# Best Address Verification Tools - Page 6 *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)* Address verification tools aim to verify, correct, and standardize residential and corporate addresses and other physical identifying data. Businesses use address verification tools to verify mailing lists, customer addresses, and other data that rely on correct mailing addresses. Sales and marketing teams typically find the greatest use out of address verification solutions as the software can check address data acquired by [lead generation software](https://www.g2.com/categories/lead-generation). E-commerce channels also benefit from address verification software by confirming customer shipping addresses are valid. With verified physical addresses, mailing, shipping, and customer location data are more reliable. While tangentially related to [data quality software](https://www.g2.com/categories/data-quality) solutions from a functional standpoint, address verification tools are set apart by its distinct use cases, focus on physical location data, and reliance on authoritative location data sourcing to verify correctness. This leads address verification tools to be distinct products from data quality solutions. To qualify for inclusion in the Address Verification category, a product must: - Automatically check addresses, both incoming and existing, against an authoritative database - Standardize address data to a universal format - Purge or update askew data through fuzzy matching or other corrective processes - Integrate with industry solutions or address databases ## G2 Grid® for Address Verification Tools ![G2 Grid® for Address Verification Tools plotting products by satisfaction and market presence](https://www.g2.com/categories/address-verification/grids.png?focus%5B%5D=166600&focus%5B%5D=68353&focus%5B%5D=115572&focus%5B%5D=101706&focus%5B%5D=1317068&focus%5B%5D=61074&focus%5B%5D=1191159&focus%5B%5D=10483) Highlighted products: PostGrid Address Verification, Smarty, Veriff, Sumsub, Melissa Global Address Verification, Shufti, ComplyCube, and Lob.

Address verification tools, also known as address validation software, help businesses verify, standardize, and parse the customers’ residential and corporate addresses. They can also be used to manage and correct addresses or any physical identifying data collected from different data sources like [lead generation tools](https://www.g2.com/categories/lead-generation) or [customer relationship management (CRM) software](https://www.g2.com/categories/crm). Several address verification APIs can also easily integrate with these tools. These software products have features to ensure that the addresses follow a standardized format, such as the United States Postal Service (USPS) address format. They can automatically check addresses against authoritative databases and integrate with address databases or other software solutions. Some address validation services also offer international address verification, making things easier for e-commerce companies who ship overseas and frequently come across unfamiliar spellings. Address verification systems can also be used to build and maintain a complete profile of customers as they interact with different software solutions like CRM and data generation tools and [databases](https://www.g2.com/categories/database-software). #### What Types of Address Verification Tools Exist? Address verification tools can be broadly classified into two types: batch address verification and real-time address verification. Address verification software products may offer either or both forms of address processing in the same solution. **Batch address verification** As the name suggests, batch address verification software cleans, standardizes, and updates postal addresses in batches. For instance, users can upload a spreadsheet containing hundreds of individual addresses, and the tool will process the same in bulk. **Real-time address verification** With real-time address verification, as soon as the user inputs a business name, postcode, or street address, the tool provides suggestions for autocomplete. This way, the tool ensures that the user inputs only accurate addresses into the system at the point of entry itself. ### What are the Common Features of Address Verification Tools? **Error correction:** Most address verification platforms can perform several types of error correction. This includes correction of spelling errors and switched letters. These tools can also guess missing letters and words and correct the missing or extra spaces. Some products offer the feature to detect and correct abbreviation errors. **Bulk address validation:** This feature allows users to validate location data in bulk, which is especially useful for businesses that deal with hundreds or thousands of customers every day. **Demographic segmentation:** Demographic segmentation is the process of grouping customers based on demographic characteristics like age, gender, and location. With this feature, users can group addresses based on certain criteria. **Non-physical data management:** Some address validation software allows users to manage non-physical address data like phone numbers and email addresses in the same way physical address data can be validated and standardized. **Address autocomplete:** This feature offers automatic suggestions to complete the input address, making it harder to enter incorrect addresses into the system by design. This feature may also exist as an address validation API that completes customer addresses during checkout on e-commerce websites. **Duplicate detection:** This feature saves time by detecting duplicate entries of addresses that are already present in the database. ### What are the Benefits of Address Verification Tools? **Reduce shipping costs and errors:** Incorrect addresses can cause mistaken deliveries, increasing the cost of shipping and mailing. An address data verification solution can prevent such incidents and improve deliverability. **Increase data quality:** Apart from verifying and correcting addresses, address verification tools can increase the address data quality, which in turn can help businesses with better data analysis. For instance, high-quality location data can help users gain accurate information about their customers’ demographics which can be used to improve marketing campaigns. **Enhance customer experience:** Incorrect addresses lead to mistaken deliveries, leading to unhappy customers. This can be avoided by ensuring the addresses are correct, regardless of whether the customer entered an error-free address. ### Who Uses Address Verification Tools? **E-commerce business owners:** E-commerce businesses need to rightly deliver hundreds or even thousands of products on a daily basis. With an address validation tool in place, they can significantly increase the success rate of delivery and enhance customer experience. **Sales and marketing professionals:** To craft the best sales and marketing strategies, businesses will need to understand and analyze their target market. To make sure their analysis is right, the customer data should be accurate. This is where verifying addresses plays a crucial role. ### Software Related to Address Verification Tools Related solutions that can be used together with address verification software include: [Data quality software](https://www.g2.com/categories/data-quality) **:** This type of software product identifies incorrect or incomplete data and offers basic data cleansing functionalities like merge, append, and delete. They come with both manual and automated cleaning options and are primed to establish and maintain high standards for data integrity. [Email verification software](https://www.g2.com/categories/email-verification) **:** Similar to address verification systems, email verification software verifies email lists. This helps businesses ensure they are sending emails to legitimate email addresses. Users can upload and scrub email lists for bad addresses and download cleaned and updated email lists. ### Challenges with Address Verification Software The primary goal of an address correction software solution is to eliminate, or at the very least reduce, the challenges that come with address information. The main challenge is inconsistency. Different countries have different address systems, which makes it all the more necessary and difficult to standardize. Things get even more complicated for the software solution when a state or city doesn’t have an official address system. Another challenge is when the customers aren’t used to the concept of streets and addresses. This is especially true for customers who reside in areas where roads don’t have any set names or numbers. They may use directions or landmarks instead of addresses to let local vendors know where to deliver. E-commerce businesses, especially when shipping internationally, might find this system inconvenient. While some address lookup services can work with very little information, it’s not always the case. ### How to Buy Address Verification Tools #### Requirements Gathering (RFI/RFP) for Address Verification Software Buyers should try to understand the requirements around a number of factors before choosing an address verification platform. They should have a clear understanding of the kind of data quality control features required to make the best use of the solution. Buyers should also decide whether to opt for software products that offer batch processing or real-time processing. This step of understanding what the buyer expects from the software product is called requirements gathering. At this point, buyers should also have a precise understanding of their budget. #### Compare Address Verification Software Products **Create a long list** As an attempt to understand their options, buyers should create a long list of address verification software products. This initial long list can contain any product that meets the basic requirements of the buyer. The goal here is to understand the options available and eliminate products that don’t offer the critical features. **Create a short list** Buyers should then create a shorter list by eliminating products from the long list. This can be performed in a number of ways, including removing costlier options or being more specific with requirements. The usability of the software should be considered as a key factor for creating a short list. In essence, it’s how intuitive the product is to use. It can also be extended to having valuable features like a search bar or a dashboard that’s easy to modify. Buyers can further eliminate products based on their data security features. Since these solutions will be storing customer information, data security is of paramount importance. Buyers can also eliminate products if they lack advanced features like geocoding or based on whether the software stores data on-premise or on the cloud. **Conduct demos** By conducting product demos, buyers can effectively compare their options from the short list. It’s advisable to test the products with the same use cases. During demos, buyers should closely scrutinize the user experience and usability of the product and check whether the product features function as advertised. #### Selection of Address Verification Software **Choose a selection team** Choosing a selection team depends on the use case of the software product. If the software will be used by an e-commerce company to ship out their products to the correct address, then the selection team can include members from customer relationship management, order fulfillment, finance, and the IT department. If the product is aimed to help sales and marketing professionals better market their offerings, then it would make sense to have members from those teams along with relevant stakeholders from the finance and IT departments. **Negotiation** It’s always advisable to have an open conversation with the vendors regarding the requirements. Vendors may offer discounts for multi-year contracts and may also be willing to reduce the price per seat by removing optional features. **Final decision** Before making the final decision on software purchase, buyers can try implementing the address verification product on a small scale. Buyers can choose to verify or standardize a small dataset of their customer addresses and see how the product handles it. Since advanced features like autocomplete or duplicate detection need to be tested several times, it’s ideal to ask the vendor for a free trial. If the user comes across any underdeveloped feature or critical failures, they can take it up with the vendor or go back to the short list to consider other options.
