Before you spend money on special fonts or software, you should take a look at one of the best hidden native features of Microsoft Office—creating and printing barcodes. You can print several different kinds of codes from within Word. 1D codes like CODE128, CODE39, UPC A and UPC E, and EAN are available, and the big daddy of 2D barcodes, the. Hats off to you for the thorough research and execution of this UPC-A barcode font. There are quite a few barcode solutions, both softwares and fonts, but most of them for money. If someone has just one product to put on store shelves, he/she has to purchase one of those solutions, install it, just to generate a single barcode. UPC A is the perfect font for all your fun designs. The subfamily is Regular. About the font UPC A. UPC A is free for personal use only. Please, talk with the author for commercial use or for any support. You can use the UPC A to create interesting designs, covers, shop and store name and logos. Techno Bar Code. September 16, 2008.

Manually Creating Barcode Strings for EAN-13 and UPC-A Barcodes
EAN-13 and UPC-A barcodes are widely used to identify retail items.The barcodes encode 13-digit and 12-digit number respectively. At the firstglance, it is easy to create them. Unfortunately if you are using thefont-based solution, it is not that easy as you may think. There area couple of reasons:
To allow space efficiency, the same digit iscoded with different patterns depending on its position in thebarcode.
The same bar/space pattern may have or not have underlyingtext.
At last, font design requires every pattern to berepresented by an unique character. You can not have one characterrepresenting multiple patterns.
As a matter of the complicity, we found that we have to use all printableASCII characters, plus 10 extended characters to represent all bar/space patterns.This character set is far larger than the 10-digit numeric set. For every digit,there are five different encodings:
Left-hand Odd (LO)
Left-hand Even (LE)
Right-hand (R)
Supplement Odd (SO)
Supplement Even (SE)
In addition to the encodings, the unqiue printing requirement adds threevariants to exsiting patterns:
With text below
Without text below

With text above
To allow usereasily derive the encoding, we use a standard US-English keyboard [1] to map patterns to characters.
Figure 1. Character Mapping as laid out on a standard keyboardA. To print left-hand odd encodings without below text, use the first lineof characters on a keyboard:
B. To print left-hand odd encodings with below text, use the second lineof characters - that is, numbers 0-9:
C. To print left-hand even encodings without below text, use the third lineof characters in captial case:
D. To print left-hand even encodings with below text, we still use thethird line of characters, however in lower case:
E. Right-hand encodings do not have even/odd parity. To print right-handencodings, use the fourth line. Captial letters print patterns withoutbelow text: [2]
F. And lower case letters print patterns with underlying text:
G. Supplemental encodings use the last line, with capital letters printingodd encodings:
H. And lower-case letters print even encodings:
I. At last, these text-only symbols are printable with extended characterswith values ranging from
Because all printable ASCII characters are used up, we have to map thesesymbols to extended characters.On systems that a different character set other than
Now that we have introduced character mappings, we proceed to explain howEAN-13 and UPC-A are encoded.
An EAN-13 barcode encodes a 13-digit number. This number has a checkdigit at the end based on modulo 10 algorithm. Using Morovia UPC/EAN/Booklandfonts, a total number of 15 characters are needed to encode the wholebarcode symbol, as depicted below:
Figure 2. Anatomy of an EAN-13 BarcodeThe 16 characters are divided into six parts, as follows:
Leading character, encoded with scheme I;
Start character, represented by open square bracket symbol
Left-hand encodings
Central-guard character, represented by thevirtical bar symbol
Right-hand encodings
Stop character, printable with close square bracketsymbol
The leading character uses mapping scheme I. The charactercorresponding to this pattern is É, character value
The start character follows the leading character immediately.To enter this character, type
The next 6 characters encode the first 7 digits using the left-handencoding scheme. You might wonder how it can be done - here is the trick:the first digit is not converted into any characters; howeverits value determines the parity of next 6 digits. Remember that left-handencodings have two parities - even and odd.

The central guard character is printale using vertical bar
The right-hand encodings do not have parity. Since theyall have text below, scheme F is used. Therefore, the barcode string for
The stop character is mapped to close square bracket
Adding all the parts we derived so far, we get the complete barcode stringfor EAN-13 number
A UPC-A barcode encodes 12 digits with the last digit served as check digit.The UPC-A encoding is very similiar to EAN-13, except the following differences:
Upc-a Barcode Font Excel
UPC-A implies a country prefix
The first digit is converted into bar/space patterns, however, itdoes not have below text. The text is instead placed outside the barcode.
The last digit is also converted into bar/space patterns, however,it does not have below text either and the text is placed at the end ofthe barcode.
A UPC-A barcode string consist of 17 character, and is divided into 6 parts:
Figure 3. Anatomy of a UPC-A BarcodeThe leading character uses mapping scheme I. To print the text-ony symbolfor digit 0, use extended character À (character value 0xc0).
The start character is mapped to open square bracket
This portion actually contains 6 characters, the same as in EAN-13.Since UPC-A numbers have an implicit country code of
The central guard pattern is printable using the vertical barsymbol
The following 6 digits are encoded with right-hand encoding schema.The first 5 digits print their human readable text below and are codedin schema E. However, the last digit does not print text below, so it must becoded with schema F. Therefore, the barcode string for
The last digit of a UPC-A number also has a text form which usesmapping scheme I. Digit 2 is mapped to Â.
The stop character is mapped to close square bracket
