You may have seen a lot of information circulating in the US about 10-Digit Long Codes over the last few months. Long Numbers have been around for a long time and are nothing new in the messaging industry, so why are they being talked about so much now? 10DLC is the acronym assigned to the carrier sanctioned long code traffic.
First, 10DLCs are set to become more important in the US market than anywhere else, as the use of shared Short Codes across multiple clients and binds for A2P (Application to Person) traffic has caused many compliance issues that resulted in blocking/suspension of all clients on the code.
With 10DLCs are due to kick off in 2019, we held a webinar in October 2019 taking a deeper dive into them. Click here to access the recording.
Please note that the majority of Short Codes in use today are dedicated Short Codes – these will not be impacted.
The main difference between these two sender types is how they’re intended to be used. Long Codes were designed to support P2P (Person to Person) messages – with a relatively low throughput of messages. Short Codes (SC) were designed to support A2P (Application to Person) bulk, higher throughput messaging – this a pre-approved route, which eliminates filtering.
Over time, demand for and use of messaging channels has changed. A2P messages are being sent on Long Codes, and some Short Code based campaigns support P2P like experiences with the application only hosting the consent and communication experience. The carriers have stepped in to get better control of the traffic on their networks in effort to increase security and deliverability.
Truth is, shared Short Codes have earned a bit of a reputation over the years, here’s why:
Carriers want to weed out these bad actors and add a layer of accountability that shared Short Codes are unable to provide. With 10DLCs, each business would have their own dedicated number(s) – so accountability issues disappear. Each business would be vetted.
A2P 10DLC will enrich engagements, which we love to do!
Verizon will be first to screen and possibly block A2P traffic running on Long Codes. Other carriers are expected to follow soon after. Get in touch with your Account Manager and Sinch’s compliance experts to discuss what the best solution might be for your existing shared Short Code.
