Frequently asked questions
How many characters can Code 128 hold?
There is no fixed limit in the symbology, but longer strings produce wider symbols. Keep it to what your scanner window can capture in one pass.
Why is Code 128 preferred over Code 39 in logistics?
It is considerably denser and encodes the full ASCII set, so the same data fits in less label width.
What is GS1-128?
