The invention relates to a method for marking an article with an identification pattern which may comprise information relating to the article and/or to the use thereof, including the following steps: defining an alphabet (AT1, AT2) consisting of a plurality of symbols; defining, for each symbol, at least two valid states and at least one invalid state; developing (S1) a reference pattern (P1, P2) including a set of symbols from the above alphabet; developing (S2) at least one representation (P1', P2') of said reference pattern by allocating a specific valid state to each symbol of said reference pattern; and applying (S3) a marking, reproducing said representation of the reference pattern, onto the article.
