Artifact Signing Public Trust: Australian sole trader eligibility before paid setup

An Australian sole trader is not automatically confirmed as eligible merely by holding an ABN: Australia is supported for Public Trust organization validation and the workflow accepts an “Organization or a DBA,” but Microsoft’s public documentation does not explicitly state that every Australian sole trader or ABN qualifies as the required legal business entity.^1^

What is officially established

• Country eligibility: Public Trust is available to organizations in Australia. The US/Canada restriction applies to the separate Individual Developer validation route.^1^
• Legal form: The organization workflow is documented for an Organization or a DBA (“doing business as”). However, the documentation does not map Australian legal structures—sole trader, partnership, company—to those categories or identify an ABN as sufficient by itself.
• Azure billing-account type: Organization validation does not require the Azure billing account to have an Organization account type.^1^
• Validation standard: Public Trust requires all identity attributes to be validated under Microsoft’s public-trust certification practices.^2^

Consequently, the definitive eligibility decision depends on whether the validation provider can verify the sole-trader business as a legal business entity from authoritative Australian records.

Evidence and information to prepare

The organization request requires:

1. The legal organization or DBA name.
2. A website belonging to that business.
3. A primary email address on a domain owned by the business.
4. A different secondary address on the same domain.
5. A business identifier.
6. The registered business address.
7. The representative’s first and last names exactly matching government-issued identification.^1^

For an Australian sole trader, the natural candidate for Business Identifier is the ABN, but the published requirements do not explicitly confirm the ABN format or say that an ABN alone is adequate. Prepare authoritative records that consistently connect:

• the ABN;
• the sole trader’s legal name;
• any registered business/trading name;
• the business address;
• the website and email domain.

Public business records should be current before submission. If further evidence is required, the request changes to Action Required, and instructions are sent by email.^1^

Minimum operating history

The current quickstart does not specify a minimum operating period. A newer Microsoft moderator response also states that there are no minimum organization-age restrictions, superseding older preview-era Q&A guidance that referred to three years.^3^

That removes a documented age threshold, but it does not waive the requirement that the business and submitted identity attributes be independently verifiable.

Publisher name

The certificate publisher is derived from the validated identity; it is not freely selectable. Artifact Signing does not allow a custom Common Name (CN) or Organization (O), and the CN must be the legal entity’s validated name.^4^

Therefore:

• A trading name can appear only if Microsoft accepts and validates that name through the Organization/DBA process.
• If the authoritative business evidence identifies the sole trader only by the person’s legal name, that may become the validated publisher identity.
• The public documentation does not guarantee that an Australian registered business name will be used instead of the proprietor’s legal personal name.

During request creation, select Certificate subject preview before submitting. It shows the proposed certificate identity, but final fields come from the completed validation.^1^

Confirm before incurring the setup cost

Submit an Azure support request asking for a written pre-onboarding determination covering:

• whether an Australian sole trader is accepted as an Organization/DBA;
• whether the ABN is the correct business identifier;
• which Australian registration extract is accepted;
• which exact name will populate CN and O.

The Artifact Signing FAQ identifies an Azure portal support ticket as the official support route.^4^ Include no sensitive documents initially; describe the entity type and documents available, then provide evidence only through the support channel Microsoft specifies.
