I am confused by all the names and acronyms. Can you clarify?

Unfortunately there is a lot of obsolete or inaccurate terminology in use.  Here are some pointers to avoid common causes of confusion...

Barcode Number: The number is correctly called Global Trade Item Numbers or GTINs. The same GTIN may be encoded in a variety of different barcodes.

Barcode Symbol: These are the printed symbols in which the numbers are encoded. 

Barcode: The barcode is the number + the symbol

There are several different types or symbologies used in various scanning environments such as retail or distribution.   The most common are....

EAN-13 - used in retail and distribution 

UPC-A - the original American barcode, also used in retail and distribution

(The retail barcodes are sometimes collectively known as EAN.UCC barcodes).

ITF-14 - used only in distribution, cannot be scanned at retail

GS1-128 - used in distribution where additional information such as batch number or use-by date is included with the GTIN in the encoded data.  GS1-128 cannot be scanned at retail.

Download the GS1 New Zealand User Guide for details of correct standards and terminology.

The following terms are incorrect but are in widespread use and cause confusion.  Their origins lie in old GS1 terminology that is now obsolete or in company jargon developed in industry and now entrenched. You should avoid them.

TUN or DUN - incorrectly used for both the numbers and the barcodes on shippers.

APN or EAN - incorrectly used for both numbers and barcodes on retail items and shippers.  Sometimes "EAN" will be incorrectly used to mean a GS1 barcode verification report.

Scans - as in "This barcode scans" or "...doesn't scan," when the person means that the barcode passes or does not pass the GS1 barcode verification test.  A barcode that fails the verification test may still scan ordinarily.
