Pre-approved vs. custom names
The usual company name format in Portugal is “[NAME] – [Business Activity], [Extension]”, but the business activity component is now optional and many newly incorporated companies are dropping it. As regards the extension, a quota company must end its name with Lda and an SA with SA. If the quota company has a single quota holder, then the name must end with “Unipessoal, Lda”.
In the event you do not have a preferred name, a "pre-approved name" will be adopted. This is a fantasy name from a list that is put together and regularly updated by the company registry office, from which anyone can choose a company name that will not be challenged for being confusable. Names on this list cannot be reserved and will be allocated on a first-come, first-served basis. The list is available through this link.
If a specific name is to be adopted, you can either adopt the name(s) of the main shareholder(s) or a fantasy name of your choice. In the latter case you should provide at least 3 alternative names, as the registrar has to ensure that it shall be unique and not confusable with an existing company name. This can be tricky and can be tested here. The name may be any name in any language, but it must in the Roman alphabet and must not be misleading, contain sensitive words, or suggest an activity subject to special authorisation (e.g. financial).
The name of a branch shall be the name of the parent entity followed by the word Sucursal or another Portuguese expression to the same effect.
