More Data Sources

When it comes to verifying addresses, the quality of your results depends on the quality of the reference sources used – and even though some come close, no one single data source can give you complete address coverage.

Our OptiSource System™ sources the best datasets available from multiple suppliers in one system to give you the very best, utmost accurate results.

Quality datasets mean more accurate results

PAF – Postal Address File

The PAF is Australia’s best file of verified deliverable addresses. It contains every deliverable address point in Australia - currently almost 15 million addresses. It includes not only street addresses but unit information and postal addresses such as PO Boxes.
Compiled and maintained by Australia Post, the PAF was designed primarily to assist them with the delivery of mail. Data is sourced from local, state and territory government land records and Commonwealth government agencies. The quality is extremely high. Data is sourced from local government and then verified by Posties delivering the mail.

GNAF - Geocoded National Address File

The GNAF is Australia’s best file of geocoded addresses. It contains just over 15 million Australian addresses geocoded to different levels of accuracy.
The GNAF data is sourced from Australian state and territory government land records and Commonwealth government agencies. The quality is extremely high.
While the PAF is focused on deliverable addresses, the GNAF contains official addresses and “unofficial” addresses not recognised or recorded by an authoritative body such as a land agency. These include ATMs, tree plantations, reserves and substations.

GNAF Live

GNAF Live provides the most up-to-date geocoded addresses for Australia. It perfectly complements the GNAF and PAF by providing up to date access to Australia’s newest addresses. Addresses are updated daily for the states of ACT, NSW, QLD, WA and NT and weekly for the remaining states SA, TAS and VIC.

PAF – Postal Address File

The PAF is New Zealand’s best file of verified addresses deliverable by New Zealand Post.

NZAD - New Zealand Address Dataset

The NZAD dataset contains all addresses in New Zealand Post’s National Postal Address Database.

LINZ - Land Information New Zealand

The LINZ dataset is New Zealand’s best file of geocoded addresses. The LINZ contains just over 2 million New Zealand addresses geocoded to different levels of accuracy.

This dataset has been sourced from LINZ’s Address Information Management System (AIMS), a centralised database for the management of national addresses, including for electoral purposes.

Frequently asked questions

Do the PAF and GNAF overlap?
Definitely. Approximately 12.5 million address appear in both the PAF and GNAF datasets. The PAF contains almost 2.5 million additional addresses and the GNAF contains just over 2.7 million additional addresses, but these additional addresses differ due to reasons such as timing of notification, verification and type of address included. Between both the PAF and GNAF there is approximately 17.5 million addresses.
So why are there 2.7 million additional GNAF addresses that are not in the PAF?
The primary purpose for the GNAF is to identify for mapping purposes where an address might be. As you’ll see from the examples below, even though the address found in the GNAF is close to the location you might expect the address to be, it’s often not an address that would be considered correct for deliveries which is a prerequisite for it to appear in the PAF.
Examples of additional addresses found in the GNAFCommentsMap and Street views provided by Google Maps
31 COWPER ST, AINSLIE ACT 2602 A public laneway
2 ODDIE PL, CONDER ACT 2906 An unused address for a corner block that is facing the other street. Correct address is:

13 Charterisville Ave
59 ROSEMONT ST S, PUNCHBOWL NSW 2196

61 ROSEMONT ST S, PUNCHBOWL NSW 2196
Both properties have been merged together. Correct addresses are:

59-61 Rosemont St S

Unit 1 59-61 Rosemont St S

Unit 2 59-61 Rosemont St S

Unit 3 59-61 Rosemont St S

Unit 4 59-61 Rosemont St S
And what makes up the 2.5 million additional PAF addresses that are not in the GNAF?
About 80% of these addresses are delivery addresses that only Australia Post and StarTrack can deliver to. These include PO Boxes, GPO Boxes, Locked Bags and Private Bags addresses for letter delivery and Australia Post’s 24/7 Parcel Collection service deliveries. The remaining 20% include additional verified street addresses.
Wouldn’t a merged PAF and GNAF dataset be better?
No. It does however make complete sense to use both sources to get the most comprehensive coverage of Australian addresses. The best way to do that is to verify against the PAF and GNAF datasets separately, prioritising the most up-to-date source. As PAF records are constantly verified for postal deliveries it’s a good idea to verify against the PAF first. If no match is found, then continue to verify against the GNAF.
Why? Let’s use the example of 59 ROSEMONT ST S, PUNCHBOWL NSW 2196 discussed above. If you simply verified this address against the GNAF, or a merged PAF GNAF source the address would come back as correct, which isn’t quite right. It was correct in the past prior to it being merged with its neighbouring lot. If you verified it against the more up-to-date PAF first, the address would be updated to its current form of 59-61 ROSEMONT ST S, PUNCHBOWL NSW 2196, which is the correct address.
What about Google maps as an address data source?

4 Myths about Google Address Validation

You would be hard placed to find someone who hasn’t heard of them. They are a household name around the world and have even become part of our everyday language. I’m sure we’ve all said, “Hang on – I’ll just google it” for example. Whilst they are still the most popular internet search engine on the planet and have some amazing tools, recently they’ve been expanding into the address auto-complete market as a supplier for website forms, so we are often questioned as to why our solutions are better. When talking about the differences between Kleber and Google’s API we often hear about these common myths.

Myth 1. Google data is universal and complete

Because of the rate at which they update their data, Google has some obvious blind spots. Romley Road, Armstrong Creek near Geelong in Victoria is an example of an entire road that can’t be found using Google’s address search (correct at time of writing)

Romley Rd Armstrong

The worldwide coverage presented by Google maps doesn’t necessarily produce good quality addresses either. For example, 9 Hamilton Ave Surfers Paradise is the address for Q1 Tower on the Gold Coast – the tallest building in Australia. Google will find it, but only gives an address for the entire building. However, there are over 550 unique addresses within the building. How will the delivery company know which one of these addresses to leave the parcel with? This problem is replicated across Australia and New Zealand with any office and apartment blocks. Simply finding the building address isn’t detailed enough for deliveries. Kleber uses address data direct from official address sources such as Australia Post, New Zealand Post, Canada Post, Royal Mail, etc. We publish updates and changes to our service every quarter to make sure you have the most up to date records available

Myth 2. Google validates addresses for delivery

Google maps is primarily a geolocation service, designed to plot places on their maps, not designed as an address validator. Ultimately, this means that Google is able to plot locations that are not valid, deliverable addresses. For example, Google maps will happily locate ‘2166 Hamilton Highway Lismore VIC 3324

2166 Hamilton Highway

If you take a quick look though you will quickly see that there are no buildings or infrastructure at all at this “address” so no mail would ever be delivered to it. However, without actually looking each address up individually – how would you know if the address presented is deliverable? Another example – Google “finds” the address 2 Pipeclay St Lawson ACT for us….

2 Pipeclay Street

but it also “finds” 3000 Pipeclay St Lawson ACT in the EXACT same location. Given the length of the small block – this is highly unlikely.

3000 Pipeclay Street

That is because Google tries to provide a relatively good estimation of where an address would be on a map. It cannot tell you what the address is, or more importantly – format it correctly. Kleber will only ever retrieve valid delivery addresses that are formatted correctly

Myth 3. Google is unique in offering auto-suggest results for addresses

Not true. There are many other providers of addressing services where you can begin typing and matching addresses are found. DataTools’ own address validation solutions have been providing this option since 2010 and we’ve been upgrading it constantly ever since. This functionality allows users to search on any part of an address and copes with misspellings and typos (like extra spaces or missing characters). The data returned is verified against delivery point data from official sources such as Australia Post, New Zealand Post, Canada Post, Royal Mail in the UK, etc.

Myth 4. It’s completely free

Depends on your usage and the type of application. It can be free if you have a public site and only need to verify low volumes of addresses. There is a Premium Plan for customers who require an SLA and who expect to process large volumes; each autocomplete API request consumes 0.1 credits. It’s also worth noting that you only get access to technical support when you’re a paying customer. Information correct at time of writing – it could all change. Also – just consider, as a large search engine that is constantly using ‘big data’ to serve up appropriate advertising to its users – what happens with all the information collected via your forms?

Basically, if an accurate, deliverable address is important to the efficiency of your processes then Google will not deliver the goods (excuse the pun).
