What is Address Verification? Address validation ensures that a person's address is valid, formatted correctly, and contains all the necessary information in a database. Invalid addresses are not real and can't be corrected, while valid addresses are those that are already on file. Address validation can be performed in batch or real-time. In either case, a clean data set will increase customer service and boost business efficiency, and reduce unnecessary costs.
An invalid address can be either a fake or a non-existent address. These are common mistakes made by people entering addresses. They might enter an incorrect street name, a mixup in house numbers, or a completely different address entirely. These mistakes can be corrected using advanced address verification tools. For example, a person typing an address incorrectly may have entered the address incorrectly in an email, or a website might have entered the wrong information.
Address validation begins with a standardization process. Addresses are broken down into constituent parts and checked for spelling errors. This process may vary by address verification tool. For example, a software tool might convert street suffixes to avenues. For other purposes, an address may have state or street suffixes. Regardless of the way in which it is processed, it's important that the address is correct.
Fortunately, there are a number of tools available for this process. Address verification APIs can be used to detect typos, missing information, and missing letters. They're particularly useful for mobile environments, where address information can be inaccurate. Fuzzy matching, which uses an algorithm to match addresses, is another useful tool. And reverse geocoding can assign a geographical coordinate system to an address. So, if you're using address verification, be sure to select a CASS-certified address verification tool.
