The Basics

What is 10DLC — and Why Does It Matter?

10DLC (10-Digit Long Code) is the US carrier framework requiring all businesses sending A2P (Application-to-Person) SMS from 10-digit numbers to register their brand and every campaign with The Campaign Registry (TCR).

Carriers use 10DLC registration to verify sender identity, prevent spam, and assign throughput limits. Unregistered traffic is filtered or outright blocked — which means your OTP codes, appointment reminders, and marketing campaigns simply don't arrive.

With Nuxsol, registration is handled end-to-end. You provide your business details and campaign description — we do the rest, from TCR submission to carrier attestation and throughput optimization.

How It Works

10DLC Registration in 5 Steps

Nuxsol manages the entire process. You submit your business information once — we handle TCR, carrier filing, and activation.

1
Brand Registration

Register your company with The Campaign Registry (TCR). Requires EIN, legal business name, website, and industry vertical. We pre-validate everything before submission to avoid rejections.

2
Use Case Selection

Choose the right campaign type: 2FA/OTP, marketing, customer notifications, account alerts, or mixed. Mismatched use cases cause carrier filtering — our team ensures the right fit.

3
Campaign Submission

We craft compliant campaign descriptions, sample messages and opt-in/out flows, then submit to TCR and every major carrier (AT&T, T-Mobile, Verizon) for vetting.

4
Number Assignment

Once the campaign is approved, we assign your 10DLC numbers and provision them on your account. Numbers are linked directly to the approved campaign — nothing provisional.

5
Live & Monitored

Your campaign goes live with full deliverability. We monitor throughput, carrier feedback, and any compliance updates — and notify you before anything requires action.

Questions

Frequently Asked Questions

Yes. Volume is irrelevant — any A2P SMS sent from a 10-digit long code in the US requires 10DLC registration, regardless of daily message count. Unregistered numbers are subject to carrier filtering at any volume. The cost of registration (typically $10–$25/month) is almost always lower than the cost of blocked messages.

Brand registration typically completes in 24–48 hours. Campaign vetting by carriers (especially AT&T's manual review) can add 1–3 business days. Nuxsol's average end-to-end time is 48 hours for standard use cases. Mixed or high-risk use cases may take longer due to carrier manual review requirements.

For brand registration: legal business name, EIN, business website, physical address, and industry vertical. For campaign registration: campaign type (use case), message description, sample messages (2–5 examples), and documentation of your opt-in process. Nuxsol provides templates for all required documents.

Yes. A single brand registration can support multiple campaigns — one per use case. For example, you can have separate registered campaigns for transactional 2FA, marketing messages, and customer care notifications. Each campaign gets its own throughput allocation and numbers.

Campaign rejections usually result from unclear use case descriptions, missing opt-in documentation, or sample messages that don't match the declared use case. Nuxsol's compliance team reviews the rejection, revises the submission, and resubmits at no additional charge. Our pre-validation process keeps our first-pass approval rate above 95%.

TCR charges a one-time brand registration fee (~$4) and a monthly campaign fee (~$10/month per campaign). Carrier pass-through fees (~$0.003 per SMS on AT&T) also apply. Nuxsol's managed service includes a small management fee on top of TCR pass-through costs — contact us for exact pricing based on your campaign count and volume.
