Address Lookup tool - what can it do with data? - Fetchify

Address standardisation is the process of removing mistakes and aligning address data with the official format accepted by the postal service of the country in question. 


Postal addresses are a fundamental cornerstone of modern society; connecting individuals with one another, allowing ecommerce and home delivery to flourish, giving residents access to a range of essential services from financial to utilities. Customer address data is also a fundamental cornerstone for modern business, whether capturing data for the first time at checkout or registration, searching or cleansing your existing database. It is vitally important to get the delivery details right, particularly for companies such as ecommerce merchants which ship overseas. If you only have the house number where the recipient country is expecting a postcode, or any number of other simple but easily made mistakes, it could lose you time and money in trying to reformatting for your logistics or courier company, rearranging delivery, potentially returning, and refunding, or even completely losing your goods and the future business of that customer. 


However, although it is a vitally important detail, accurate address data, formatted to the correct standards, is still only a tiny part of your business and the service you provide to your customers, be it in ecommerce, finance, insurance, utilities, hospitality, or a membership organisation. Which brings us to the real answer. 


Quite simply, if you integrate our address auto-complete or postcode lookup address finding tool, you really don’t need to worry about address standardization at all. Our API will analyse the address entered by your customer, detect and remove common errors, match the information to the verified address in our database, apply missing formatting such as capital letters, and populate the address form in the correct order depending on the standards of the selected country. All in a matter of milliseconds. 


For a bit of history, in case you were wondering why we even have set standards for addressing, if I live on the corner of Beech Street and Poplar Avenue, down the road from the train station in my town, why not just say that? Well, the thing is that is exactly what used to happen. Up until the 19th century, people would just describe the place and person they wanted to send the letter to, and the poor postal worker would just have to get as close as they could and then start asking around. At a certain point it just got too exhausting. In the UK, the introduction of house numbers and the division of London into the first districts in the 1850s, began the slow and methodical process of standardizing postal addresses. The Postal Museum in London holds a collection of posters encouraging people to use their correct house numbers and postcodes as many were slow in adopting them, even up to the 1970s when those shown below were produced. 

 

A similar advertising campaign took place in the USA accompanying the implementation of the Zone Improvement Plan (ZIP Codes) in 1963. Having seen the struggle of the American Telephone and Telegraph Company to get the public to adopt area codes at the beginning of phone numbers, the post office pre-empted public resistance and decided to tackle it from the very beginning the with Mr. Zip.


Learning about this can make you realize just how hard the job of being a postman was. Before address standardization the postal round would have been a very different experience. But it’s not all plain sailing these days. You may have seen the story in the news recently about this letter which was successfully delivered against all the odds of eccentric address writing. 


The fact that this letter made it through is a testament to the dedication of the Royal Mail and how lucky we are in the UK. But without the assistance of the referenced BBC2 programme, most likely letters addressed like this will end up at the National Returns Centre in Belfast. Or similar “dead letter” offices in other countries. 


Every country in the world has it’s own story of the development of an addressing system, some more recent than others, and many still being refined. The “Addressing the world—An address for everyone” initiative by the Universal Postal Union seeks to help countries around the world develop cohesive address infrastructures and to guide them through common complications with addressing. But that is probably a subject to dive into another day.


As volumes of mail, mail-order shopping and then ecommerce have increased, so has the need to streamline the sorting and delivery process. Standardised addresses which can be quickly and efficiently recognised and sorted are a vital part of this process. Thankfully over the last 200 years the public has mostly learnt how to use addresses pretty consistently, but people still make mistakes frequently, it happens. Our address search and data validation tools are here to mop up the errors, typos, autocorrects and everything in between, ensuring you collect only accurate and standardised address data, every time.

Guest data captured at the point of booking is quietly falling apart before the stay even begins, and peak season is when it costs the most. A guest books a weekend away for the August bank holiday. Room type, dates, total cost, all confirmed on screen. Then nothing. No confirmation email lands in their inbox. Ten minutes later, they're calling the front desk to check the booking actually went through. Nobody did anything wrong here. The booking engine worked. Payment went through. What broke is quieter than that, and far more common than most hospitality businesses realise. The address you have isn't always the address you think you have A significant share of hotel bookings now arrives through an OTA (an online travel agency, like Booking.com or Expedia) rather than direct. That's not new. What's less well understood is what actually lands in the property management system when they do. Many OTAs pass through a masked or proxy email address rather than the guest's real one, generated specifically for that booking and often expiring shortly after the stay ends. It looks like a valid email address. It behaves like one, right up until the property tries to use it for anything beyond the original booking confirmation. Direct bookings aren't much safer. Industry estimates put the proportion of invalid addresses from manually entered guest data at 20 to 45%, a misspelt domain, a transposed digit, a typo made booking late at night on a small phone screen. None of that shows up as a problem until the moment it matters: a pre-arrival email, a late check-in code, a parking permit, a table reservation confirmation. Why this one email matters more than most Booking confirmations aren't treated like other guest communications, because guests don't treat them like other emails. Open rates for confirmation emails run considerably higher than standard marketing sends, and the expectation isn't "eventually"; it's immediate. A guest expects that confirmation within minutes, not by the end of the day. If it doesn't land straight away, the natural read isn't "it's still processing"; it's "something's gone wrong". A guest who doesn't receive a confirmation doesn't shrug it off. They worry, then they call, then someone on your team spends five minutes confirming something that should have taken none. Peak season is when this compounds None of this is especially visible in a quiet month. A handful of bounced confirmations, a few guests calling to check, easily absorbed. Peak season changes the maths. Higher volumes mean more bad records moving through the system at once, and less staff time available to catch each one before it becomes a guest's problem rather than a data problem. The property that could quietly absorb ten failed confirmations in March is dealing with a hundred in August, right when front desk and reservations teams are already stretched thinnest. Peak season doesn't create this problem. It just makes the one that was already there impossible to ignore. What this actually costs The cost isn't just the phone call. A guest who's already anxious about whether their booking is real arrives in a different frame of mind than one who received a warm, accurate pre-arrival email three days before. Upsell opportunities in that pre-arrival window - an early check-in, a room upgrade, a spa slot, depend on the guest actually receiving it in the first place. None of that happens if the address behind it was never valid to begin with. The fix sits earlier than most teams look The instinct when a confirmation bounce is to fix it after the fact: resend, follow up by phone, apologise. The more useful moment is earlier, verifying email and phone at the point they're captured, whether that's a direct booking form or a reconciliation step against whatever an OTA has actually handed over. In practice, that looks like validation built into the booking form itself: if a guest mistypes their email, the system flags it before they hit submit, the same way a checkout might flag an invalid card number. This is exactly what Fetchify does for hospitality businesses: verifying contact details at the source, so the confirmation, the pre-arrival email, the parking permit, all have somewhere real to land. Caught there, it never becomes a guest-facing problem at all. Getting this right at the point of entry does more than protect a confirmation email. It's a faster, less frustrating booking process for the guest, since a flagged typo takes a second to fix rather than derailing the whole form. It's cleaner data feeding into retargeting and post-stay marketing, since accurate contact details are what make audience targeting worth doing in the first place. And it's a real inbox to send a review request to once the stay is over, rather than one more email quietly bouncing into nothing. If your team is capturing guest contact details manually, or reconciling them from OTA bookings, catching the invalid ones before check-in is more straightforward to fix than it sounds.

What is PAF? The Postcode Address File (PAF®) is Royal Mail’s definitive database of every deliverable address and postcode in the UK. It covers over 32 million delivery points and is updated monthly. If your business relies on accurate address data, at checkout, in your CRM, or for deliveries, PAF is the source that keeps it current. July 2026 in numbers Royal Mail made 54,025 changes to PAF this month. That is not a small number. It represents new homes that need delivering to, businesses that have moved or closed, streets that have been renamed, and addresses that were simply wrong and have now been corrected. Every one of those changes is a record in someone’s database that may now be out of date, and a delivery, a campaign, or a customer communication that could go wrong if the data hasn’t been updated. Delivery point changes at a glance Here’s the full breakdown of what changed, amended, and was removed from PAF in July:

The Address Is Only Half the Journey. Meet nShift. Fetchify ensures the address is correct at checkout. nShift makes sure the parcel gets there. A validated address is a great start, but it's only half the journey. From there, the parcel still has to find the right carrier, the right label, and the right doorstep. That's a different problem, and it's the one nShift solves. What nShift does nShift is a delivery management platform connecting businesses to 1,000+ carriers across 190 countries through a single integration, checkout, delivery options, carrier selection, tracking, and returns, all in one place instead of a separate system per carrier. Customers using nShift see a 20% increase in conversions at checkout and up to 60% fewer "where is my order" queries. Superdry is a good example with 515 stores, 21 websites, and shipping to 100+ countries. As the business scaled internationally, nShift let them onboard new carriers fast and get full visibility across every shipment. As Gordon Knox, Superdry's Business Transformation and Logistics Director, put it, onboarding carriers quickly was essential to a growing international business; that's exactly what they got, plus the data to hold carriers accountable on cost and service. Why we're recommending them Some of nShift's own clients already use Fetchify to validate their checkout data, so we've seen firsthand what good address data unlocks downstream in nShift's platform. That's the real reason for this partnership: the two products solve adjacent halves of the same problem, and we've watched it work in practice. Fetchify validates the address in real time, catching typos, missing flat numbers, and misspelt street or town names as the customer types, without slowing the checkout down, and confirms phone and email are live at the same time. That clean, structured data flows straight into nShift, which picks the right carrier automatically and keeps the customer updated with branded tracking. No reformatting. No manual fixes. No booking failures from bad data. The result: higher conversion, fewer failed deliveries, fewer support tickets, because the two weakest links in the checkout-to-doorstep chain (bad addresses, clunky carrier logistics) are both handled properly. Who this is for Any ecommerce business shipping physical goods stands to benefit, especially if you're juggling multiple carriers, shipping cross-border, or scaling into markets where one carrier doesn't cover it. If delivery reliability has become as much of a pain point as address accuracy, this is worth a look.
