What Is An Address Verification API?
Address verification is the process of checking the accuracy of a person's address. It can be a useful service for businesses that send mail to their clients. Incorrect addresses can lead to a poor user experience and can result in failed deliveries. Increasing customer satisfaction through address verification can also help businesses reduce their shipping costs.
An address verification API is a web service that uses an HTTP GET request method to verify the validity of an address. Once the address is submitted, the API searches the official database of the United States Postal Service. This database contains over 160 million addresses.
For addresses that are not in the database, a private delivery company will validate the address. If the address is valid, the address will be returned. The result of this process will include the normalized address, a real-world address, and the standardized address.
The API can also provide annotations, which tell users whether the address was validated correctly or not. These annotations will inform users of errors or other deficiencies.
Many businesses, including delivery companies, use an address lookup API to verify addresses. These APIs work by searching a number of different databases. They can include demographic data, geographic information, and other address-related databases.
Some address verification APIs also standardize addresses and remove duplicate addresses. They can also correct typos. This is helpful to eliminate redundancy in customer communication.
Address verification is important to businesses that deal with customers globally. It can minimize the time spent addressing packages, and can make it easier for the customer to communicate with the business.
