The simplest way to identify a barcode type (symbology) is to scan the barcode with the Barcode Decoder Verification App, because it identifies common barcode types and recommends products that generate that barcode type.
A manual method may also be used by examining the start and stop characters in 1D symbols (designated in red) at the beginning and end of the following barcode examples. 2D symbols can be identified by examining their unique patterns.

|Example of Barcode
|The Code 39 barcode is the easiest to use of alpha-numeric barcodes and is designed for character self-checking, thus eliminating the requirement for check character calculations.
|Character set A allows for uppercase characters, punctuation, numbers, and several special functions such as a return or tab.
USS Code 128
ISS Code 128
|Character set B allows for upper and lower case letters, punctuation, numbers, and a few select functions.
|Character set C interleaves two numbers into each barcode character which makes it a very high-density barcode. The FNC1 function (indicated in blue) designates it as a GS1-128 symbol. The number immediately following the FNC1 is the Application Identifier (AI).
