Have you ever looked at the black and white stripes on barcode labels and wondered how on earth they match up to the numbers showing at the bottom? The twelve numbers can seem wholly unrelated to the strings of black and white above, but there is indeed a way to ‘read’ barcodes, provided you know what you’re looking for.

The first thing to note is that 12-digit barcodes are split into two equal halves, with six on each side. This divide is signalled by longer strips down the middle which reach further than the others in the barcode. There are also these long strips at both sides of the barcode, to signal the start and end. It is the stripes contained within these which signify the numbers.

Secondly, it is important to note that it is not just the black lines which have meaning, the white ones do too. These also make up part of the code, with spaces and thicknesses determining the numbers.

So, how then, do you work out what each number is? Well, each number relates to a space on the barcode of seven individual linear segments. The thinnest lines of the barcode will just take up one of these segments, whilst the thickest lines can take up to four. Once you have located where each segment is, you can begin decoding.

Each number relates to a predetermined code, with 1, for example, being recognised with a pattern of 2221. This means that there will be, in a segment, a black line with a thickness of 2, a white line with a thickness of 2, a black line with a thickness of 2 then a white line with a thickness of one.

Each number from 0-9 has its own unique code. These are: 0 = 3211, 1 = 2211, 2 = 2122, 3 = 1411, 4 = 1132, 5 = 1231, 6 = 1114, 7 = 1312, 8 = 1213 and 9 = 3122. As you can see, all ten of these are unique but all the numbers for each segment add up to seven.

Once you’ve remembered the individual codes and mastered the art of differentiating between the segments of 7, you will be able to proficiently work out the numbers on a barcode, perfect, for a dinner party trick.
