Wearing the Den Number

The Den Number patch indicates the number assigned to the Den for which a Scout is a member.
All Scouts and Den Leaders wear this emblem as part of the uniform.
The numbers are worn on the right sleeve directly below the American Flag.

Webelos Scouts (and Leaders) whose Den has chosen to use a Patrol Emblem for identification can wear the Patrol Emblem instead.
