System for sorting sorting pieces into target points logically linked to their target destination, comprising: a) a plurality of target points arranged in an array, wherein the target points are also arranged substantially in a first plane, and wherein one or more target destinations can be logically assigned at least temporarily to each of the target points by means of a sorting controller, b) a plurality of first sorting conveyors (S12, S13) extending in a first direction and having ejection modules (M12a to M12h, M13a to M13h) which can be controlled by the sorting controller and are arranged in a second plane located above the first plane and thereby extending between rows of target points, that the ejection modules (M12a to M12h, M13a to M13h) arranged in the first sorting conveyors (S12, S13) are able to serve target points arranged on both sides of the first sorting conveyors (S12, S13) with sorting pieces provided for these target points, and c) a first pre-sorting conveyor arranged on one side of the array of target points and preferably also in the second plane, with ejection modules (V1b, V1c) which can be controlled by the sorting controller, wherein the first pre-sorting conveyor with its ejection modules (V1b, V1c) can be controlled in such a way that a sorting piece can be transferred to the sorting conveyor of the plurality of first sorting conveyors (S12, S13), which serves the target point provided for this sorting piece, wherein the system comprises a plurality of second sorting conveyors (S21, S22) with ejection modules (M21a to M21h, M22a to M22h) which can be controlled by the sorting controller and which are arranged in the second level located above the first level and thereby extending between rows of target points, that the ejection modules (M21a to M21h, M22a to M22h) arranged in the second sorting conveyors (S21, S22) are able to serve target points arranged on both sides of the second sorting conveyors (S21, S22) with sorting pieces intended for these target points, and the system comprises a second pre-sorting conveyor arranged on one side of the array of target points and preferably also in the second plane, with ejection modules (V2b, V2c) which can be controlled by the sorting controller, wherein the second pre-sorting conveyor arranged on the opposite side of the array of target points is controllable with its ejection modules (V2b, V2c) in such a way that a sorting piece can be transferred to the sorting conveyor of the plurality of second sorting conveyors (S21, S22) which serves the target point provided for this sorting piece, characterized in that the second sorting conveyors (S21, S22) extend from a second direction running at an angle to the first direction. a) a plurality of target points arranged in an array, wherein the target points are also arranged substantially in a first plane, and wherein one or more target destinations can be logically assigned at least temporarily to each of the target points by means of a sorting controller, b) a plurality of first sorting conveyors (S12, S13) extending in a first direction and having ejection modules (M12a to M12h, M13a to M13h) which can be controlled by the sorting controller and are arranged in a second plane located above the first plane and thereby extending between rows of target points, that the ejection modules (M12a to M12h, M13a to M13h) arranged in the first sorting conveyors (S12, S13) are able to serve target points arranged on both sides of the first sorting conveyors (S12, S13) with sorting pieces provided for these target points, and c) a first pre-sorting conveyor arranged on one side of the array of target points and preferably also in the second plane, with ejection modules (V1b, V1c) which can be controlled by the sorting controller, wherein the first pre-sorting conveyor with its ejection modules (V1b, V1c) can be controlled in such a way that a sorting piece can be transferred to the sorting conveyor of the plurality of first sorting conveyors (S12, S13), which serves the target point provided for this sorting piece,
