The number inside of circle frame 1, 2, ....13..., represents different country which can decree the e-mark certification to others. For example: 1=Germany, 4=Holland, 13=Luxembourg..., etc. Each number means from theirs MOTC (Ministry of transportation and communications) and signed e-mark certification. The approving items of e-mark are:
