To navigate to the contents of the Locarno Classification, click on the title of the Classification in the language you prefer (English or French). To see the Classification in PDF format, click on “PDF version” on the upper left-hand corner.


To consult the contents of a class, click on a class number on the lower left-hand area of the screen. To consult the alphabetical list of goods, select the A-Z tab and click on a letter. In the contents area, click on the English/French serial number of an indication of good in the right-hand column to jump to the other language.


To activate the search function, click on Search in the middle left-hand area of the screen. The Search area is displayed on the right-hand side of the screen.

Simply enter a few words into the search field. All indications of goods that contain any of the search words will be shown. Indications of goods that contain more than one search word will be presented separately as “best hits”.

Truncation characters can be used at the beginning or at the end of search words, e.g. *graphic* will obtain search results like “cinematographic”, “geographical”, “photographic” and “topographical”.

The logical AND, OR and NOT operators, along with parentheses, can be used to phrase your search expression, e.g. photographic NOT cameras, photographic OR cinematographic, cameras AND (photographic AND cinematographic). It is also possible to use quotation marks.

It is possible to enter numbers, words or a combination of both in the search field.

A zero must be introduced before a single-digit number, e.g. to search for class 1 use 01.

Do not use full stops or hyphens between numbers of classes and subclasses, eg. to search for class 1, subclass 1, use 0101.
