Like any other country, Singapore does have a regulatory body that oversees the registration and regulation of companies, corporate service providers and public accountants operating in the country.
Singapore refers to its such a body as the Accounting and Corporate Regulatory Authority (ACRA).
ACRA also facilitates the growth of companies in the country. In line with this mandate, ACRA has a registration process for companies where each company gets a unique number as its identity during the registration process. This process is purely online and done through their online portal, BizFile.
