How to Create a USSD Code for Your Business in Kenya

Spread the love

In the age of mobile apps and digital wallets, it’s easy to overlook Unstructured Supplementary Service Data (USSD) — but that would be a costly mistake, especially in Africa. As of 2025, over 82% of mobile transactions in Kenya are still powered by USSD, making it the undisputed backbone of mobile engagement for banks, SACCOs, logistics companies, government agencies, and even local retailers.

Why? Because USSD works on any phone, without internet, and is available to virtually every mobile subscriber. Whether you’re collecting payments, delivering information, or providing customer self-service, a USSD code gives your business a direct, always-on mobile channel that reaches customers instantly.

This blog by Mobulk Africa walks you through a factual, step-by-step guide on how to create a USSD code for your business — from concept to launch — specifically within the Kenyan mobile and regulatory landscape.

What Is a USSD Code?

USSD (Unstructured Supplementary Service Data) is a session-based communication protocol used by GSM cellular phones. It allows users to interact with a service through a simple short code like *123#, without needing a smartphone or internet connection.

In Kenya, it’s commonly used for:

Mobile banking (e.g. *247# for Co-op Bank)
Airtime top-ups and utility payments
SACCO account management
Insurance claims
Retail loyalty programs
Government services (e.g. NHIF, eCitizen)

Types of USSD Codes in Kenya

Before you build your code, understand the two main types:

1. Dedicated USSD Code

Assigned exclusively to your business (e.g., *123#)
More expensive but offers full control
Ideal for banks, telcos, insurance, and government agencies

2. Shared USSD Code

Multiple businesses use the same short code, differentiated by a keyword (e.g., *234*9#)
Lower cost and faster setup
Suitable for SMEs, startups, and NGOs

Step-by-Step Guide to Creating a USSD Code for Your Business

Step 1: Define the Purpose of Your USSD Service

You can’t build a USSD code until you’re crystal clear on what it will do. Ask:

Are you providing balance checks or customer self-service?
Do you want users to apply for loans, pay for goods, or register for events?
Should the USSD be transactional (e.g., M-PESA integration) or informational (e.g., FAQs, updates)?

Example Use Cases:

A microfinance SACCO offering loan balance checks
A pharmacy chain offering prescription refills
A bus company offering seat bookings

Step 2: Choose Between a Dedicated or Shared Code

Cost comparison (Kenya, 2025 estimates):

Dedicated USSD Code: KES 90,000–150,000 setup + monthly fees (varies by telco)
Shared USSD Code: KES 10,000–20,000 setup + low monthly maintenance

For most small businesses, a shared code via Mobulk Africa is the smarter choice to start.

Step 3: Design Your USSD Menu Flow

This is where things get real.

USSD is menu-driven, and you only have 182 characters per screen. So clarity is everything.

Sample menu for a SACCO USSD:

markdownCopyEditWelcome to JuaKali SACCO
1. Check Balance
2. Loan Application
3. Pay via M-PESA
4. Customer Support

Best practices:

Limit to 3–5 menu items per screen
Avoid jargon
Number each option
Use consistent structure across screens

Tools like draw.io, Figma, or even flowchart templates in PowerPoint are great for mapping menus.

Mobulk Africa also offers USSD menu design consultation.

Step 4: Choose a USSD Aggregator or Platform Provider

Telcos (Safaricom, Airtel, Telkom) do not directly offer USSD development services to businesses. You’ll need to work with a licensed USSD aggregator like Mobulk Africa, which:

Applies for the USSD code on your behalf
Builds, hosts, and maintains the USSD application
Connects your USSD to payments, databases, APIs, and CRMs
Ensures compliance with CAK (Communications Authority of Kenya) rules

Mobulk Africa’s Advantages:

Works across all telcos (multi-network)
99.99% uptime infrastructure
Local support teams in Nairobi
Real-time analytics dashboard

Step 5: Develop and Test Your USSD Application

Development can be done in several languages and frameworks:

PHP with USSD SDKs
Python (Django or Flask)
JavaScript (Node.js)
Java (Spring Boot for enterprise-grade apps)

If you don’t have an in-house team, Mobulk Africa provides full-stack USSD development and API integration.

Testing checklist:

Menu navigation works correctly
Timeout handling (typically 20 seconds of inactivity)
Responses are under 3 seconds
Multi-language support (e.g., English, Kiswahili)

Use simulators before going live, then do limited closed testing with real users.

Step 6: Apply for Short Code Approval via Aggregator

If you’re using Mobulk Africa, we handle this entire step — including:

Submitting your application to Safaricom, Airtel, and Telkom
Handling technical specifications
Ensuring compliance with Kenya’s SIM Registration and DND (Do Not Disturb) regulations
Coordinating with CAK for regulatory approvals if necessary

Time to approval varies:

Shared code: 3–7 business days
Dedicated code: 10–21 business days

Step 7: Go Live and Monitor Performance

Once approved and connected to telco networks, your USSD code is ready for public launch.

Post-launch actions:

Train your customer support team
Market the short code aggressively (SMS blasts, posters, website banners)
Monitor usage through the Mobulk Africa dashboard
Optimize menu structure based on user behavior

USSD Integration Options

USSD doesn’t work alone. It can plug into:

M-PESA STK push API for payments
Customer databases to fetch account data
CRM tools for support ticket creation
SMS fallback systems to notify users after session

Mobulk Africa supports these integrations out-of-the-box or via custom API work.
