SINGAPORE - The Accounting and Corporate Regulatory Authority (Acra) has brought a further 1,000 charges against a firmed named Data Register under the Companies Act.

The database firm is being charged with failure to display its company name and registration number in correspondence with other firms in October and November 2013.

These charges are on top of an earlier 104 charges brought against the company in January last year. Each charge carries a maximum fine of $1,000.

Data Register, previously known as Company Register, sent letters asking companies to verify details with it, or risk being deleted from the "Singaporean Company Register" database.

More than 2,000 queries were made regarding letters sent by Data Register between November 2013 and January 2014, Acra said.

Many companies had dealt with Data Register thinking it was a government agency, and assumed they were obliged to provide information.

Under section 144 of the Companies Act, a company must state its name and registration number in business correspondences.
