How to move P2P long codes and short codes to Verizon 10DLC

Your guide to using the new Verizon commercial long code for SMS and MMS communications

OpenMarket – January 18, 2020

It’s been a long time coming, but the A2P 10DLC era is finally upon us.

Verizon is now accepting 10DLC traffic on its network. You can continue sending long-code traffic – using the same numbers as you always have – on the Verizon network. But it will be subject to filtering to remove the risk of spam, smashing and abusive content.

The Verizon shared short code policy hasn’t been announced. But Verizon and the other major US carriers are likely to limit their use because shared short codes are seen as a spam risk. Once all the major US carriers – Verizon, T-Mobile, Sprint and AT&T – have launched their 10DLC services, a lot of shared short-code traffic will need to be migrated.

(We talk about the various situations in which businesses might be allowed to use shared short codes later in this post.)

Verizon, short codes, and moving to 10DLC (ten digit long codes)

If your business has been relying on long codes (which were only ever designed for person-to-person use) or shared short codes, 10DLC might be your best option.

When all the US carriers will launch their 10DLC services is not yet clear. The demands on their businesses and networks caused by COVID-19 looks to have pushed timetables back for all of them. However, it would seem reasonable to expect that all of them will launch by the end of 2020.

What’s certain is that 10DLC will become the new standard in A2P (application to person) messaging for many businesses. But dedicated short codes will still be available as a premium service.

What are your US business messaging options in 2020?

In 2020, businesses that want to communicate with customers via SMS and MMS in the US will effectively have three options to choose from:

1 Dedicated short codes
The monthly costs are steeper than long codes, but dedicated short codes enjoy higher carrier support, and higher potential throughput – 1,000 messages a second and more – for time-sensitive communications to large audiences.

2 A2P 10DLC
Verizon 10DLC (and the upcoming 10DLC services  soon to be offered by carriers) have far lower monthly costs  than dedicated short codes. And they’re much faster and more simple to provision. (In fact, if you use OpenMarket’s automated, self-service 10DLC platform,  your number can be ready in seconds. ) 10DLC will have far higher messaging throughput than P2P long code traffic, and better reliability and stability.

If you have existing long code traffic, it can simply move over to the 10DLC service.

A key difference between 10DLC and shared short codes is that mobile operators won’t support delivery receipts on 10DLC.

3 Text-enabled toll-free (TETF) numbers
This is a service that allows businesses to “text enable” existing toll-free phone numbers, so they have one number customers can either text or call them on. These TETF numbers have a high throughput (though not quite as high as short codes) and are secure and approved for business use.

In summary, 10DLC and TETF are messaging options for businesses that want to start messaging quickly and easily without the higher cost sometimes associated with short codes.

But short codes will remain the preferred routes for brands that want to send time-sensitive communications to very large audiences.

10DLC vetting requirements

We expect at least some of the US carriers to put a vetting process in place in order to ensure its routes stay as spam free as possible. Verizon does not require businesses that use its 10DLC service to undergo a vetting process. But those that turn to 10DLC might need to submit themselves to vetting and scoring for spam risk if they want to get the desired messaging throughput from all the carriers.

An example of a use likely to be judged as low risk would be two-factor authorization (2FA). That’s because consumers have asked for this traffic, they respond to it, and it’s safe and necessary.

On the other end of the scale will be promotional marketing campaigns, as there’s a potential for these campaigns to be sent to consumers who may not have been opted into the campaign correctly.

Businesses that can demonstrate the quality of their traffic will enjoy optimum throughput and timely delivery of messages from all carriers.

The end of P2P long codes and shared short codes for A2P messaging

Mobile operators will use firewalls and other software techniques to rid their routes of traffic from unsanctioned long code and shared short codes that don’t meet their qualifying criteria.

We believe shared short codes legitimately used by parent companies for individual businesses (like a chain of restaurants) will be supported, but this would be at the discretion of each mobile operator.

In October 2018, AT&T listed specific use cases it will clear for shared short codes:

-Emergency notifications
-2FA / OTP
-Transit alerts
-Job postings (if the message sender is doing the hiring)

Remember, other carriers may have longer or shorter lists.

If you’re unsure about any of the above, OpenMarket can help. Let us know about the use cases you have running on your shared short codes and we can advise if they could be considered for exemption.

Your next steps

Look for a mobile messaging provider that makes the migration and sign-up process for 10DLC as simple as possible.

In summary, businesses should work with providers that allow them to easily:

– Look for and purchase 10DLC numbers
– Configure them for use
– View the status of campaigns and see which 10DLCs are assigned to them
– View a summary of all the owned 10DLC numbers and their status
