The Challenges 10DLC Messaging Solves & How To Comply

Last Updated September 29, 2022

Because of the increasing popularity of texting, US telecom carriers have brought in a few standards that help you send high-volumes of text messages using 10DLC (10-digit long code) numbers. 

Adopting these 10DLC numbers solves multiple problems caused by shared short code and improves deliverability. 

Reach out to us to get 10DLC numbers for your organization.

Let’s start with understanding what 10DLC is.

What is 10DLC?

A 10-digit long code (10DLC) number is issued by US telecom vendors and is the new standard for A2P SMS used by organizations.

Now, your organization may already use local phone numbers to communicate with your contacts through text messaging. 10DLC numbers are similar but are issued only after vetting. 

What are the benefits of 10DLC?

Here are the four primary benefits of using a 10DLC number.

Higher message throughput

A 10DLC number allows you to send up to 180 messages per second, which can be further increased based on your use case. Whereas with a normal long code, you could send 1 message per second. 

Better deliverability

As 10DLC numbers are already approved by the carriers, your messages are more likely to reach your contacts without getting filtered out unlike regular long code numbers. 

Increased ROI

You can set a local presence with your 10DLC number and so, you increase the chances of getting a response. This also helps you reduce the costs involved in following up with your contacts. 

Lower costs

Organizations can turn their existing landline numbers into 10DLC ones. This eliminates the cost required for getting a new number. Also, 10DLC numbers have lower monthly costs compared to dedicated short codes. This makes it a cost-efficient solution for your texting campaigns. 

Who should comply with 10DLC regulations?

If you send SMS and MMS via local 10-digit long codes in the US, you need to register your brand and use case(s) with The Campaign Registry(TCR). TCR will then register you with the US carriers if you are sending more than 3000 messages per day or from more than 5 phone numbers.

CallHub can help you register and get 10DLC number(s), but more on that later.

Every organization regardless of their industry must register their brand and campaigns with TCR to avoid heavy filtration by the carriers. 

Why should you use 10DLC SMS messaging?

When you register your brand with TCR, you go through a vetting process where you’re given a ‘trust score’ which determines your message throughput(up to 180 messages per second).

Since October 1st 2021, most carriers don’t support message traffic from unregistered local numbers.

This means messages will not get through to your audience on that carrier. If you continue to use unregistered local numbers for texting, you will experience disruption of service due to heavy filtrations and blockages by the US carriers. 

However, 10DLC has no impact on Voice Broadcasting or Robocall campaigns. 

Here are some best practices for managing message filtering and opt-outs

How do you comply with 10DLC?

The first step is to register your organization with TCR (The Campaign Registry). There are 2 steps of registering:

  1. Brand registration, to identify your organization.
  2. Campaign registration, to identify the type of messages you’d be sending. For example, if it is an alert, a promotion or a political text etc.

The process starts with registering your organization with TCR and then moving onto getting a 10DLC number. Although they both are a part of the same process, they are independent vetting processes.

But wait, we are doing all this on your behalf.

The difference between the two is that special use cases primarily include charity/501(c)(3) nonprofit, emergency services, and political use cases. Business, education, and public services are listed under the standard category.

What are some 10DLC messaging alternatives?

There are two more types involved in A2P messaging apart from 10DLC. However, please note that these are not replacements for 10DLC. Each of these options is ideal for specific use cases. 

Toll-free numbers

You can use a toll-free number for both voice calls and text messages. You can also brand them to increase your brand familiarity. Toll-free numbers are two-way, and so your contacts can respond to your texts. 

When are they ideal?

  • Sales and support
  • Surveys and feedback
  • Reminders and updates

Short codes

A short code is a 5-6 digit number used to send high-volume bulk text messages to contacts. There are two types of short codes: Dedicated and shared. A dedicated short code is owned exclusively by an organization whereas a shared short code is shared between many. 

When are they ideal?

  • Two-factor authentication
  • Alerts
  • Time-sensitive promotions

What’s happening to shared short codes in the US?

Carriers are demanding to move the traffic from shared short codes to 10DLC and dedicated short codes. 

Shared short codes impose a high risk of spamming. Because the short code is shared by multiple organizations, it becomes difficult to put a finger on the bad actor. With a dedicated short code and a 10DLC number, carriers can have visibility on which organizations are sending what messages, and thereby protect the public from being spammed.

You can expect this to get truncated in phases.

We understand that the process involved with these sudden changes can feel daunting and you may have more questions surrounding 10DLC. This blog addressed some top queries to acquaint you with the new norms and rules. But if you have other queries around trust score, short codes, etc., we have covered them too.
