Determination of illegal status of postal items:

According to the UPU, "an illegal stamp is one that carries the name of a legitimate country or territory but was not produced or printed by the postal administration of that country and is not valid for postage anywhere in the world".

That definition opens the discussion of illegal stamps at the Illegal Stamps website, a valuable resource to which the authors often refer. That website includes lists of known illegal stamps by country name and with images. Basically, for a stamp to be legal, it must be included in a major stamp catalogue or in the WNS stamp system. If not, it is illegal. As part of his work, the Illegal Stamps website author has also referred to UPU IB (International Bureau) Circulars, major stamp selling venues and other web-based sources to determine the status of stamps.

In the websites associated with this page, some illegal stamp images likely have been included without the authors' realizing that they are illegal. Now that we are aware of and sensitive to the problem, we are gradually flagging the illegal stamps entries with the disclaimer "Known illegal issue". To determine when to add the disclaimer, we use the country lists found in the Illegal Stamps website. We will continue the flagging process until we are satisfied that all the illegal stamps in our websites have all been identified. This is a project that may require some years to complete, since it is being done only as we come across those entries while doing our usual website development.
