Different locations require different information in their addresses. In Japan, for example, a person&#8217;s postal address is written in order&nbsp;<a href=\"https:\/\/www.realestate-tokyo.com\/living-in-tokyo\/japan-info\/japanese-address\/\" target=\"_blank\" rel=\"noreferrer noopener\">from the largest administration or geographical unit to the smallest<\/a>, with the name of the customer at the very end. However,&nbsp;<a href=\"https:\/\/www.post.japanpost.jp\/int\/use\/writing\/normal_en.html\" target=\"_blank\" rel=\"noreferrer noopener\">Japan Post recommends<\/a>&nbsp;that you write the address in reverse order if you&#8217;re using Roman script or English.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Address Normalization Across Countries<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Address normalization across countries is another challenge in <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/international-address-validation\/\" target=\"_blank\" rel=\"noreferrer noopener\">address validation<\/a>. In Belgium, for example, the postal service recommends using&nbsp;abbreviations for multi-flat buildings&nbsp;and only if the line is&nbsp;longer than fifty characters. In France, the postal service recommends writing the&nbsp;last three lines in uppercase. Preferences like these are different in almost every country and postal system.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Common Inaccuracies and Impacts<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Deviating formats, incorrect mandatory fields like postal codes, outdated or incomplete addresses, and issues arising from translating one language to another are all inaccuracies that can lead to delays in service, incorrect billing, and other negative impacts on customer experience.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Financial Implications<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Additionally, the costs of being unable to reach your customers to inform them of service or billing updates, and shipping something to an incorrect address can add up. Back in 2025, it was already estimated that the cost of a bad address is between&nbsp;<a href=\"https:\/\/www.easypost.com\/blog\/2015-07-15-the-cost-of-bad-addresses\" target=\"_blank\" rel=\"noreferrer noopener\">$35 and $70 per package<\/a>, and that\u2019s just for domestic mail. It\u2019s easy to imagine how much higher that cost could be when including international costs like tariffs or overseas shipping.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Benefits of Validated Addresses<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Validated addresses also enable <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/spatial-analysis\/\">geospatial analysis<\/a>, which can make your business more efficient in various ways. For instance, you can <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/supply-chain-master-data-management\/\" target=\"_blank\" rel=\"noreferrer noopener\">optimize delivery routes<\/a> and timing as well as accurately calculate how many customers live in a specific area or within a certain distance of a location.<\/p>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-do-you-validate-an-international-address-\">How Do You Validate International Addresses?<\/h2>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>First, acknowledge that there are <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/international-address-data\/\" target=\"_blank\" rel=\"noreferrer noopener\">many ways to write the same address<\/a>. There are some commonalities, yes. For example, most address forms require a country. But as can be seen from the example of Japan, even the same country will sometimes have inconsistencies.<\/p>\n\n\n\n<p>To attempt the problem of validation, you need to understand a <a href=\"https:\/\/public.geopostcodes.com\/international-zip-code-formats-download\" target=\"_blank\" rel=\"noreferrer noopener\">country&#8217;s address formats<\/a>, along with their variations and exceptions.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"the-components-of-an-international-address\">The Components of an International Address Data<\/h3>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>An international address has&nbsp;<a href=\"https:\/\/www.iso.org\/obp\/ui\/#iso:std:iso:19160:-4:ed-1:v1:en\" target=\"_blank\" rel=\"noreferrer noopener\">several components<\/a>&nbsp;managed by different administrative bodies. The <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/the-quickest-way-to-build-an-address-autocomplete-api\/\" target=\"_blank\" rel=\"noreferrer noopener\">tool you use for address validation<\/a> needs to understand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Which components make up the address of a particular country<\/li>\n\n\n\n<li>Which components are optional, or optional but recommended<\/li>\n\n\n\n<li>Which components are mandatory<\/li>\n<\/ul>\n\n\n\n<p>It&#8217;s tempting to think that catering for these variances is easy. You would simply add some optional fields and make them mandatory for certain countries, as Amazon.com did for an address in Japan in the example below:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"573\" height=\"748\" src=\"https:\/\/www.geopostcodes.com\/en-GB\/wp-content\/uploads\/2023\/05\/address-validation-of-japan-in-amazon.jpg\" alt=\"Japan address validation example - GeoPostcodes\" class=\"wp-image-4867\" srcset=\"https:\/\/www.geopostcodes.com\/en-GB\/wp-content\/uploads\/2023\/05\/address-validation-of-japan-in-amazon.jpg 573w, https:\/\/www.geopostcodes.com\/en-GB\/wp-content\/uploads\/2023\/05\/address-validation-of-japan-in-amazon-230x300.jpg 230w\" sizes=\"(max-width: 573px) 100vw, 573px\" \/><\/figure>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>This common solution hides the complexity of different address formats on the front end, but it doesn&#8217;t resolve the complexity of having to validate these addresses. It also introduces further challenges. For instance, if users don&#8217;t see an address in the format they are used to, they will not know where to enter which values.<\/p>\n\n\n\n<p>So even though Amazon.com uses the format above when you want to deliver something to Japan, Amazon.co.jp uses the following format, which will make sense to someone from Japan:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"581\" height=\"617\" src=\"https:\/\/www.geopostcodes.com\/en-GB\/wp-content\/uploads\/2023\/05\/address-validation-in-japan-from-amazon-eu.jpg\" alt=\"Amazon address validation example Japan - GeoPostcodes\" class=\"wp-image-4873\" srcset=\"https:\/\/www.geopostcodes.com\/en-GB\/wp-content\/uploads\/2023\/05\/address-validation-in-japan-from-amazon-eu.jpg 581w, https:\/\/www.geopostcodes.com\/en-GB\/wp-content\/uploads\/2023\/05\/address-validation-in-japan-from-amazon-eu-282x300.jpg 282w\" sizes=\"(max-width: 581px) 100vw, 581px\" \/><\/figure>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>In the Amazon.com example, it&#8217;s not clear where to add the mandatory prefecture field, the 000-0000 format isn&#8217;t enforced, and should&nbsp;<strong>Chome, Banchi, Go<\/strong>&nbsp;be populated in the first or second street address line? Also, the native Japanese format moves from general to specific, like zooming in on a map, until you get to the address. Someone who is used to this format could easily get confused when they have to start at the street level and zoom out to the country level.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"address-lookup-by-country\">Address Lookup by Country<\/h3>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Broadly speaking, there are two main methods for <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/international-address-validation\/\" target=\"_blank\" rel=\"noreferrer noopener\">validating international addresses<\/a>. Both require that you first look up the address format of the country in question. You can then either use vendor-provided APIs to validate an address or <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/the-quickest-way-to-build-an-address-autocomplete-api\/\" target=\"_blank\" rel=\"noreferrer noopener\">your own custom validators<\/a>.<\/p>\n\n\n\n<p>Let us examine both these methods.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"look-up-formatting-through-third-party-apis\">Look Up Formatting through Third-Party APIs<\/h4>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Third-party vendors can validate your international address list, usually by making an API call. Some of these vendors respond with formatted and enriched data, while others use machine learning and artificial intelligence to correct potential errors within an address. Regardless of the methodology, the result you get is a trustworthy validation of an address.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Drawbacks of External API Calls<\/strong><\/h4>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>A downside of this method is that making external API calls for validating addresses can significantly slow down your website, affecting the user&#8217;s experience. External API calls can also impose rate limits and come at cost. This cost will sometimes be hard to predict as it\u2019s directly related to the number of calls you\u2019ll make.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"look-up-formatting-through-raw-data\">Look Up Formatting through Raw Data<\/h4>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The alternative to using a third-party API is to write custom address validators. To do this, you need to take into account different geographies, exceptions to addressing rules, language barriers, and so on. You can run addresses in your raw data across those validators to see whether each address is valid.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Challenges of Static Data<\/strong><\/h4>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>However, only using static, raw data to create the validators is problematic. Names of cities, streets, and counties keep changing. Their boundaries might also be reorganized every so often. If you use a static formatting data lookup method, you must keep the raw data updated to ensure you can validate addresses accurately.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Historical Accuracy<\/strong><\/h4>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>You also need to keep accurate historical records since place names can change. In February 2026, the city of Port Elizabeth in South Africa was&nbsp;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Gqeberha#:~:text=In%202019%2C%20the%20Eastern%20Cape,that%20flows%20through%20the%20city.\" target=\"_blank\" rel=\"noreferrer noopener\">renamed as Gqeberha<\/a>. However, people who have lived there for years are not necessarily going to change their habits overnight. It might take them years to get used to using the new name. And if someone is shipping to them from abroad, they are unlikely to know about this location change. Your validation, therefore needs to have records of the current name and previous ones to validate addresses accurately.<\/p>\n\n\n\n<p>Because of these <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/blog\/the-7-challenges-of-building-a-standardized-zip-code-database\/\" target=\"_blank\" rel=\"noreferrer noopener\">challenges<\/a>, it&#8217;s best to use vendor-provided raw data. However, remember to refresh the data frequently to incorporate changes like renaming, new suburbs, and so forth.<\/p>\n\n\n\n<div style=\"height:60px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-do-you-need-to-build-your-own-international-address-validator-\">What Do You Need to Build Your Own International Address Validator?<\/h2>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Creating an address validator is like creating an advanced pattern-matching program.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Deterministic Matching<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>First off, there are many techniques you can use. For instance, deterministic matching involves the precision matching of different parts of an address with an up-to-date city and <a href=\"https:\/\/www.geopostcodes.com\/en-GB\/street-address-database\/\" target=\"_blank\" rel=\"noreferrer noopener\">street-level database<\/a>. <\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Fuzzy Matching with Levenshtein Distance<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>You could also use Levenshtein distance calculation for partial or fuzzy matching, where you take into consideration small mistakes in the addresses, such as an extra blank space or a minor spelling mistake.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Implementing Custom Validators<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Building a custom validator involves coding one or more of these matching techniques into a library. Different applications, services, and users can then use the library to validate addresses based on their own use cases.<\/p>\n\n\n\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reliable Data Sources<\/strong><\/h3>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>Another non-negotiable component of an international address validator is a trustworthy, accurate data source, such as&nbsp;<a href=\"https:\/\/www.geopostcodes.com\/en-GB\/\" target=\"_blank\" rel=\"noreferrer noopener\">GeoPostcodes<\/a>.
