Introduction

The ABN Lookup web services allow you to incorporate ABN information and search capabilities into your own applications. There are many uses for the web services, including:

  • ABN validation and pre-fill on forms
  • Keeping ABN details stored in your database up-to-date

The web services provide a number of search options that are not available through the ABN Lookup website. For example, through the web services you can:

  • Request a list of ABNs for a selected postcode with optional filters such as date updated, date registered, etc.
  • Control how many matching names are returned by the name search.
  • Create advanced name search queries to better control search results

Important: We recommend that you avoid using trading names as these have not been updated since 2012 and will be retired on 1 November 2025.
