How Does An Address Lookup Tool Work?

Moreover, sometimes, they also need to double-check international mailing addresses to serve their global clients in a better way.

Verifying international addresses need you to access several global address formats, geospatial data points, etc. Not surprisingly, each country has its own set of address standardization guidelines that you need to follow. In these situations, international address lookup can come to your rescue.

It helps you access the authoritative databases of that country and format addresses correctly. For example, if you are mailing to the US, you need to access the USPS database for a US address lookup.

There are three main steps in the address lookup process, including:

  • Address parsing: It is the process of breaking down an address into elements, like street name, municipality name, state or province, and postal code. Parsing helps the address lookup tool label each part and check their authenticity separately.
  • Address standardization: Address standardization is one of the most crucial steps in Post Office address lookup. It arranges an address according to the destination country’s format, language, and alignment to help you mail worldwide. For example, you need to use the Canada Post format for sending items within Canada, the Royal Mail format to mail to the UK, the USPS format to mail to the US, etc.
  • Address Verification: It is the final and prime step in the address lookup process. It takes a standardized mailing address and looks it up in an official database to confirm its accuracy. An effective address lookup API like PostGrid can add missing postal codes, correct misspellings, eradicate other errors, and make your addresses deliverable.
