6.1.16 Code 39
Symbology number:
8
Valid characters:
“0”..”9”, “A”..”Z”, “-“, “.”, Space, “*”, “$”, “/”,
“+”, “%”
Quiet zone:
left/right: 10X, min. ¼ inch
Module width:
X >= 0.19 mm
Standard print ratio:
1:3:1:3
Ratio format:
1B:2B:1S:2S
Default check digit:
None (eCDNone)
Possible check digits:
Modulo 43 (eCDMod43), Modulo 11
Weight 7 (eCDMod11W7)
Symbol size:
H>=15% of L (H>=6.3 mm!)
H: Height of the barcode without human
readable text
L: width of the barcode
Code 39 is in heavy use in industry, organizations and commerce. It was developed 1974 by
and got standardized by ANSI MH 10.8 M-1983 and MIL-STD-1189.
►
The start-
and stop characters “*” (asterisk) are created automatically and must not be
included in the input data. They are not displayed in the human readable text.
Code 39 is a self-checking code. Code concatenation is possible (if the first encoded character is a
space subsequent barcodes are concatenated by the scanner). Distance-reading is possible (>
1m).
6.1.17 Code 39 Extended
Symbology number:
9
Valid characters:
ASCII-characters between 0..127
Quiet zone:
left/right: 10X, min. ¼ inch
Module width:
X >= 0.19 mm
Standard print ratio:
1:3:1:3
Ratio format:
1B:2B:1S:2S
Default check digit:
None (eCDNone)
Possible check digits:
Modulo 43 (eCDMod43), Modulo 11
Weight 7 (eCDMod11W7)
Symbol size:
H>=15% of L (H>=6.3 mm!)
H: Height of the barcode without human
readable text
L: width of the barcode
Code 39 Extended is rarely used because Code 128 offers much better compression. Code 39
Extended uses the same symbology as Code 39 but encodes also lower-case letters and special
characters („+A“ results in a lower case „a“ when scanned). Scanner must be configured correctly
for decoding Code39 Extended.
