A process for facsimile coding in which the items of information contained on a two-color original are scanned line-by-line for the purpose of transmission, in which the length of sequences of a first of these colors is represented by first code words consisting of a given first number of binary characters, and the lengths of sequences of the second color are represented by second code words consisting of a second number of binary characters, and in which the first and second code words are followed by third code words when the binary characters are not sufficient for coding the corresponding sequences, provides that the number of binary characters in the third code words is equal to the sum of the number of binary characters of the first code words and the number of the binary characters of the second code words. In a transmitter a coder is provided for the production of the code words, and in a receiver a decoder is provided for decoding the code words. A code word generator is provided in the coder and contains a counter which serves to establish the sequence length of the sequences to be coded and contains a shift register into which the contents of the counter are transferred at stipulated times, in each case after a number of emitted binary characters which is equal to the number of binary characters in the particular transmitted code words and from which the code words are emitted to a transmission unit. A code word decoder is provided in the decoder and contains first and second registers into which the first and second code words are input. The first and second code words being assigned to the sequences with the first and second color respectively, a third register into which the third code words are input, and a transfer switch by way of which the code words are read-out from the first, second or third registers.
