A start character - plus (+).
Encoded value.
Checkdigit required
A stop character - asterisk (*).
Each character consists of up to five bars and four spaces, making nine elements where three out of nine elements are wide The height of the bars must be at least 0.15 times the barcode's length or .25 inches. You must use the greater of the two measurements.
To ensure quality, the width of the inter-character gap should equal the width of the narrowest element (X). The leading and trailing quiet zones must be at least 10 times the length of the narrowest element (X) or .10 inches. You must use the greater of the two measurements.
