A charity label is a label resembling a postage stamp, sold by charities to raise funds.
[1] They are generally intended to be used on mail, as a way of advertising the sender's support of the charity's cause.
While designed to look like postage stamps, they only rarely include a denomination, and never the name of a country.
They are distinct from charity stamps which also include a charge for postage.
Charity labels are one of several kinds of cinderella stamp.
