House number and street example

Updated: March 3, 2026

A house number and street example demonstrates how a street address is typically written using a numeric identifier followed by the street name. For example, “221B Baker Street” or “1600 Pennsylvania Avenue NW” shows how the house number uniquely identifies a location along a street.

House numbers usually appear before the street name in many countries, but this order is not universal. Some regions place the house number after the street name or integrate it differently into the address structure.

House numbering systems often follow logical patterns. Odd and even numbers may appear on opposite sides of the street, and ranges may indicate how addresses are distributed geographically. These patterns help postal services and navigation systems estimate location even when an exact address is missing.

Accurate handling of house number and street data is essential for address validation and delivery. Missing or misplaced house numbers are one of the most common causes of failed deliveries and validation errors.

Structured address datasets define how house numbers and street names should be combined, validated, and formatted. This ensures that examples translate correctly into real-world address processing across different postal systems.

Address validation powered by GeoPostcodes’ global ZIP code data

Address validation is the process of checking whether an address is complete, correctly structured, and aligned with official postal and administrative reference data. A validated address confirms that core components such as street name, house number, city, postal code, and country exist and match authoritative sources.

This matters because inaccurate addresses lead to failed deliveries, higher logistics costs, duplicate customer records, and inconsistent reporting across systems. Reliable address validation supports operational efficiency in logistics, e-commerce, financial services, marketplaces, and analytics workflows.
