The present invention relates to a method and to a device for generatively manufacturing a three-dimensional object (3). A powdery material (11) is applied layerwise onto a support (5) of the device or onto a previously applied layer, and the powdery material (11) is solidified by energetic radiation (8′) at locations corresponding to the object (3). The powdery material (11) is solidified such that a digital, machine readable and three-dimensional coded character is provided at a surface of the object (3).
