[SMS Sendout](https://help.datatalks.se/email-mobile-messaging?hsLang=en#sms-sendout) # SMS Sender Registration ## Register, manage, and configure sender IDs to ensure successful and compliant SMS delivery #### Overview SMS sender registration is an essential step in setting up SMS communication through the CDP. Whether you're sending one-time ticket reminders, promotional offers, or automated campaign flows, having a verified and recognizable sender ID ensures delivery, compliance, and supporter trust. The CDP supports both **numeric** and **alphanumeric** sender IDs. You can register **multiple senders** within your account and assign different sender profiles to different use cases—such as separating transactional messaging from marketing or using different IDs for different departments or regions. ![Screenshot 2025-05-31 at 20.47.58](https://help.datatalks.se/hs-fs/hubfs/Screenshot%202025-05-31%20at%2020.47.58.jpg?width=670&height=166&name=Screenshot%202025-05-31%20at%2020.47.58.jpg) --- #### Sender Types ### 1. **Alphanumeric Senders** - Alphanumeric sender IDs are custom names made up of letters and numbers (e.g. *YourClubFC*). - These are often used for **branding purposes**, as the sender name appears clearly to the supporter. - Note: Alphanumeric senders **cannot receive replies**—they are **one-way only**. - Note: Alphanumeric senders can be maximum 11 character long Alphanumeric senders can be registered directly in the CDP under [Admin / SMS Sendout.](https://app.datatalks.se/admin/smssendout) --- ### 2. **Numeric Senders (Virtual Numbers)** - Numeric sender IDs use standard phone numbers (e.g. *+46701234567*). - These allow for **two-way SMS**, meaning supporters can reply to your messages and those can be accessed in the CDP. - Ideal for **interactive campaigns**, customer support, or opt-out flows. If you do not have a numeric sender already, **Data Talks can assist you in purchasing and registering virtual numbers**, tailored to the country and use case you're targeting. When configuring a Numeric Sender, you need to **get in contact with your Customer Success Manager.** --- #### Managing Multiple Senders You can register and manage multiple senders within your CDP account. This enables you to: - Separate marketing from service communications - Use language- or region-specific sender IDs - Customize the experience per audience segment When sending SMS messages from the campaign builder, you'll be able to select the appropriate sender for each message or flow. --- #### Sender Registration Process 1. **Decide on sender type(s):** - Alphanumeric for branding - Numeric for two-way communication 2. **Register Sender in CDP and/or Contact your Customer Success Manager:** - For registering alphanumeric senders, submit the maximum 11 character sender on the [SMS Sendout Admin page](https://app.datatalks.se/admin/smssendout). - For numeric senders, Data Talks will guide you through the purchase and provisioning of a virtual number. 3. **Provisioning & Compliance:** - In some countries, sender registration requires regulatory approval which may take up to 2-3 weeks (e.g.: US, UK, Australia). - Data Talks will handle this process and may require additional business information to submit the registration form. Your Customer Success Manager will notify you when the sender is approved. 4. **Assign Senders in Campaign Builder:** - Once registered, your sender IDs will appear in the dropdown menu inside the [SMS message builder](https://app.datatalks.se/smssendout). ![Screenshot 2025-05-31 at 20.56.41](https://help.datatalks.se/hs-fs/hubfs/Screenshot%202025-05-31%20at%2020.56.41.jpg?width=670&height=256&name=Screenshot%202025-05-31%20at%2020.56.41.jpg) --- #### Best Practices - Use clear sender names for transparency and trust. - Reserve numeric senders for cases where replies are expected or necessary. - Clearly distinguish marketing from transactional messages by using different sender IDs. - Always comply with local SMS regulations and opt-out requirements. --- #### Need Help?
