International Address Data

Verify Global Data via a single service on the Hopewiser Portal


Hopewiser’s International addressing service allows users to verify and capture addresses from 242 countries around the world. Capturing accurate, global customer addresses means you can quickly and easily process the data for deliveries, marketing purposes and business analysis.

Ecommerce checkout and form conversions will increase, plus, failed deliveries and mailings are reduced, which in turn improves brand satisfaction and business productivity.

International data is accessed within our cloud self-service Portal.  Using our easy-to-use software you will be able to:-

  • Capture and verify accurate customer address data from 242 countries
  • Use the highest quality address data when available for the relevant country
  • Access a single service which includes all countries
  • Gain an understanding of the address quality available on a per country basis
  • Support both alpha-2 and alpha-3 country codes
  • Where localised address formats are known and the coverage level permits, these are applied to the returned address label
  • Access accurate geocodes where available

The API automatically updates so you will always have access to the latest International data available.

The Difference in Global Address Formats

There is no one Global address format. In almost every country, the address format differs. Even if the differences between the respective formats seem small, not only the correct elements of an address, but also their hierarchical alignment can play a big role. Only with the right software, can you be sure that a mailing gets to its addressee.

For instance, Germany has strict rules about receiving mail, which, if ignored, may result in your mail being returned to you with no attempt at delivery. When addressing mail to Germany, always:

  • Use the new five-digit postcode (using an old four-digit postcode will cause delay)
  • Put the postcode before the town name
  • Put the house number after the street name

In USA, if only the first half of the postcode/zipcode is known, this will be sufficient, although both parts are preferred. The abbreviation USA is also acceptable.

So how do you ensure your International data is correct?

With over 242 countries available to validate, you need software that will format into the correct structure and secondly verify against available address data for the relevant country. Hopewiser’s Portal offers this service via a Desktop Client, REST API or JavaScript Client.
