The rebrand, conducted in partnership with The Pepper Corporation, focuses on the creation of an "official" stamp, which will sit at the heart of the company's main logo, as well as the branding behind its various products including the Official Singles Chart and Official Albums Chart.
The company's trading name will also change slightly, dropping the "UK" that it used to include to simply be known as the Official Charts Company.
Martin Talbot, managing director of the Official Charts Company, said: "The rebranding reflects the consumer research which we conducted earlier this year, which indicated that the 'official' nature of our charts sets us apart from the rest of the field.
"Over the coming months, we will look to reinforce the power of this brand -- and our status as the suppliers of official charts and data for both the music and video businesses."
The Official Charts Company is a joint venture between the British Phonographic Industry and the Entertainment Retailers Association and is responsible for the commissioning, marketing, distribution and management of the UK's industry standard music and video charts.
Its Official Singles Chart is broadcast on BBC Radio 1, MTV and is used by the Commercial Radio Network for the 'Hit 40 UK' show.
