Yes, we print panel numbers by default on the bottom edge of the wallpaper. For self-adhesive wallpaper, the numbering is placed between the panels on the roll. Once you cut the panels, you can easily see which number belongs to which section.

Non-woven wallpaper
If you order your wallpaper with margin, the numbering will appear within that margin, which you trim off after installation. If you order wallpaper made to the exact size of your wall, you should disable this option to ensure the numbers are not visible once applied.
