Nairobi’s public transport system relies heavily on route numbers, a structure that guides millions of commuters every day. From matatus to buses, these numbers help passengers identify destinations quickly and move across the city efficiently.
If you regularly commute in Nairobi, you likely board a matatu or bus using a familiar route number. However, few people know that the numbering system dates back decades and was designed to bring order to the city’s growing transport network.

Origins of Nairobi’s Route Number System
The history of route numbering in Nairobi goes back to 1934 when Kenya Bus Service (KBS) began operating in the city. To manage operations effectively, the company introduced numbered routes based on destinations.
The system was designed to help both operators and commuters navigate the expanding urban transport network. Over time, these numbers became deeply embedded in Nairobi’s transport culture and remain in use today.
The Three Original Route Categories
The early numbering structure divided routes into three main groups:
- Urban routes – linking residential estates on the outskirts to the city centre
- Intra-urban routes – connecting different estates within Nairobi
- Peri-urban routes – extending beyond Nairobi to neighbouring towns and satellite areas
This categorisation helped streamline movement and improve route identification.
Some of Nairobi’s Earliest Routes
Several early routes became popular and are still recognised historically:
- Route 7: Jericho to Kenyatta National Hospital
- Route 8: Jerusalem to Kenyatta National Hospital
- Route 1: City centre through Community to Dagoretti Corner, Karen and Dagoretti Market (now defunct)
Over the years, transport demand and road changes led to adjustments, with some routes disappearing altogether.
Who Assigns Route Numbers Today
Currently, the National Transport and Safety Authority (NTSA) oversees route allocation. The authority assigns route numbers to registered matatu Saccos and regulates operations to maintain order.
Rather than creating entirely new routes, the focus is on managing existing ones and ensuring compliance.
Why Some Routes Share Numbers
Commuters often notice that some routes use the same numbers despite serving different destinations. For example:
- Route 33 serves both Embakasi and Ngumo
- Route 125 and 126 both head towards Rongai
Originally, these numbers distinguished final destinations. Route 125 ended in Ongata Rongai, while 126 extended to Kiserian. Over time, operators blurred these distinctions, creating confusion for passengers.
A System That Continues to Evolve
Some routes have been phased out due to changing travel patterns, infrastructure upgrades, and transport restructuring. Despite these adjustments, the matatu system continues adapting to Nairobi’s growing population.
The industry itself remains uniquely Kenyan, known for vibrant designs, loud music, and branded vehicles. Beyond culture, matatus continue to provide affordable mobility for most city residents.
Commuter Impact & Advice
- Always confirm destination verbally, not just the route number
- Watch for variations like short-turn or extended routes
- Use known stages to avoid confusion on shared numbers
- During peak hours, ask conductors final drop-off points
- Follow updates from NTSA and Saccos on route changes
For daily commuters, understanding route numbering can reduce confusion, prevent boarding wrong vehicles, and save time—especially on routes with shared numbers.
