The Importance of Address Exception Handling

Exception handling is a critical aspect of any business dealing with address data. This process ensures that your system still functions effectively, even when confronted with valid addresses not present in the validation system.

Impact on Your Business

Ignoring address exceptions can lead to missed business opportunities and potential delays in service delivery. It can also lead to an accumulation of unsuccessful transactions or returns, negatively impacting your bottom line.

Impact on Customer Satisfaction

Address exception handling is vital to maintaining high levels of customer satisfaction. When an address doesn't validate, it can frustrate the customer. A system to handle these exceptions ensures the customer feels heard and their needs addressed.

Cases For Exception Handling

Handing off a package to a customer

Accuracy in delivery: In industries where delivery to the correct address is paramount, such as ecommerce, logistics, and food delivery services, even newly constructed or unreported addresses need to be handled correctly. Exception handling ensures that these addresses are flagged for review rather than rejected and helps prevent frustrated customers.

Regulatory compliance: For businesses like banks, insurance companies, or other institutions with regulatory compliance obligations, having accurate address information is critical. An address that isnt validated because its new or unreported might still be legitimate, and ignoring it could potentially lead to non-compliance with regulations.

Improving customer experience: Address exception handling ensures a smooth customer experience. If a customer provides a valid address that isn't validated due to being new or unreported, they can be frustrated with the process. Address exception handling ensures the business can capture these addresses, improving customer satisfaction.

Enhancing data quality: Address exception handling can improve the overall quality of a businesses address data. Over time, by manually validating new or unreported addresses, companies can fill in the gaps in their database, leading to more comprehensive and accurate address data.

Burning money by not reducing unnecessary costs

Reducing unnecessary costs: Address exception handling can help reduce unnecessary expenses related to undelivered mail or packages, misdirected shipments, or even failed customer communications.

Fraud prevention: Sometimes, an address may be new or unreported due to fraudulent activity. A system to handle these exceptions could allow businesses to detect and investigate potentially fraudulent addresses, providing an additional layer of security.

Implementing Exception Handling

Whether you choose automated processes or manual ones, its essential to have mechanisms to handle exceptions with your address validation system.

Automated Process

An automated exception handling process can quickly approve proposed addresses, keeping track of returns or unsuccessful transactions, thereby preventing delays and maintaining a smooth workflow.

Manual Process

A manual process might involve the customer providing additional information, such as credit card statements or drivers licenses, to prove the validity of the address. This approach ensures that all valid addresses are captured, even if they're new or not reported in the system.

Leveraging Smarty for Exception Handling

Smarty's address validation system is regularly updated with the latest data sources to provide the most accurate results.

Benefits of Smarty's Regular Updates

The regular updates ensure that the system captures as many addresses as possible. However, due to the nature of address data, new addresses may not be immediately available in the system. In some instances, valid addresses may take months or even years to make it into authoritative address databases.

Hybrid Approach to Exception Handling

This is where a hybrid approach comes in handy. You can rely on Smarty for the bulk of your address validation needs, while also maintaining an exception process for addresses that don't match. This way, youre able to serve as many customers as possible, even those with new or unreported addresses.
