How Street Naming and House Numbering Works

Street naming and house numbering may look like small details, but they are very important for how a city or community functions. Without clear street names and visible house numbers, people struggle to find homes, deliveries get lost, and emergency services waste valuable time.

As Nigerian cities continue to grow and more people use logistics services, ride-hailing apps, and online shopping, having a proper address system has become a necessity, not a luxury.

This guide explains how streets are named, how houses are numbered, who is responsible, and why it matters using simple explanations and bullet points for easy understanding.

What Is Street Naming and House Numbering?

Street naming and house numbering is the system that gives every road and building a unique identity so they can be easily located.

In simple terms:

Street = gets a name
House = gets a number
Both combine to form your address

Example:

No. 15, Peace Avenue, Unity Estate, Surulere, Lagos

Who Is Responsible?

Street naming and numbering are handled by local authorities and planning offices.

Usually managed by:

Local Government Authorities (LGAs)
Town planning departments
Surveyors
Urban planners
Community development associations

Their duties include:

Approving street names
Creating maps
Assigning numbers
Installing signage
Keeping address records

How Street Names Are Chosen

Street names are selected carefully to avoid confusion and reflect the community’s identity.

Common naming ideas:

Historical figures
Community leaders
National heroes
Cultural or local language names
Landmarks or rivers
Positive words like Peace, Unity, Freedom, Victory

Rules often followed:

Must be unique
Easy to pronounce
Easy to spell
Not offensive
Not too similar to another street nearby

The Street Mapping Process

Before naming or numbering begins, authorities must first map the area properly.

Steps involved:

Land survey
Road layout planning
Marking intersections
Identifying plots
Creating official maps

Why mapping matters:

Prevents numbering mistakes
Helps emergency services
Supports digital maps and GPS
Makes future development easier

How House Numbering Works

Once streets are named, each building is assigned a number using a logical system.

The Most Common Numbering Method (Odd–Even System)

This is the system used in most modern cities.

How it works:

One side of the street = odd numbers
Other side = even numbers

Example:

Left: 1, 3, 5, 7, 9
Right: 2, 4, 6, 8, 10

Benefits:

Easy to predict locations
Faster for deliveries
Faster for emergency response
Less confusion

Direction of Numbering

Numbers follow a clear direction.

Usually:

Starts from the main entrance or major road
Increases as you move forward

This means:

Smaller numbers = closer to entrance
Larger numbers = farther inside

Other Numbering Styles You May See

Some older areas or estates use different formats.

Examples:

Plot numbers (Plot 10, Plot 11)
Block and flat numbers (Block B, Flat 3)
Crescent or Close numbering
Compound numbering

But modern systems prefer:

Clear street numbers
Sequential order
Easy identification

Installing Signs and House Plates

Names and numbers must be visible to be useful.

Street signs:

Fixed at corners
Placed at intersections
Large and readable

House numbers:

Mounted on gates or walls
Visible from the road
Not hidden by plants or paint
