Part of doing business worldwide is making sure that your databases are correct. Without the proper formatting and accurate international address information, your marketing data, package delivery and business correspondence will be ineffective. AddressDoctor's address standardization software allows you to perform foreign address verification on your data and to correct postal addresses from countries around the world.
Our unique software compares your addresses with a reference database. The AddressDoctor reference database currently covers more than 240 countries and territories. Almost every country on the planet is included, allowing you to verify postal address information before you send out letters, packages and direct mail advertising.

AddressDoctor's reference database is comprehensively updated more than 600 times each year. The most reliable and official suppliers and experts worldwide always keep it current. When choosing our data sources, national postal organizations and official correspondents are our primary sources.
