ReportBuilder does not natively support EAN 128 barcodes however it is possible to use the Code 128 setting to manually encode and display these barcodes. We have numerous customers successfully using Code 128 to display EAN 128 barcodes.
1. See the following article on using Code 128 to display EAN 128 barcodes.
2. See the information below posted by another customer on their experiences. The information below refers to the article above.

With regard to point 1, that link takes you to a page which shows the USS Code-128 Character Set. They show Start A as being #203, but in the RB help files in the section on Manually Encoding Data for Code 128, Start A is #208. In fact, for all of these function codes, all the RB Codes are +5 higher than the ones shown on this web page (another page http://grandzebu.net/informatique/codbar-en/code128.htm also uses #203 for Start A). Why are the RB codes different?
With regards to point 2, I have AutoEncode set to False. Sometimes I can set a value to Data and its ok. Othertimes I can set Data to a value and it RB displays an message box with an empty message. So it appears to still be doing some sort of encoding/check anyway. What's going on? I think what is happening is that I was using Character set C which seems to require an even number of numbers. Character Set A seems to be more successful. A nicer error message would have saved me a lot of time.
After several hours of struggling and going by a very torturous route, I finally seem to have been able to print EAN128 barcodes with multiple segments separated by FNC1 by doing something like this:
ppBarcode1.AutoEncode := False; ppBarcode1.Data := #208#207+'01121221'+#207+'17060310'; //#208= Start A, #207=FNC1
It seems to print and scan correctly. One interesting side effect though is that Char Set A is supposed to support uppercase characters only. But when it scans they show in lowercase.
Char Set C does give a much more compressed barcode. If you can use numbers and if you make sure each segment has an even number of digits (it doesn't seem to matter if the overall length is even, each segments seems to need to be even), then you should use Set C like this:
