When to choose this tool
Code 128 is the safest general-purpose choice since it supports letters, numbers, and symbols in one format. EAN-13, EAN-8, and UPC-A are fixed-length numeric formats used specifically at retail checkout, so use those only when the receiving system expects them. Code 39 and ITF-14 are common in logistics and shipping, while Codabar and Pharmacode serve specific industries like libraries and pharma packaging. When in doubt and the receiving scanner is not fixed to a retail standard, Code 128 is the most flexible starting point.
