A shortcode is a 5-6 digit number used to send and receive text messages. There are two types of shortcodes: shared and dedicated. While you can send text message marketing with both shortcodes, shared shortcodes present some risks.
They are identified by specific keywords of the business’ choice such as CLIMATE for an environmental organization and SURVEY for a research firm, JOIN for a political campaign. However, all these keywords use the same shortcode that is 33339.
The biggest threat with shared shortcodes is bad actors go against messaging best practices and exploit the network, and the carrier has to suspend the services for the entire shortcode. Furthermore, it prevents good actors from engaging with their customers.
CallHub customers currently using shared shortcodes can now choose to move to one of three alternative options:
A2P (10 DLC) - 10-digit long numbers are used to text large groups at much higher speeds from local numbers, much like shortcodes, giving your campaign that local touch. However, A2P messaging (using 10DLC numbers) cannot provide handset delivery receipts, meaning your message delivery is better than toll-free or shortcode. You can get more details on 10DLC here.
CallHub Support will be happy to help you with the 10DLC registration process.
Toll-free numbers - Toll-free long codes numbers are classified as application-to-person (A2P) just like 10DLC, which allows messages to be sent at a higher message-per-second (MPS) rate. There is currently no vetting process. TFNs are generally used more for informational purposes but support 2-way messaging. However, you will be able to get delivery receipts.
Dedicated Shortcodes - A dedicated short code is an SMS shortcode that’s used and paid for exclusively by one organization. A few benefits or differentiators over the shared shortcodes: brand recognition, scalability, SMS keyword exclusivity, increased messaging throughputs, or expanded functionality.
