What is International Address Verification?

International address verification is the process wherein—a non-US address is compared with an authoritative database of another country, where the address is located and then verified accordingly. It is similar to local address validation in which addresses are compared and matched with the data obtained from the USPS. It is incredibly important to companies that have international clients or are running an international business.

Problems Associated With International Address Verification

It is a popular assumption that international address verification is simply to connect with the databases of other countries and cross-check the required details. In reality, it is not so simple—international address verifications can be complicated.

  • Address Formatting – As far as the US is concerned, the address formats are kept simple – apartment number, street, city, state, zip code. However, it is not the case with other countries. Many countries have two different format categories for rural and urban locations, with various other internal formats within them. Countries like China, further have different standards for different formats. It makes it difficult to format addresses accordingly. Also, what we refer to as ‘states’ are ‘provinces’ for some countries.
  • Language – Half the world uses Latin characters to write addresses, the remaining half uses characters from their native language. The language barrier is a huge challenge before an international address verification tool.
  • Delivery Point Data – Most countries in the world do not make use of the DPV (Delivery Point Validation) system. Hence, it is very difficult to organize international addresses according to their validity.
  • Destination Country – For accurate validation, there has to be a value included in the entered address representing the destination country. It should either be an ISO classification or the country’s full name. A lot of times, these requirements are not fulfilled – making verification difficult.

PostGrid always makes sure to stay updated and solve all these problems for you with its high-end features.
