The album's title, 'No.6 Collaborations Project', was a nod to Sheeran's previous album, '÷' (Divide), which was released in 2017. The 'No.6' refers to the address of the studio where Sheeran recorded many of the tracks, and 'Collaborations Project' highlighted the album's unique focus on collaborations. Sheeran worked with a range of artists, from hip-hop heavyweights to pop icons, to create a diverse and eclectic album that pushed the boundaries of his music.
