A period (".") is used to delimit the bar code data from the supplemental data.
Data to the right of the "." is supplemental data; data to the left is bar code
data. The two or five digit supplemental can be added to any version of the
UPC/EAN code.
The flag 1 option only applies to EAN 8, EAN 13, and UPC version A. For EAN
13, enabling the flag 1 option prints the first character of the bar code
interpretive. For EAN 8 and UPC version A, enabling the flag 1 option moves
the first and last character of the bar code interpretive outside of the guard
bars.

POSTNET

The Postal Numeric Encoding Technique (POSTNET) uses binary digits,
represented as full bars and half bars, to provide a numeric bar code
symbology that is easily read and decoded by optical reading systems.
POSTNET provides both error detection and correction capabilities.
