On the back of the packaging, tracks are listed in two sections, "!" and "?". Those are also the two sides of the vinyl release.
CD comes in gatefold packaging. Comes with a square four-panel fold-out sheet that has photos of the band recording the album on one side and lyrics/liner notes/credits on the other side. On the shrink-wrap is a hype sticker that says "Switchfoot" in black and "Interrobang" as well as the catalog number in a light off-white color.
In all packaging, the album title and track listing/lyrics are stylized in all lowercase.
