The company will be registered with ACRA. Being registered means the company has named directors, shareholders, an address and a bank account.
You can search ACRA’s database to verify a company’s registration. Simply type the company’s name into the database. If they are legitimate, the company will appear there.
If the company doesn’t appear there, warning bells should ring. Of course, it may be a misunderstanding or misspelling, so always double check. But if the company doesn’t appear on ACRA’s database, they are not legally operating.
