What is Address Verification Service (AVS)?

Validate and Verify Postal Addresses for better mail deliverability

Address verification is a process that compares the address with the official USPS database and other trusted sources to ensure that the addresses are valid. A valid address is a must for the delivery of mails to the intended recipient.

Address parsing or correction

The working mechanism behind the address verification service is to check whether the address exists in the database or not. If the address details do not match the database, then, the address verification service rectifies it to match it according to the standard data present in the USPS database. This ensures authenticated and mail-ready data.

Why Is Address Verification Important?

Address Verification Service (AVS) may seem like a perfect way to authenticate the data and make them mail-ready. Still, there is a host of other benefits on offer with address verification. Here are the five reasons why address verification is of utmost importance:

Saves Time

Address verification saves a lot of time, making them an essential tool for your business.

Take this, for example:

You send a package or mail to a prospect. The prospect has mistakenly entered the wrong address, and you ship to the said address. The package is shipped to the wrong address leading to a returned package and undelivered mail.

Such a situation can be frustrating for a company, costing them money and time and affecting the chances of generating leads and turning them into customers. What if you could avail address verification service to authenticate the data at the very first instance? With address validation, you can confirm the address before sending out the package and save time on your hand.

Boost Your Conversion Rate

If you’ve ever been on the side of a customer and tried shopping via the internet, you’ll know how tricky it can get during the checkout process. It’s a prime reason why many users abandon their cart even after adding the products. Adding an address verification service can help you provide your customers with an easy and smooth way to checkout with lesser clicks.

Ensuring the customer has no hassle while checkout will help you endear your brand to the said customer, who may turn out to become one of your long-term stays. Address verification service is a perfect way to increase conversion and generate higher ROI.

Cost-Effective Solution

Remember the example we presented above? Let’s take the same scenario. What if your parcel is returned and you have to re-assign the parcel again with the right address for it to be delivered to the intended user? The entire process will require additional postage, re-assigned personnel, and more, creating a dent in your finance. With the address verification service, the sub-process as this whole can be eradicated, saving you money.

Escalate User Experience

Such has become the time in this internet-savvy modern-day world that even a slight glitch or gimmick in your website can derail your brand image. Creating excellent user interference is a must if you want to uplift your brand image and keep yourself in the back of the customer’s mind. A simple address verification service can work wonders in this case. This can help create an environment of trust in your customers and help you minimize the abandoned carts and bounce rates.

Address verification service smoothes out the entire checkout process, and the shipping, helping escalate the user experience. This can go a long way in nurturing your brand name in the eyes of customers.

To Stand in Line With the Current Times

Take this for a simple example; would you still be happy with a similar shopping experience provided to you that was in the trend 20 years back? The answer would be a straight no. With the advancement in technology, the entire shopping, shipping, and delivery system have evolved quite far.

Being in line with the current trends is one of the significant points to entice customers. You wouldn’t want your customer to think of your company as an outdated one. Adding address verification isn’t merely an optional facility but a need for time. Address verification reduces the total keystrokes needed to complete the checkout process allowing customers an easy and smooth shopping experience.

How Does Address Verification Service Work?

There are two different ways how address verification services work. One of them is to incorporate the address validation API on your company’s website. This can help you by validating and cleansing the data right at the point of entry. The other way is to upload the lists as per the defined formats, i.e., CSV or excel, into the address verification service provider’s website, where they use batch validation and update.

Here’s how the entire process runs:

Features of Address Verification Service

Using the data enhancement feature of the address verification service, you can easily classify the data into different parameters and segment them accordingly as per your need later on. This can help you in creating a targeted campaign for mailing and creating higher chances of lead conversion.
