.

These issues can slow down onboarding and create extra work for both your team and your customers. Common rejection reasons include: 1. **Missing or incorrect information:** Business details, tax information, or campaign fields are incomplete or cannot be verified. 1. **Unclear use case:** The campaign purpose is too vague or does not match the messages being submitted. 1. **Weak opt-in details:** Carriers need to see how recipients agreed to receive messages. 1. **Non-compliant content:** The content looks spammy, misleading, or outside approved guidelines. 1. **Poor sender reputation:** High opt-out rates, spam complaints, or previous compliance issues can affect approval. 1. **Missing support details:** Carriers expect clear contact information and terms where required. The goal is to catch these issues before submission, because each rejection delays activation, and every day a campaign sits in review is a day your customer cannot send their first message or launch the campaigns they onboarded for. ## How Infobip ensures faster and smoother registration and launches Infobip helps B2B platforms launch and manage 10DLC campaigns without turning registration into a manual bottleneck.
