 | Year Stamp: This stamp refers to the date the Smurf mold was created (not the date that specific Smurf was made). |
 | Single Digit: This stamp, one digit long (usually 1-8), refers to the position the mold occupies in the PVC injection machine (it is used to help the manufacturers detect defects). |
 | CE Stamp: European manufacturers must place this stamp on all items to show "minimum compliance with applicable European directives". Until the 1990s, placing a CE Stamp on an item was voluntary (which is why we see it on some 1970s and 1980s Smurfs and not others). |
 | Peyo Stamp: All Smurfs should be stamped "Peyo", a reference to the person who created the Smurfs. Sometimes Peyo is written as a signature, sometimes it is printed in standard text. |
 | Manufacturer Stamp: Smurfs have been made by a variety of companies, who stamp their name on each Smurf they make. The list of stamps include: Applause, Wallace Berrie & Co., Schleich, Bully, Dupuis and Hering. |
 | Country Stamp: The country the Smurf was made in. Generally, the countries are: Germany / West Germany, Hong Kong, China, Sri Lanka, Portugal and Macau. Read about the countries that make Smurfs. |
 | Paint Dot: A colored paint dot representing which country the Smurf was painted in. Paint dots include: Red (Sri Lanka), Yellow (Portugal), Green (Tunisia), Black, White and Blue. Colored dots may also refer to which specific PVC formulation was used. |
 | Muster Stamp: These rare "M" stamps refer to Smurfs who truly "pass muster", and are of the highest quality. A muster Smurf is used as a perfect example for painting other Smurfs of the same mold. Muster is the German word for "sample". |
