How Does Fuzzy Address Searching Benefit Your Business and Improve Profitability?

BM predicts that poor-quality data costs US companies $3.1 trillion annually! Appalling, right? 

Businesses often overlook how data fuels their growth and enables them to use their available opportunities in the best way possible!

Consider this- You get various inquiries from many online sources, like contact forms, emails, and more. Your pipeline can be filled with more leads if you organize and use them effectively. But it is a daunting and time-consuming process, keeping you from availing of the benefits. 

physical address vs. mailing address

A fuzzy address searching tool can help you break this chain of data management issues. You may leverage it to make corrections, verify mailing addresses, and segment lists properly!

Let us discuss the meaning of fuzzy address matching and how it benefits companies below! Also, we will cover its use cases and examples to enhance your understanding.

Keep reading below to learn it all!

What is Fuzzy Address Searching?

It is an AI-powered search solution that inputs your address entries and returns all probable results. This service uses fuzzy logic to correct typical data errors, like misspellings, typos, incorrect spacing, phonetic variations, and more.

Let us break it down!

Imagine you have a set of mailing addresses, including these entries:

  • 125 5th Avenue New York City 10006
  • PO Box #125 San Diego
  • 52 NW Kale Street, George

Yes, we know what you are thinking! There can be several reasons that make these addresses invalid or incorrect. They also have many details yet for the users to include. But fuzzy address searching can resolve these problems!

It matches your delivery addresses against the USPS CASS database. If the entry exists in the file, it replaces your record with the updated, correct one. Thus, you get error-free, deliverable mailing lists you can use to ship marketing and other items.

Please note that the fuzzy logic is different from traditional address-matching solutions. These services only check if your record exists in an authoritative database.

Fuzzy address searches are more advanced, spotting and correcting errors in the blink of an eye.

Why Does Your Business Need Fuzzy Address Matching?

Companies need fuzzy address matching to integrate their databases, enhance quality, and facilitate shipping processes. Here are some of the most popular use cases:

Create a Consolidated Customer View

Customers need fast responses from your sales and support teams! For instance, imagine a recurring customer calling your office to ask for a sample product. You can reduce the call time and showcase your efficiency levels by communicating the most updated delivery address and requesting the client to confirm it.

But what would happen if you didn’t have the correct address?

Incorrect details would be communicated, or the client would have to repeat the mailing address (even though they are repeat customers), creating a negative impression.

We have another scenario to help you understand this concept further-

Imagine your sales team wants to draft a tailored pitch to sell a product. They collect all the prospect details from the CRM, but the address has significant data errors. The result?

The fuzzy address matching service lets them send the pitch or proposal to the correct address. It can lead to missed opportunities, delays, and waste, hampering your sales processes.

PostGrid’s address verification services help you leverage fuzzy address searching across all teams. We also assist you in reformatting addresses and referring to the USPS CASS database for quality assurance and accurate shipping.

Enhance Data to Draft Deeper Insights

Making business decisions requires effort, planning, and deep knowledge of the company’s database. A restaurant may want to open a new franchise in another city! Or a SaaS company may plan on tapping into a different market and investing in new models.

Their data decides how they navigate their options and scale their business! But minor issues like duplicate records, incorrect ZIP codes, and non-standardized addresses can hold them back.

A fuzzy address search tool can eliminate this issue for them. Also, they don’t need to spend a fortune or instruct their staff to perform manual tasks to use this solution.

For instance, PostGrid’s address verification API uses fuzzy address matching to let you verify your CRM’s database within minutes with only a few clicks. And voila—you get a cleansed, updated list, enabling you to make quick business decisions based on detailed insights.

Improve Customer Segmentation

Categorizing your customer records allows you to deliver targeted messages and improve operations. It also helps you improve your customer experience and strengthen relationships.

Relationships between customers and companies have a profound impact on every business. It facilitates referrals, repeat orders, loyalty programs, cross-selling efforts, and more!

With nearly 65% of a company’s business coming from repeat customers, paying attention to different ways of improving buyer journeys is vital! 

The fuzzy address search service lets you segment customer lists, personalize communications, and maintain personal connections that go a long way!

Boost Fraud Prevention

Fraud prevention is one of the best use cases of fuzzy address matching tools. You can identify fake orders by validating customers’ addresses at the entry point. Also, you can spot identity theft and other issues more easily using this service than you could without it!

Examples of Real-World Fuzzy Address Searching Use Cases

Almost all industries benefit from fuzzy logic, irrespective of how they collect, store, and use data. Here are some real-world scenarios to shed some light on it:

Healthcare organizations use fuzzy address matching to register new patients. It allows them to store the most updated records, helping them send medical documents and invoices to the correct recipients.

Since HIPAA compliance is of utmost significance in healthcare, this step ensures they don’t mail sensitive information to incorrect addresses. Hence, fuzzy logic helps them comply with the law and avoid data breaches. 

Other use cases of fuzzy matching in healthcare include

  • Data management
  • Targeted marketing
  • Patient record updation
  • Repeat patient management

PostGrid’s address verification API helps many leading healthcare players benefit from fuzzy address matching and ensure accurate postal deliveries.

One of our clients met with us for a quick discussion, and here is how it went: 

Client: “We want to migrate data to a new hospital management software in the upcoming weeks. But most records are incorrect because our staff previously didn’t follow strict data entry regulations.”

Our account specialist: “You can integrate our API into your new HMS with a few steps to start validating every entry in your system. Or you can upload your files in bulk and let PostGrid verify and update them under one request because we can verify 200k addresses simultaneously.” 

We assisted the client in integrating the API into their latest HMS in the upcoming days without their staff having technical expertise. Since we offer a Restful API, they could complete the process using a language of their choice. 

Financial institutions and banks use fuzzy address matching to maintain client records, send compliance letters, and generate fresh leads.

We have met with many company leaders who want to help their sales representatives and marketing executives work with high-quality data. They want to aid their internal functions to reduce friction and reach customers and prospects at their most recent and valid addresses. 

The address-matching service allows financial institutions to maintain consistency across all systems. Any team member can access a client’s correct delivery details within the CRM to improve shipping, communication, and marketing, among other things.

“Insurance companies have a more complex sales process than financial businesses. With hundreds of field visits daily, we wanted our team to take a better approach to address verification so our sales managers spent less time finding clients’ locations. PostGrid helped us reach there because it helped us use fuzzy address searching to its fullest potential.”

This feedback came from one of our old clients, whom we have been working with for a while. The company wanted a simple thing—updated, accurate client addresses at their fingertips daily. 

Our API allowed them to reach their desired efficiency levels by combining geocoding, NCOA cleansing, and bulk verification!

Common Issues Fuzzy Address Matching Can Solve

Fuzzy logic allows you to resolve many data entry errors, like


You can easily modify incorrect spellings to make your mailing lists valid and error-free. USPS uses automated mail sorting machines to read delivery addresses. Hence, this feature can keep your mailers from being rejected or set aside for manual checking. 

Missing or Incorrect Spacing

Minor spacing issues can lead to significant delivery delays and losses. Hence, it is best to use fuzzy address matching to check and correct your mailing addresses beforehand.

Incorrect Street Address Type

USPS needs you to mention the correct street address type in your addresses, like lane, road, driveway, avenue, and more. 

Is it really possible for you to remember and mention so many different types of street addresses?

Fortunately, address matching helps you add the correct street address type without you doing anything!

It uses many advanced features to locate your customers’ mailing addresses and mention the appropriate type.


Abbreviations play a significant role in the USPS delivery infrastructure. Businesses deal with three types of address abbreviations: 

  • Street address types. (ST, RD, AVE, LANE, and more). 
  • Street directionals. (NW, SW, NE, and SE).
  • State abbreviations. (CA, OK, NY, and others). 

PostGrid’s address verification API and software can identify and modify such abbreviations without hassles. The outcome—validated mailing lists that are ready for shipping!
