Global Address Validation Service

The process to ensure that the addresses captured by a form are accurate and complete.

It involves comparing the new address against a comprehensive and up-to-date database of valid addresses. This can be done in real-time (i.e., during online transactions) or integrated into backend systems to ensure that addresses are accurate before further processing.

Other vendors collect USPS information and resell it. The GeoPostcodes Postal database differs from that of USA data by the additional features and services, for instance, the multi-language support, the geocodes, and the time zone information.

Your address validation process can vary depending on your specific needs, the number of addresses, and your budget. Some common methods are:

• Database Checks: Integrate an on-premise database like GeoPostcodes’ to perform periodical validation checks.
• Postal Services: Validate one single address at a time. Not useful for batch verification.
• Third-Party Services: Integrate address validation into your applications, websites, or databases through an API (Application Programming Interface).
• User Input Validation: Validate shipping during the input process on your website or application.

The cost of an address validation software can vary widely depending on several factors like the accuracy, the added features, or the software integration. Some providers require pay-as-you-go pricing, whilst others require a yearly subscription or license fee.

The United States Postal Service (USPS) offers address validation and correction services through the USPS Address Information API (Application Programming Interfaces). This paid API allows businesses to verify addresses and standardize addresses against USPS data.

By matching the provided billing ZIP code with the one associated with the card on file, merchants can reduce the risk of fraudulent transactions.

Google provides some limited free usage of its address validation services. However, it’s important to note that there are usage limits associated with the free tier, and exceeding these limits will result in charges.

Address validation confirms that the addresses in a database are real and unified. It includes features like correcting input addresses or standardizing formats among registered addresses.

Alternatively, address verification goes one step further and ensures the address is connected to the individual who provided it. This can be done using address verification software. 

An address validation API is a software interface that allows developers to integrate address verification and validation capabilities into their applications, websites, or systems. The process requires the implementation of the API into a software or application.

A query is placed per address verified. The API returns a response to the application, indicating whether the address is valid, complete, and deliverable. The API may provide suggestions or corrections if there are any errors or issues with the address.
