"Company stamp" suggests a private limited company, but plenty of sole proprietorships, partnerships and limited liability partnerships use one too — on invoices, receipts, quotations and delivery orders. Every business registered with ACRA has a Unique Entity Number (UEN), and that is all you need for a professional stamp.
Sole proprietorships
A sole proprietorship trades under its registered business name. Put that name exactly as registered along the top of the ring, and your UEN in the centre. Your personal name is optional; most owners leave it off so the stamp represents the business.
Partnerships
A partnership also uses its registered business name and UEN. Because any partner may use the stamp, it is worth agreeing internally who keeps it and which documents it goes on.
Limited liability partnerships (LLPs)
An LLP's registered name ends with "LLP" or "Limited Liability Partnership". Include that ending on the stamp exactly as it appears in your registration, together with the UEN, so documents clearly identify the legal entity.
What to put on the stamp
- Registered name — spelled exactly as on your ACRA business profile.
- UEN — with a label such as "UEN" or "Reg. No.". The generator lets you choose a label or type your own.
- Optional extras — a logo, or a bottom line for a branch or trading location.
Never put personal identification numbers such as an NRIC on a stamp. For the full checklist, see what to put on a company stamp.
Choosing a size
Most businesses choose 22mm, which fits a typical name and UEN comfortably. A longer business name reads better on a larger stamp. Our sizes guide shows how name length affects the choice.
Changed your business name?
If your business converts to a company or changes its registered name, your stamp should change too, because documents must show the correct entity. Design the new version in the free generator and order the physical stamp.
