Working on a Point of Sale system and trying to understand how to convert a smaller barcode to its longer registered one:
Example is for Coca-Cola Classic, 20 Oz. Bottle whose barcode shows as 04904403 and getting it to its correct UPC 049000000443 (https://www.upcitemdb.com/upc/49000000443)
That is the UPC-E code. You are looking to convert UPC-E code to UPC-A.
See more about Universal Product codes here: https://en.wikipedia.org/wiki/Universal_Product_Code
You can also look at this already answered question: How to convert a UPC-E barcode to a UPC-A barcode?

I am scanning from a barcode reader but it shows every thing like this the string like this when it scans
L008EtZmqQ41daYYVhz000007IU7I#
L00A3RZmqRKOMmp13hy000007IU7I#
But when I use their software the output will be like this which is the actual value which I need it
07117340277500r
Bottom is the barcode image which I scans, Can anyone tell me what kind of the barcode type is this or any other way to decrypt the above mentioned codes into the actual value it would be great help
Looks like its a Code 39 barcode, look if there's some library or something to decode it.

I am currently making an application, with the use of Ionic 3, that can scan GS1-128 barcode format. I tested several barcodes, it worked. But, in GS1-128 format, parenthesis are removed.
I hope there's someone to help. Thank you!
If you mean the parenthesis at the start of the barcode, they are never encoded. They're present in the human-readable part under the barcode so humans can see the AI quickly. But they are not part of the GS1-128 barcode -- unless they're used in the payload after the AI (and that's pretty rare, I've found). What you should be looking for (when you scan the barcode) is the FNC1 code that defines the next characters as an AI. See section 5.4 of the GS1 manual for code128 barcode details, and section 4.15 for the Human readable part. Specifically, rule 3:
Rule 3. Parentheses SHALL surround AIs in HRI [Human readable interpretation] but are not encoded in the GS1 AIDC [automatic identification and data capture] data carrier.
You'll need to look up the AI in a table (there's one in section 3.2) to see how long it should be and if additional data follows (like an expiration date) before you can pull out the actual data.
I have a product multiple items, i want to put barcode on them as it is required to sale them in local markete in Pakistan. For this reason i searched on internet to have solutions and i am still a little confused in it. Note: purpose is to sale my product in a local markete and they tell me to put barcode on it.
Do i really have to register my product with GS1 pk to get barcode
number?
Through internet search i found a software named Really Simple Barcode it make some barcode but not very attractive and also ask me about GS1 barcode number.
There is another mobile app named QuickMart is an excellent app to scan different kind of barcode images and also create QR code for free. but i think that's also not what i need.
What kind of barcode i actually need for selling my product in local
markete? codebar is suitable or not?
Do i need only one barcode image which will b placed on all the itmes
of similar product? or i need to have separate barcode image for every
single item of a single product?
Tell me if there is any way to avoid GS1 registration?
Once i will get my barcode image ready, then how to place it on my
product? any simple and effective method?
Thanks in advance.
Do I really have to register my product with GS1 pk to get barcode number?
Yes. GS1 owns the numbers. Each GS1 office has its own rules but generally you need to join GS1
to obtain the numbers. They issue you with a set of numbers which you allocate to products as you need them. It has to be co-ordinated by a central authority (GS1) - same as car registration.
What kind of barcode do I actually need for selling my product in local markete? Is codebar suitable or not?
EAN/UPC 13-digit product code. Using GS1 Databar is not suitable. All systems in use nowadays world-wide are supposed to be able to read EAN/UPC 13-digit codes. If you produce your codes using any other standard, the equipment at the end-user sales location may not be able to read the code you are using.
Do I need only one barcode image which will b placed on all the itmes of similar product? or i need to have separate barcode image for every single item of a single product?
If you produce a million 400g can of beans in tomato sauce then each one will carry the same barcode number. If you produce 400g can of beans in worcester sauce then each one of those will carry another barcode number - it will be a different number from the barcode printed on your 400g can of beans in tomato sauce as it is a different product. Every 825g can of beans in tomato sauce you produce will carry a third number because it is a different size even if it is the same fundamental product.
Tell me if there is any way to avoid GS1 registration?
You can't avoid GS1 registration in some form. Some administrations will allow a single barcode number or a small set to be issued to a small manufacturer. Best idea is to telephone GS1 ( +92 21 2628213 in Karachi) and ask them. I have heard that they don't bite.
Once i will get my barcode image ready, then how to place it on my product? any simple and effective method?
GS1 can advise - it's their job and mission. Your label manufacturer will be familiar with the routine and can guide. All you need to do is worry about location on your product. Black bars on a white background are best, but other colour combinations are possible (and some are prohibited because the scanner equipment has difficulty reading the code.) GS1 can advise - it's their job and mission (I may have said that before.) GS1 will often want you to provide them with a sample of your proposed label for verification and will normally allow you a number of verifications as part of your membership. Again, they will advise what needs to be changed about your label if it has to be modified for any reason.
If you are producing individual labels using a barcode printer, then printing the barcodes is incorporated into the basic functionality of the printer. From there, it depends on whether you are constructing your labels by using the Printer Control Language for your printer (with which you should be familiar) or whether you are using label-designer software where you can no doubt simply drop a barcode onto your form in the same way as any text or graphic.
Tips: Look a similarly-shaped products already on the market for how to arrange your label. For instance, on small cans with a small circumference (like soft-drink cans,) the bars are probably best rotated so that the code is horizontal.
I know this might be rather a simple issue to ask for and we can also set the barcode format to be scanned by Zxing, like this:
(1)intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); //or any other format
if we do this:
(2)intent.putExtra("SCAN_MODE", "SCAN_MODE"); //for all modes`
While doing the #2 mentioned right above this line, the scanner sometimes seems to scan part of the barcode and picks up wrong information. For example if I try to simply scan a UPC barcode, 98% of the times it works beautifully, but sometimes it just returns me a wrong barcode. I think I know whats happening here, I have an idea up in my head, but what is the exact technical explanation for this? (Anyone familiar with barcodes can help) Thanks in advance guys.
SCAN_MODE is not a valid value. It is ignored and you are scanning for all formats.
It is not reading the wrong information from a barcode; it is finding a 'phantom' barcode among all those white and black lines, of another format. The usual culprit is UPC-E, which is the easiest to accidentally see.
This is why it is far better to restrict the scan to the format you are interested in with a correct value of SCAN_MODE.
I have two barcodes that I am working with. They are clearly different, but both scan as code 128. One is weird and one is normal. I have tried to reprint the data for the barcode in every way I can think of to I can see what subset (A, B or C) is being used.
For the normal one I know it is A for the first 10 chars then it changes the encoding to B.
I cannot seem to find out how to see what the encoding is on the other (weird) one.
I am using a symbol scanner. (I turned on the prefix char but that only told me D (Code 128)
Is there any tool to allow me to dig into the barcode symbologies?
I know very little about barcodes and zero about non-european ones, but for weird implementations of Code 128, there is also GS1-128.
This online barcode generator looks quite nice and can generate a lot of formats you might want to check against.
Chiming in late here, but the ZXing library (I'm a developer) reads Code 128. You could have it scan the barcode while you attach a debugger to the code. It would show you exactly what's happening, step by step, in the decoding, including subset changes.
I know the problem is fixed. But here's some more resource in case someone's in need :)
Like Pekka mentioned, a Code 128 have subsets like Code 128A, Code 128B, Code 128C and GS1-128(UCC/EAN-128). Here is more information on Code 128 barcode, with encoding pattern illustration.
Thanks for those that answered and commented.
Turns out the company that made our barcodes had a printing error. That caused the barcode to look different.
How it ever successfully decoded I do not know. Anyway. I am going to award the question to Pekka because he gave me a workable solution.
