The new company has been born out of the £3.8bn merger between Dixons and Carphone Warehouse, which was first announced in May.
The new identity features an interlocked D and C alongside the Dixons Carphone wordmark.
Dixons Carphone has been launched to offer customers what it calls a ‘seamless experience’ and says it aims to take advantage of the internet of things market by offering customers more connected experiences.
It will mean that electrical and mobile products can be sold side by side allowing customers to buy goods like fridges and washing machines that can be controlled by mobile phones.
Seven stores open today and a further 23 will be open by Christmas as the branding begins to roll out. They will operate as store-in-store concessions within existing Currys and PC World Stores.
Dixons operates more than 500 Currys and PC World stores in the UK and Ireland and Carphone Warehouse operates more than 2000 stores across Europe.
A Dixons Carphone spokeswoman says there are no plans to rename any of these stores Dixons Carphone.
