It doesn’t matter if your business is big or small because customer data is integral to every business. Furthermore, it is painstakingly slow to verify your customer’s information individually.

No one wants to spend hours, days, or even weeks carrying out bulk address validation manually only to find countless errors. So then, what is the solution to this problem? How can you ensure the deliverability of your addresses without spending hours of manual labour on it?

Here we discuss the answer to these questions. Furthermore, we also discuss how you can use Royal Mail address verification to enhance satisfaction and ensure a lasting customer experience.

What Is Batch Address Validation?

As the name implies, batch address validation involves ensuring the validity of addresses in a batch or extensive address database. The validation process requires you to take the address you want to validate and compare it against a verified, reliable, and up-to-date address database.

A business organisation’s address or customer database may contain hundreds, thousands, or even millions of addresses. When it comes to bulk address validation, employing a manual process is not even an option anymore.

A batch address validation service is the only practical way to validate your addresses in bulk. But don’t take our word for it. As we proceed further, we will present you with the benefits of using an address validation service and the different ways you can apply the technology.

Royal Mail Address Database For Batch Address Validation

Suppose you only need to validate a dozen addresses. In that case, you don’t need batch address validation, and you can make do with manual verification. But even with a manual validation process, you still need to find a relevant address database first.

And who better than the biggest postal service provider in the UK – the Royal Mail to get valid and up-to-date address data. Here are some reasons why Royal Mail is the best choice for your business’s Royal Mail address verification process.

The Postcode Address File or PAF

Did you know that the Royal Mail keeps an accurate and up-to-date file on the address data? If the answer is no, then it is high time you familiarise yourself with the Postcode Address File or PAF. It is the official address database of the Royal Mail.

30 Million UK Postal Addresses

The Royal Mail PAF contains a mind-blowing 30 million UK addresses. And yes, this includes every UK residential, commercial, and even PO Box address. PAF is perfect for your company’s bulk address validation as it statistically has the best chance of validating your addresses.

Up-To-Date Address Database

Around 90,000 postal workers postal deliveries to every nook and corner of the UK. Due to this, Royal Mail can update its address database consistently and make changes to it. It results in 3000 to 5000 changes to the address data daily. Hence, it is perfect for Royal Mail address validation.

How Does Batch Address Validation Work?

We know that batch address validation involves verifying the address data of a company by comparing it against a reliable address database. But now it’s time that you learn how the validation process works, including the nifty details.

One thing you should note about address validation is that even small businesses may often deal with large address databases. It means batch address verification is not just for large companies but businesses of all sizes. And the validation process remains the same for small and large companies.

The bulk address verification is not some magical software. It does not instantaneously return deliverable addresses from thin air. A lot is happening behind the neatly arranged verified address data you receive from solutions like PostGrid. Two of the processes that are unavoidable in address validation are

  • Address Parsing
  • Address Standardisation

Address Parsing

The first step in a Royal Mail address validation process is address parsing. Address verification tools like PostGrid breaks up your addresses into their constituent parts. In other words, the address verification software splits each postal address into constituencies such as

  • City
  • Regions
  • Postcode
  • And so on.

Parsing may be an integral part of the bulk address validation process. However, different address verification tools may have different versions of parsing. Hence, address parsing and verification accuracy can also vary depending on your solution.

Address Standardisation

After the parsing process, the addresses go through a standardisation process. The standardisation process further includes a formatting process. It involves aligning the postal addresses in your hand with the standard address format defined by the Royal Mail.

An advanced international address validation tool like PostGrid does something magical in this step. It fills in any missing data and checks for spelling errors or typos. So, if your address is missing a letter or number in the postcode, PostGrid will automatically fill it for you.

Of course, in reality, there is no magic involved in this. It’s all about intelligent programming, but every program has its limitations. In other words, the bulk address verification tool can’t do much if an address does not resemble the PAF data.

Address Verification

It is only after the parsing and standardisation processes that the actual address verification begins. Since the addresses are now in the standard format, it becomes easier for the system to compare them against the PAF.

In other words, you can carry out the bulk address validation process faster with or without an automated system. If the system finds a match for the address in Royal Mail’s PAF, it is a valid address; if not, it is marked undeliverable.

Why Is Batch Address Validation Service Important For Your Business?

If you are a business owner or a marketer, you would naturally want to enhance the effectiveness of your business communication. It may come as a surprise to you. Still, bulk address validation can do more for your business than just validating your address database.
