Provided herein is a method for barcoding, comprising: (a) obtaining multiple populations of cells or cell organelles in a plurality of first volumes, wherein: i. within each first volume the cells or cell organelles comprise nucleic acid molecules that are associated with a first subcode of a set of first subcodes, and ii. in different first volumes the nucleic acid molecules are associated with different first subcodes of the set of first subcodes, (b) pooling the cells or cell organelles, (c) separating the pooled cells or cell organelles into a plurality of second volumes, and (d) associating the nucleic acid molecules with a set of second subcodes in the second volumes, wherein a plurality of the second volumes each receive a different second subcode. This method produces at least some nucleic acid molecules that comprise a first subcode and a second subcode.
