One of the benefits of using Google's address standardization api is its ability to validate addresses in multiple languages and global regions. Google's address validation services use Google Street Cars as a source of address data, but this is not the best data source for accurate geolocation. Update frequency of Street Cars is dependent on their map updates, and location biasing is not an option. You'll need to use a third-party address validation service to get accurate addresses from this source.
In addition to standardizing addresses, Google's address parsing API also provides delivery-status and detailed information about invalidated addresses. You can use the Address Bulk Verification API to upload up to 100K addresses for validation. Address Bulk Verification is asynchronous, and sends a callback once the processing is complete. Address standardization and validation are critical to ensuring a high-quality customer experience.
While address validation and standardization are both necessary steps, the latter isn't as important as the former. Address validation is the process of comparing a given address against a trusted database, such as the USPS. If it matches the database, it's a valid address. Otherwise, it's an invalid address. This happens even when an address is physically present. Invalid addresses might have multiple addresses and may not match an authoritative database.
Address autocomplete APIs can be used for address verification, but they're not a substitute for a postal service. Aside from standardized address data, these services can also save developers time and reduce the likelihood of shopping cart abandonment. The Google address standardization API will standardize latitude and longitude for a single address. Ultimately, it will provide a more convenient experience for customers and decrease the risk of shopping cart abandonment.
