Introduction
When running bulk SMS campaigns in Kenya, your sender name is often the first impression your customers get. Instead of receiving messages from random numbers, they see a branded Sender ID like “Safaricom,” “CoopBank,” or “Jumia.”
A registered Sender ID not only builds trust and brand recognition, but it also ensures compliance with Kenyan regulations and prevents misuse of your brand.
With SMSLeopard, businesses can easily register Sender IDs and follow best practices that keep their communication professional, secure, and effective.
What is a Sender ID?
A Sender ID is the name or number that appears as the sender when a customer receives your SMS.
Alphanumeric Sender IDs → e.g., “MyBusiness”
Numeric Sender IDs / Short Codes → e.g., “22345”
In Kenya, most businesses prefer alphanumeric Sender IDs because they showcase the brand name, are easy to recognize, and prevent fraud.
Why Register Your Sender ID?
Sender ID registration is not just a formality—it’s a critical step for:
Brand protection → Prevent fraudsters from sending messages pretending to be your business.
Customer trust → Customers are more likely to open and engage with branded messages.
Regulatory compliance → Mobile operators in Kenya (Safaricom, Airtel, Telkom) require approved IDs.
Message deliverability → Unregistered IDs risk being blocked or flagged as spam.
Sender ID Registration Process in Kenya (via SMSLeopard)
Create an SMSLeopard Account – Log into your dashboard.
Apply for a Sender ID – Provide your preferred Sender Name (e.g., “MyBizKE”).
Submit Documentation – Depending on the operator, you may need:
Business registration certificate or license
Letter of authorization on company letterhead
Sample messages for intended use
Operator Approval – Safaricom, Airtel, and Telkom review and approve the Sender ID.
Activation – Once approved, SMSLeopard configures your account, and your messages will display the branded Sender ID.
Tip: Approval timelines vary between operators but typically range between 3–7 working days.
Best Practices for Sender ID Management
To maximize the impact of your branded Sender ID:
1. Choose a Clear and Recognizable Name
Use your official business name or a close abbreviation.
Avoid generic terms like “Info” or “Alert”.
2. Stay Consistent
Use the same Sender ID across all campaigns.
Consistency builds brand recall and avoids customer confusion.
3. Keep it Short and Professional
Maximum characters: 11 (alphanumeric).
Example: “CoopBank” (✔) vs “BestDealsOnlineKE123” (✘).
4. Avoid Misleading Names
Do not impersonate other brands.
Avoid sensitive terms like “Bank,” “Government,” unless officially registered.
5. Monitor Usage and Reports
Regularly check SMSLeopard’s delivery reports to ensure messages with your Sender ID are reaching customers.
Handling Multiple Sender IDs
Some businesses may need different Sender IDs for different purposes:
Marketing campaigns → “MyBizPromo”
Transactional alerts → “MyBizAlert”
Customer support → “MyBizHelp”
On SMSLeopard, you can manage and switch between multiple approved Sender IDs directly from your dashboard.
