Australian Company Stamp Generator (ABN / ACN)
Design an Australian company stamp — the registered name ending in Pty Ltd, the 11-digit ABN written 00 000 000 000, the 9-digit ACN written 000 000 000 and an address with the state abbreviation and 4-digit postcode — for invoices, delivery dockets and forms.

About this seal
Australian law does not require a company to own a stamp. It does require the company's name and its ACN — or an ABN that contains the ACN — on public documents such as invoices, letters and order forms, and a stamp is the quick way to add them to paperwork that wasn't printed with them. The ACN is the 9-digit number ASIC issues when a company is registered; the ABN is the 11-digit number from the Australian Business Register, and for a company it is normally the ACN with two check digits in front. If the business is registered for GST, the same stamp is often used next to a TAX INVOICE heading: a tax invoice has to show the seller's identity and ABN, and GST-registered suppliers must provide one within 28 days when a customer asks for it for a taxable sale over $82.50 including GST. The editor also has trustee (ATF), sole-trader and tax-invoice presets for those variants.
Common uses
- Invoices, quotes and delivery dockets that need the ABN and ACN
- Tax invoices issued by GST-registered businesses
- Bank, supplier-onboarding and customs paperwork
- Forms and letters from overseas counterparties that ask for a company stamp
How to create it
- Open the template — the rectangular stamp layout is pre-applied.
- Replace SAMPLE PTY LTD with the company name exactly as it appears on the ASIC register.
- Enter the ABN (2-3-3-3 digit groups) and the ACN (3-3-3).
- Edit the street, suburb, state abbreviation and postcode, then add a phone number if you want one.
- Export a transparent PNG, SVG or PDF.
Frequently asked questions
Does an Australian company need a company stamp?
No. A stamp is optional. What the Corporations Act requires is the company name and ACN (or an ABN that includes the ACN) on public documents; a stamp is one way of adding them.
What is the difference between an ABN and an ACN?
The ACN is a 9-digit company number issued by ASIC. The ABN is an 11-digit business number from the Australian Business Register used for tax and GST; for a company it is usually the ACN with two leading check digits.
Can I use the stamp on a tax invoice?
Yes, as long as the invoice itself carries the details the ATO lists — the words tax invoice, your identity and ABN, the date, what was sold and the GST. The tax-invoice preset in the editor puts the heading, name, ABN and "Total price includes GST" on one stamp.
Legal & usage
Stamps render in your browser for design and demonstration; nothing you type is uploaded. A stamp adds no legal authority in Australia — the company is bound by authorised signatures. Only show the ABN and ACN of a business you are authorised to act for, and look numbers up on ABN Lookup rather than copying them from old paperwork.
