A multiresolution optical code can be encoded. A first set of information and a second set of information to encode in an optical code is received. An optical code that encodes the first set of information in a plurality of dots is generated. Each dot of the plurality of dots is divided into a matrix of a first number of sub-dots by a second number of sub-dots, wherein each of the first number and the second number are integers equal to or greater than three and wherein this dividing creates a set of matrices of sub-dots. The second set of information is encoded in a plurality of the sub-dots of the set of matrices of sub-dots.
