Code bar code symbology specification Status: Views Read Edit View history. It is used for alphanumeric or numeric-only barcodes. At the end of a string, delaying the transition to code set C until there are an even number of digits remaining avoids an extra symbol.

The Algorithm Design Manual 2nd ed. Code includes symbols: For example, using the patternthe run lengths are 1 digit 11 digit 01 digit 13 digit 02 digit 13 digit 0.

Your basket is empty. Within each code set, some of the data code points are reserved for shifting to one of the other two code sets. Check out our FAQs. The “Code A”, “Code B” and “Code C” symbols cause all future symbols to be interpreted according to the 154177 subcode. Thus, each symbol begins with a bar and ends with a space.


The FNC x codes are used for special purposes. Please download Chrome or Firefox or view our browser tips. The remainder is then converted back to one of the non-delimiter symbols following the instructions given below and appended to the barcode, immediately before the stop symbol. Despite its name, Code does not have distinct symbols, so it cannot represent code points directly. The following table details the widths associated with each bar and space for each symbol.

Take the smart route to manage medical device compliance. If two FNC4s are used consecutively then all following characters will be treated as such, up to the end of the string or another pair of FNC4s. Although code set C uses one code symbol to represent two digits, it does not always produce a more compact code than code sets A or B.


The check symbol is calculated from a weighted sum modulo of all the symbols. The minimum width of the Quiet Zone to the left and right of the Bar Code is 10x, where x is the minimum width of a module. Proof sent to secretariat or FDIS ballot initiated: Code specifies a combination of 6 alternating bars and spaces 3 of each for each symbol.
