What is International Address Verification?

International address verification is a process that involves comparing an address against the postal regulations of the country the address is located. It is similar to validating addresses when talking about the US. An International address validation tool helps you validate addresses when an address match is found in a country’s database.

Problems Associated With Verifying International Addresses

It is a popular assumption that international address validation 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, and zip code. However, it is not the case in 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, and 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.

National Vs. International Address Verification

As the name suggests, national address verification refers to the process of address validation within the country based on the national postal authority standards. Addresses within a country are validated using standards set by the national postal authority, as the name implies. Among the national postal authorities in the US is the USPS, which sets postal address standards for the entire country.

Below is an example of an address input by the user along with the standardized version of the same mailing based on the US Postal Service guidelines:

Customer’s Address:
PO Box 123456,
Tampa, Florida

Standardized Address As Per US Postal Service:
PO Box 12346,
Tampa, Florida

International address verification is the process of verifying an address for a package that is being shipped outside of the U.S. against records of trustworthy postal authorities abroad.

What Does International Address Verification Mean?

Imagine a scenario where you run an US_based company that wants to send or mail an item to Hong Kong. The address of the customers will first be requested by the service provider. Once this information is provided, the company will contact the customer. An international address verification provider will help you with shipping. They will also compare the database to determine the accuracy of the customer’s address with the local postal standards of the country.

An international address check confirms that a match is found in the database and is valid. Verification can be a lengthy, rigid, and daunting process. So, verifying an address that does not belong to a country makes things twice as challenging. The truth is that international postal addresses are not standardized.

When choosing a provider for the International address verification, you should remember that not all countries give you street-level addresses. And not all service providers understand the depths of verifying street-related information. Even the ones that provide different formats for different postal or customer data.

Here, PostGrid’s address verification service includes a powerful restful API to help you parse, standardize, verify, cleanse, and format address content. Now, send your mailings easily from the USA to Hong Kong and anywhere in between with our USPS compliant and International bulk address verification APIs.

What to Consider When Selecting a National & International Address Validation Service Provider?

Well, national and international address verification is a little expensive, depending on the mailing routes. Furthermore, not all providers verify international and national postal addresses. In case, you wish to mail items internationally, find a provider that offers both national and global validation. PostGrid helps you with everything under one roof rather than two different companies, depending entirely on your needs.

Now, that being said, below are a few aspects that you must look for when selecting national and international address validation service providers:

Scalability & Accuracy:

USPS and CASS track thousands of address changes every day, and they do a fantastic job of it. It is also the responsibility of the service providers to ensure that their databases are updated regularly. Providers must stay on top of all the changes in the customer’s location, and updated information gives a real picture of the customer.
PostGrid updates its database from USPS at least once a month. Our tool works hand-in-hand with the USPS and guarantees you the quality of the database! For international verifications, we update our API according to various updates & authoritative schedules of different countries.
