Real-time address verification checks, corrects, validates, and standardizes postal addresses as soon as users provide them. Besides, bad addresses are the primary reason behind failed deliveries, delays, returns to sender, and costly reshipments. 

It is common for customers to mistype street addresses, provide the wrong postal code, or simply provide an address that doesn’t exist. You cannot compromise your CRM systems, ecommerce platforms, shipping systems, or customer databases by letting bad addresses slip by. 

Businesses with real-time address verification spot these issues proactively before they escalate into operational issues. They can also enrich addresses with geocodes, demographic information, census data, and USPS Residential Delivery Indicator (RDI).

TL;DR

• Real-time address verification prevents bad addresses from disrupting deliveries and onboarding workflows. 
• Businesses can reduce returns, reshipments, and manual corrections with address verification. 
• Fuzzy matching, census data, geocodes, and move-data information enrich addresses. 
• Businesses like ecommerce, finance, insurance, and logistics can collect cleaner data with address autocomplete. 

Key Takeaways 

• Real-time address verification checks postal addresses against authoritative databases at the point of entry. 
• Traditional address verification validates records periodically, not in real-time, leaving scope for invalid addresses to enter databases. 
• Incorrect input, nonexistent addresses, and incomplete information are the primary reasons behind invalid addresses. 
• Geocoding helps businesses extract geographic coordinates to run location-based services and data analytics.

Real-time address verification checks and validates addresses at the point of entry. It flags issues or illegitimate addresses before they enter your database and compromise your operations. For example, real-time address verification stops an ecommerce company from delivering to an invalid or imaginary address. 

It could be a highly useful solution for those businesses that manage high-volume transactions or operate in regions with complicated addressing norms. In contrast, the traditional batch address verification process checks records periodically. They cannot catch issues in real time. Everything is scheduled, and real issues are not detected before they escalate. For this reason, implementing a real-time address verification is a smart decision to: 

• Suggest a corrected decision. 
• Standardize the address 
• Fill in the missing information
• Return additional information

Real-time address verification systems can mark addresses as unreal or invalid. These unreal addresses do not exist and are often fabricated by fraudsters. Incorrect addresses might exist at the same time but are marked for various reasons. In both cases, the address is undeliverable and requires correction. Let’s explore the common reasons behind these scenarios; 

Incorrect Input 

It is possible for users to make mistakes while entering their address. For example, typos in the street address, transposed postal codes, or selecting the wrong state abbreviations. These mistakes will automatically render the address invalid and undeliverable. You might face operational hurdles if you leave them unattended. 

Nonexistent Address 

This is typically done either to commit fraud or just to use the free trial of your services. Real-time address verification can spot and stop these addresses at the point of entry. So, you stop degrading your database with such fake addresses. 

Unoccupied or Vacant 

Businesses cannot use or mail to a vacant address. Real-time address verification helps you confirm if an address is mailable or not. A property may be vacant, under construction, abandoned, or temporarily unoccupied. So, even a real building could be unavailable for delivery. 

Not Registered 

There are two types of addresses under this category: “not registered” and “not yet registered.” US citizens must register their address or apply for an address change every time they move. This means residents must register to receive mail, and USPS can only maintain the records. 

These addresses often include new developments, newly assigned street numbers, or newly created units. For this reason, businesses should consider alternative verification methods or manual review if necessary. 

Not Serviceable 

Some addresses might be “outside the service area,” and USPS cannot deliver mail to these locations. It is a rare scenario, but it could happen, especially with remote or rural addresses. Real-time address verification with geocoding can help a business know about serviceability before approving an address. 

Incomplete Information 

Sometimes, users might not provide the complete address. There could be a missing apartment unit, ZIP code, city, state, or an incomplete street name. Altogether, these missing components will make the address invalid. Real-time address verification with autocomplete capabilities can solve this problem by fetching the missing elements. 

PO Boxes 

A PO Box address isn’t invalid in the first place. In fact, it is a genuine address for mail delivery. However, you cannot rely on them when you need a physical residential or commercial address. So, you can only accept PO Boxes if they fit in the specific workflow. For example, a PO Box address is unreliable for KYC but acceptable for regular mail.

Enhanced Data Quality 

Real-time address verification helps businesses maintain high-quality, accurate data from the point of entry. So, the customer information can be useful in CRMs, shipping systems, analytics databases, and marketing platforms. There’s no need to change it across every system manually. 

Increased Delivery Accuracy 

Invalid, incomplete, or unreal addresses are the primary reasons behind failed deliveries and return-to-sender. Real-time address verification ensures all your mailers and shipments are reaching the intended recipient at the right location. Also, your team can avoid customer service requests and reshipping costs. 

Better Compliance and Risk Management 

Regulated industries like healthcare, finance, and insurance depend on accurate customer information. Real-time address verification helps ensure addresses are accurate and up-to-date to fulfill various compliance obligations. 

Improved Customer Experience 

When customers receive their shipments without issues, they appreciate the experience. Real-time address verification tools play a key role in gathering accurate customer information to keep up with delivery promises without failed deliveries. Besides, embedding autocomplete capabilities into checkout forms further increases convenience and lowers the error rate. It provides typeahead suggestions and autofills address fields from the selected suggestion. 

Superior Location Intelligence 

A postal address can have more use cases than deliveries or identity verification. When you combine addresses with geographic information, you fetch valuable insights. Businesses often use this data for delivery-zone calculations, route planning, service-area analysis, territory management, etc. 

Fraud Prevention

Every business should take critical steps to spot fabricated or unusual addresses to prevent fraudulent activities. These addresses can pose significant financial and security risks to your business. For this reason, you should implement real-time address verification systems to identify addresses that cannot be matched with the official postal databases. It can also save you from scenarios where scammers use different combinations of address elements to fool onboarding systems.

Coding Accuracy Support System (CASS) Certification 

The CASS certification is a USPS program that ensures an address verification software meets its standards of accuracy and efficiency. It means a certified software can match, sort, and correct addresses by relying on the official USPS database.

It is a vital consideration to reduce undeliverable mail and packages. Above all, real-time address verification tools will help you standardize, match, and correct postal addresses, conforming to USPS guidelines. 

NCOA Corrections 

You cannot maintain an accurate database if you forget to periodically update your records. The reality is that databases degrade fast as people move and change their addresses. A reliable real-time address verification tool lets you access the USPS NCOALink database to update your mailing lists. 

A business can process move updates later on, even after capturing an accurate address in the first place. So, there are no headaches of data entry checks and ongoing database maintenance with address autocomplete. 

Geocoding and Reverse Geocoding 

Geocoding data adds another dimension of information to postal addresses. It converts them into longitude and latitude coordinates. So, businesses could run location-based services and data analysis. Reverse geocoding is the exact opposite of this process. It converts geographic coordinates into physical addresses. 

Geocoding offers an additional layer in the address validation process. It confirms that an address actually corresponds to a valid location. After all, businesses need this information to detect fraudulent addresses. 

Fuzzy Matching and Phonetic Algorithms 

These smart algorithms find addresses that are similar, which is necessary for autocomplete capabilities. A real-time address verification tool uses them to manage typos, abbreviations, and variations in address formatting. They work by comparing the pronunciation of address components, then help the users to identify matches. So, they could make the right choice even if they make typographical mistakes. 

Data Enrichment 

Some real-time address verification tools also use third-party sources to provide accuracy and offer additional insights. For example, you can gather demographic, census, or ZIP+4 information for address enrichment. These insights help you better understand new developments, street name changes, and postal code updates.
