Address Autocomplete (AU)

It is common for customers to browse on websites, add things to their carts, and then abandon those carts forever. There might be several reasons behind it, like high shipping costs, concerns about return policy, window shopping, and lengthy checkouts. The cart abandonment rates faced by Australian businesses are about 76%. Hence, companies should focus on developing their checkout procedures and improving user experience. About 72% of customers shop online for convenience. So, it becomes the responsibility of the company to provide them with that and reduce cart abandonment.

Address Autocomplete

Entering one’s own address may seem easy and quick. But, in reality, many customers find it annoying and time-consuming, and simply skip checkouts owing to this reason. An address autocompletes API can help your customers enter their addresses quickly and accurately.

What Is Address Autocomplete?

Address-autocomplete is a feature that offers type-ahead results on entering addresses. Once a customer starts entering their address, the address autocompletes API can complete it in just a couple of keystrokes. The API presents a list of suggestions, and the customers can choose their addresses from that list.

For instance, if a customer started typing

’53, Mystic Street,’

The API can produce relevant suggestions like below, and so on.

’53, Mystic Street, New Castle, New South Wales 2060,’

’53, Mystic Street, Melbourne, Victoria, 3026,’

This way, the customer won’t have to type in everything, and the address fields will be filled automatically. Furthermore, using PostGrid’s address autocomplete solutions, businesses can complete addresses within seconds, build mailing lists, and conduct direct mail marketing campaigns.

Features of PostGrid's Address Autocomplete API

1. Scalability

It doesn’t matter if you have got one order or a million orders on your website at the same time. PostGrid’s address autocomplete API is scalable and can handle millions of API calls altogether.

2. Address Parsing and Standardisation

Address parsing means breaking down an address into different components, such as the street name, city, and so on. All these components are automatically filled in their respective address fields. Further, addresses are standardised, which means they are formatted as per the destination country’s official address format. Parsing and standardising hundreds and thousands of addresses are very complex jobs, but an address-autocomplete API can handle them just fine.

3. Geolocation

Though the address-autocomplete feature returns address suggestions based on a few keystrokes, these suggestions are not always relevant. The returned addresses might be spread all across the country, and you might have to go through each one of them and make the right choice. In this scenario, geolocation can help you return only the addresses that are close to the users’ IP addresses, hence saving time.

4. Secondary Units

Even Google’s address autocomplete API does not return addresses along with their suite, room, apartment, and floor numbers, but PostGrid’s API does. It considers all the secondary units within a building and fills in the relevant details automatically. Oftentimes, deliveries are failed due to the absence of floor or apartment numbers. Address autocomplete can solve this problem and offer front-door accuracy.

5. Validation

A lot of addresses are not real, valid, or deliverable. Sending mail on such addresses can lead to a loss of time and money. Hence, you need to validate and verify addresses beforehand. PostGrid’s address autocomplete API is AMAS certified and cross-checks all your addresses against the Australia Post database.

6. Test and Live API Keys

Our address autocomplete service can be accessed through the test and live API keys. The test keys allow you to test the API calls before using them in the live environment. You can log in into your account, go to your dashboard, and access these keys. Moreover, PostGrid gives you access to an entire API library, enabling you to use the API keys in your format and language.

7. API Integration

Integrate the address autocomplete API Australia with your CRM to start cleansing your database. The integration enables you to fetch data automatically without having to upload any files anywhere, after which you can autocomplete, parse, standardise, and validate as many addresses as you want. PostGrid’s API can be integrated with various platforms like Shopify, Hubspot, Zoho, Zapier, Magento, and more.

Benefits of Using Address Autocomplete

1. Save Time and Costs

Shipping on unverified and incomplete addresses can result in lost shipments, delays, and a tarnished reputation. Address autocomplete solutions like PostGrid can help businesses save time and money by cutting down manual inputs and speeding up data entry. No need to call up customers and confirm their addresses; the address-autocomplete feature allows you to mail confidently.

2. Increased Conversions

As we discussed above, shopping cart abandonments are very common and hampers conversions. But, if you integrate PostGrid’s address autocomplete API with your website, application, or any online stores, your customers are likely to be induced to complete checkouts. Similarly, the address-autocomplete facet can help you mail to the right addresses while conducting direct mail marketing campaigns, so that you are able to get responses and drive conversions.

3. Narrow down the Address Search

The address-autocomplete feature is like a filter that removes all the spam, irrelevant, and undeliverable addresses and returns the correct ones. It narrows down your address search considerably using geolocation and makes it easier for you to search and complete addresses.

4. Enables Free-Form Searching

Through free-form searching, you can enter any part of the address and get the respective results. For example, instead of starting with the street address, a person might enter the postcode. The address-autocomplete API will then show all the relevant addresses that exist within that area. This way, companies can build new mailing lists and conduct saturated marketing campaigns.

5. High-Quality Results

Addresses returned by an address autocomplete API like PostGrid are complete, parsed, standardised, verified, validated, and absolutely error-free. Hence, once you use the API and cleanse your database, you have unlimited access to high-quality and useful mailing lists. Furthermore, you can update your database every now and then to catch up with any changes.

6. Improved User Experience

Incorporating an address autocomplete API on your store or website can improve its user experience incredibly. Your customers won’t have to type in their entire addresses anymore, and you can deliver their orders on time through those error-free addresses. Type-ahead predictions make shopping fun, time-saving, and convenient, which your customers are likely to appreciate.

PostGrid Vs. Google Places Autocomplete API?

Undoubtedly, Google is the best search engine, but that does not make its address autocomplete API reliable. Although its API is decent and does the basic job, there are several reasons why you should rather use PostGrid’s address autocomplete solutions.

  • Google uses data collected through volunteers, street view vehicles, and crowdsourcing. These sources aren’t reliable due to which the addresses returned by Google’s API can be wrong and invalid. Moreover, their data is not updated regularly. With PostGrid, it is quite the opposite.
  • Google’s pricing structure is expensive, whereas PostGrid is affordable, and its pay-as-you-go pricing makes it perfect for companies of all sizes.
  • Google has no data on internal units like floor and suite numbers, but PostGrid takes care of the same.
  • Google does not correct input errors and proceeds to return addresses based on whatever is typed. PostGrid can correct these errors and return only deliverable addresses.
  • It is simple and speedy to integrate PostGrid’s API with your system, and you can contact the technical team for assistance at any time. Google only offers paid support, plus its API is difficult to integrate.
