In Zoho Campaigns, we support one kind of sender address format when you use our in-built SMS gateway,
- Long code
We will support short codes and alphanumeric codes shortly when we support a few more countries. Let's explore this sender address format in detail.
Long code
Long codes or 10DLC (10 Digit Long Code) are the normal 10-digit phone numbers that can be used to send bulk SMS messages and make voice calls. It is somewhat similar to the phone numbers we have for personal use, except these 10DLCs are used for business purposes.
It is also referred to as A2P (Application to Person) 10DLC, as business messages are sent to prospective customers via an application. Using long code is ideal for localized systems, within a branch or store, segmented customer base.
Long codes can be used to send:
- Chats (text and voice messages)
- Event based interaction
- Service update
- Reminder for appointments
