Data Cleansing and International Address Standards

In the digital age, data is a critical asset for any business. Clean, accurate data is essential for effective communication, streamlined operations, and enhanced customer experiences. Data cleansing involves detecting and correcting (or removing) corrupt or inaccurate records from a database. It ensures that your data is consistent, accurate, and useful. Integrating address lookup software into your data management practices is also essential for maintaining accurate and up-to-date address data.


Data cleansing can help in various ways:

  • Improved Accuracy: Ensures all data entries are correct and complete.
  • Enhanced Efficiency: Streamlines operations by eliminating errors and inconsistencies.
  • Better Decision-Making: Provides a reliable basis for analysis and strategy.
  • Cost Savings: Reduces the costs associated with incorrect data, such as returned mail or undeliverable shipments.
  • Customer Satisfaction: Enhances customer experience by ensuring accurate delivery information and personalised communications.


Using address lookup software can significantly enhance the accuracy and reliability of your data. This is especially important for businesses that handle large volumes of customer information and need to ensure that all addresses are correct and formatted properly.


 What is UPU S42 and Why Should You Care?


Now that we understand the importance of data cleansing, let's delve into UPU S42 and its relevance in this context.


First, what does UPU stand for? The Universal Postal Union (UPU) is the second oldest international organisation in the world, founded in 1874. (For context, the oldest is the International Telecommunications Union, founded in 1865.) With 192 member countries, the UPU’s mission is to bring standardised and efficient postal systems to countries around the world. The organisation helps member countries develop and implement addressing standards and grow their mail, parcel delivery, and financial services. The UPU acts as a forum for international discussion and collaboration in the postal sector.


UPU S42 is the international addressing standard developed by the UPU’s Postal Operations Council and experts from its Addressing Group. It breaks down postal addresses into the generic component parts commonly used by all UPU member countries:

GIVEN NAME > SURNAME > STREET NUMBER > STREET NAME > STREET TYPE > FLOOR > TOWN > REGION > POSTCODE > COUNTRY


The second section of UPU S42 provides templates of how these components are arranged according to the standards of each country. With over 200 different addressing systems in the world, this database is vital as it provides a framework by which international shipments can be efficiently processed.


Implementing UPU S42 standards in data cleansing solutions ensures that addresses in customer databases are not only validated but also reformatted, where necessary, to the precise standards of their country.


A simple example is addresses in Germany, where the street number generally comes after the street name. If someone in the UK types in a German address, they may use their local form and place the street number first. After data cleansing, the address will be formatted in the standard format for Germany.


Locally formatted address:
Hienz Wolff
167A Königstraße
Berlin
14109


Standardised address for Germany:
Hienz Wolff
Königstraße 167A
Berlin
14109

 

Why is this important? 

 

Collecting data in your chosen format, likely the standard format of your country’s address system, might result in technically valid but improperly ordered data for the destination country, potentially causing delivery delays.


Data cleansing verifies the format of every address as an automatic step in data processing systems. This is particularly vital for logistics and fulfilment companies that do not capture address data directly from customers but receive orders via retailers. Validating address data and ensuring the correct format for the destination country streamlines shipments and reduces lost or delayed deliveries.

An article in Ecommerce News recently put a number to something every online retailer dreads: lost parcels. In Q4 2024 alone, European ecommerce retailers lost €500 million in revenue due to 3.72 million undelivered parcels. That’s roughly €145 per parcel in direct and indirect logistics costs. And while the official rate of “lost” parcels is just 0.06%, the reality – accounting for misdelivery, theft, and reporting gaps – is likely closer to 0.7%. That’s 1 in every 143 parcels. The Hidden Costs of a 'Lost' Delivery For enterprise-scale ecommerce operations, the implications scale fast: Lost product and packaging costs Repeat fulfilment and reverse logistics Customer service team time and refunds Increased churn and checkout abandonment Damage to brand reputation and online reviews So Why Are Parcels Going Missing? Many issues originate in the last mile of the delivery process. The root cause is often poor data quality: Incomplete or inaccurate delivery addresses captured at checkout Manual amendments to address fields by warehouse or courier staff Ambiguous delivery locations (e.g., "front porch") Lack of precise geolocation data for drop-off Inadequate or unverifiable proof of delivery Some losses are unavoidable, but most stem from gaps in ecommerce data validation and fulfilment process transparency. What Retailers Can Control with Smart Logistics Data While you can’t eliminate theft or accidents, you can reduce missed deliveries and failed first attempts through better data validation and delivery insights: Real-Time Address Validation at Checkout Fetchify’s ecommerce address validation tools connect directly with official data sources including Royal Mail PAF and the Multiple Residence dataset. This ensures accurate delivery details for apartment blocks, HMOs, student housing, and more. Unlike generic autocomplete tools, this is verified delivery point data. Rooftop-Accurate Geocoding for Pinpoint Delivery Fetchify’s Rooftop Geocodes assign precise latitude and longitude to verified addresses – helping carriers reach the exact doorstep, not just the postcode centroid. Proof of Delivery with Location and Time Stamping Our data solutions integrate seamlessly with POD technologies, supporting timestamped, geo-tagged delivery images. Customers can also submit geo-located photos during disputes, enabling faster, fairer resolutions. Map-Based Address Confirmation for Shoppers By embedding a zoomed-in map in the checkout process, ecommerce brands allow customers to visually confirm their delivery location. This prevents ambiguous or misentered addresses from the start. Audit Trails and Address Change Tracking Fetchify tracks address field edits and changes across the fulfilment chain, helping to pinpoint where a delivery went wrong and maintain data accountability. Marginal Gains. Major Ecommerce Impact. Smart logistics and address data validation might only reduce parcel loss by fractions of a percent – but the impact is huge: A 0.1% improvement = thousands of saved parcels = millions in recovered revenue Fewer failed deliveries = less pressure on customer support teams Accurate addresses = better first-time delivery success and lower last-mile costs Conclusion: Delivery Accuracy is a Data Challenge Lost parcels aren’t just a logistics challenge. They’re a symptom of poor data validation in ecommerce. From checkout to doorstep, the journey must be powered by precise, verified data. Fetchify helps online retailers solve this problem with address validation, geolocation, and enhanced fulfilment transparency. If you want to stop asking “Whose front door is this?” – start with smarter ecommerce data. Want to improve delivery success and reduce failed parcels?
