How to Get a DUNS Number in Australia | 2026

If your foreign company is expanding into Australia, a D-U-N-S Number is one of the less obvious but strategically important registrations you should obtain early. While it is not a legal requirement like ASIC registration or an ABN, a DUNS Number in Australia is often a practical necessity for foreign companies that need to open business credit accounts with Australian suppliers, respond to government tenders, or establish commercial credibility in a market where your parent company’s track record may not be recognised.

This guide explains what a D-U-N-S Number is, why foreign companies operating in Australia need one, the application process, costs, timelines, and how to build an Australian business credit profile from scratch.

What Is a D-U-N-S Number?

A D-U-N-S Number (Data Universal Numbering System) is a unique nine-digit identifier assigned by Dun & Bradstreet (D&B) to individual business entities worldwide. It is the global standard for business identification and is used by commercial credit bureaus, government agencies, and large enterprises to verify and assess businesses.

Every D-U-N-S Number is tied to a single business location. This means your foreign parent company will have its own D-U-N-S Number in its home jurisdiction, and your Australian branch or subsidiary will receive a separate D-U-N-S Number linked to its Australian presence.

Key characteristics of the D-U-N-S Number:

• Unique to each business entity: One number per legal entity per location
• Globally recognised: Used in over 200 countries and by millions of businesses
• Linked to credit reporting: Forms the backbone of Dun & Bradstreet’s commercial credit database
• Non-transferable: The number stays with the entity and cannot be reused or reassigned
• Free to obtain: The basic D-U-N-S Number itself costs nothing to request

In Australia, Dun & Bradstreet operates through its local subsidiary and maintains a comprehensive database of Australian businesses, including registered foreign companies, proprietary companies, trusts, partnerships, and sole traders.

Why Foreign Companies Need a DUNS Number in Australia

While no Australian law mandates a D-U-N-S Number, the practical reality is that many commercial and governmental processes in Australia either require or strongly prefer one. Here are the most common situations where foreign companies find they need a DUNS Number.

Government Procurement and Tenders

Australian federal and state government agencies frequently require a D-U-N-S Number as part of the tender submission process. If your company intends to bid on government contracts — particularly in defence, infrastructure, technology, or professional services — a DUNS Number is effectively mandatory. The Australian Government’s procurement framework, including AusTender, uses business identification numbers to verify suppliers, and a D-U-N-S Number streamlines the registration process.

Supplier Credit Applications

When you establish trade credit relationships with Australian suppliers, distributors, or service providers, many will run a credit check through Dun & Bradstreet before extending payment terms. Without a D-U-N-S Number and an associated credit file, your Australian entity will appear as an unknown quantity, making it difficult to negotiate 30-day or 60-day payment terms. For foreign companies, this is particularly important because your parent company’s credit history in another country does not automatically transfer to your Australian operations.

Banking and Finance

While not always a formal requirement, Australian banks and financial institutions may reference your D-U-N-S Number and D&B credit report during business loan applications, credit facility assessments, or even during the business bank account opening process. Having an established D&B profile adds a layer of commercial credibility.

Enterprise Customer Requirements

Large Australian corporations and multinational companies operating in Australia often require suppliers and partners to provide a D-U-N-S Number during vendor onboarding. This is standard practice in industries such as mining, resources, financial services, and telecommunications, where supply chain due diligence is rigorous.

Apple and Google Developer Accounts

If your company develops mobile applications, Apple and Google both use D-U-N-S Numbers to verify business identity during developer account registration. Your Australian entity will need its own D-U-N-S Number if it will hold the developer account.

DUNS Number vs ABN vs ARBN vs ACN

Foreign companies operating in Australia will accumulate several identification numbers, each serving a different purpose. Understanding how they relate to each other prevents confusion.

Your ABN, ACN, or ARBN is issued during the formal registration process with ASIC and the ATO. The D-U-N-S Number is a separate, private-sector identifier. You need to obtain it independently through Dun & Bradstreet. Having your ASIC registration details and ABN ready will significantly streamline the D-U-N-S application process.

For more information on the ASIC registration process, see our guide to foreign company registration in Australia.

How to Apply for a DUNS Number in Australia

The DUNS number application process is straightforward, but foreign companies should be aware of a few nuances that do not apply to domestic businesses.

Step 1: Confirm Your Entity Structure

Before applying, confirm which Australian entity needs the D-U-N-S Number:

• Registered foreign company (branch): Your ARBN-registered entity will receive its own DUNS Number, separate from the parent company’s number in the home jurisdiction
• Australian subsidiary (Pty Ltd): Your ACN-registered company will receive its own DUNS Number as a distinct legal entity
• Parent company linkage: D&B can link your Australian entity to your parent company’s global D-U-N-S tree, showing the corporate family relationship

If your company has both a branch and a subsidiary in Australia, each will need its own D-U-N-S Number.

Step 2: Check If You Already Have a DUNS Number

Dun & Bradstreet may have already created a record for your Australian entity based on publicly available ASIC data. Before applying for a new number, search the D&B database:

• Visit the Dun & Bradstreet Australia website (dnb.com.au)
• Use the free D-U-N-S Lookup tool
• Search by your company name, ABN, or ACN/ARBN

If a record already exists, you can claim and update it rather than requesting a new number. Duplicate records create confusion and should be avoided.

Step 3: Gather Required Information

To apply for a D-U-N-S Number, you will need:

• Legal business name (as registered with ASIC)
• Trading name (if different from the legal name)
• ABN and ACN or ARBN
• Australian registered office address (physical street address)
• Principal place of business in Australia (if different)
• Phone number with Australian area code
• Name and title of a senior contact person in Australia (director, company secretary, or authorised representative)
• Industry classification (ANZSIC code, or a description of your business activities)
• Number of employees in Australia
• Estimated annual revenue of the Australian operations (or parent company revenue for new entities)
• Year the Australian operations commenced

For a registered foreign company, also have ready:

• Country of incorporation of the parent company
• Parent company’s D-U-N-S Number (if known)
• Details of the local agent appointed under ASIC requirements

Step 4: Submit the Application

You can apply through one of these channels:

Online (recommended): Submit a request through the Dun & Bradstreet Australia website. The online form is the fastest option and typically takes 10-15 minutes to complete.

Phone: Call the D&B Australia customer service line and request a new D-U-N-S Number. A representative will walk you through the information requirements.

Through a registered agent: If you are using a professional services provider for your Australian company registration, they may be able to submit the D-U-N-S application on your behalf as part of their setup package.

Step 5: Verification

After submitting your application, Dun & Bradstreet will verify the information against public records, including the ASIC register and the Australian Business Register. They may contact your nominated representative by phone or email to confirm details. Respond promptly to any verification requests to avoid delays.

Costs and Timelines

Basic D-U-N-S Number: Free

Requesting a standard D-U-N-S Number is free of charge. This is a basic registration that creates a record in the D&B database and assigns your nine-digit identifier.

Processing time: Approximately 30 business days for the free service.

Expedited D-U-N-S Number: Paid

If you need your D-U-N-S Number urgently — for example, to meet a tender deadline or complete a supplier onboarding process — D&B offers expedited processing.

• Express service (5-7 business days): Typically A$300-500
• Priority service (1-3 business days): Typically A$500-800

Pricing varies and is subject to change. Contact D&B Australia directly for current expedited fees.

Ongoing Costs

The D-U-N-S Number itself has no annual renewal fee. However, D&B offers paid products and services that foreign companies often find valuable:

• D&B Credit Report (on your own company): A$50-150 per report. Useful for understanding how suppliers and partners see your credit profile.
• Credit Monitoring: Subscription-based alerts when your credit file changes or when someone runs a credit inquiry on your entity.
• D&B Credit Builder: A paid program that helps businesses proactively build their commercial credit score by reporting positive trade payment data to D&B.

These are optional but worth considering, particularly in the first 12-24 months of Australian operations when you are actively building commercial credibility.

Building an Australian Business Credit Profile

Obtaining a D-U-N-S Number is only the first step. For foreign companies, the real challenge is building a meaningful credit profile in Australia when your entity has no local trading history. A thin or empty credit file can be as problematic as a poor one, because Australian suppliers and partners will simply see an unknown entity.

Establish Trade References Early

Open trade credit accounts with 3-5 Australian suppliers as soon as your operations commence. Even small accounts — office supplies, telecommunications, professional services — contribute to your D&B trade payment history. Pay all invoices on time or early. Consistent, timely payments are the single most important factor in building a positive D&B credit score.

Register with D&B Credit Builder

D&B’s Credit Builder program allows you to submit trade references directly, accelerating the process of building a credit file. This is particularly useful for foreign companies because many smaller Australian suppliers do not automatically report payment data to D&B.

Monitor Your Credit File

Request a copy of your own D&B credit report within 3-6 months of commencing Australian operations. Check for:

• Accuracy of business details (name, address, ABN, industry classification)
• Correct linkage to your parent company’s D-U-N-S family tree
• Any negative data or errors that need to be disputed

Link Your Global Corporate Family

Ask D&B to establish a corporate linkage between your Australian entity and your parent company’s global D-U-N-S Number. This linkage allows credit assessors to see the broader corporate context, which can be particularly beneficial if your parent company has a strong global credit profile. While the Australian entity’s credit will be assessed on its own merits, the corporate family association provides additional context.

Leverage Your Parent Company’s Reputation

In the early months before your Australian credit history is established, you may need to supplement your D&B profile with:

• A letter of support or guarantee from your parent company
• References from international suppliers who can vouch for your payment history
• Audited financial statements of the parent company

These do not replace an Australian credit file, but they bridge the gap while your local track record develops.

Common Challenges for Foreign Companies

Challenge 1: Duplicate Records

D&B may create a preliminary record based on ASIC registration data before you submit your own application. If you then apply without checking, you end up with two records. Always search for existing records first and merge duplicates promptly.

Challenge 2: Thin Credit File

A newly registered foreign company will have no Australian trade payment history. This results in a low or unrated D&B credit score, which can make it difficult to open supplier accounts on favourable terms. The Credit Builder program and proactive trade referencing help address this, but building a solid file typically takes 6-12 months.

Challenge 3: Incorrect Industry Classification

D&B assigns an industry code based on your business description. Foreign companies with diversified operations sometimes receive an incorrect or overly broad classification. Review your industry code after registration and request a correction if needed, as this affects how credit assessors benchmark your business.

Challenge 4: Parent Company Linkage Issues

Establishing the corporate family tree between your Australian entity and the overseas parent can sometimes require manual intervention by D&B. If the linkage is not automatic, contact D&B directly with your parent company’s D-U-N-S Number and request the connection be established.

Challenge 5: Address Verification for Virtual Offices

If your Australian entity uses a virtual office address or registered office service, D&B may flag this during verification. While virtual offices are perfectly legitimate for ASIC registration purposes, D&B prefers to see a physical place of business. Providing additional documentation about your business activities can help resolve any verification queries.

Frequently Asked Questions

Is a D-U-N-S Number mandatory for doing business in Australia?

No, there is no legal requirement to obtain a D-U-N-S Number to operate a business in Australia. However, it is a practical necessity for many commercial activities. Australian government tender processes frequently require one, large enterprise customers often mandate it during vendor onboarding, and Australian suppliers typically use D&B credit reports when deciding whether to extend trade credit. For foreign companies seeking to establish commercial credibility quickly, obtaining a D-U-N-S Number early is strongly recommended.

How long does it take to get a D-U-N-S Number in Australia?

The standard (free) application takes approximately 30 business days to process. If you need the number sooner, Dun & Bradstreet offers expedited services: express processing in 5-7 business days for approximately A$300-500, and priority processing in 1-3 business days for approximately A$500-800. For foreign companies on a tight market entry timeline, expedited processing is usually worth the cost to avoid delays in supplier onboarding or tender submissions.

Can my Australian branch use my parent company’s D-U-N-S Number?

No. Each business entity at each location receives its own unique D-U-N-S Number. Your Australian branch (registered with an ARBN) or subsidiary (registered with an ACN) is a distinct entity from your parent company and will receive a separate nine-digit identifier. However, D&B can link your Australian entity to your parent company’s global corporate family tree, which shows the ownership relationship and provides useful context for credit assessors reviewing your profile.

Does my D-U-N-S Number expire or need renewal?

A D-U-N-S Number does not expire and does not require annual renewal. Once assigned, it remains with your entity permanently. However, you should keep the information associated with your number current. If your Australian entity changes its registered address, key personnel, or business activities, notify D&B so your record remains accurate. Outdated information in your D&B file can create complications during credit checks and vendor onboarding processes.

How do I check my company’s D&B credit score in Australia?

You can purchase a copy of your own D&B credit report through the Dun & Bradstreet Australia website (dnb.com.au). A single report typically costs between A$50 and A$150 depending on the level of detail. The report will show your D&B Rating, payment performance data, any recorded trade experiences, and your corporate family linkage. Reviewing your own report at least once a year is good practice, as it allows you to identify and dispute any errors before they affect your commercial relationships.
