well if their still using the upc‐a symbology, then they are using their own version of barcodes. the rest of the world uses the ean‐13 symbology. it can house one digit more. yay. to be fair - ean-13 and upc‐a is almost the same thing, and upc‐a is fully compatible to ean‐codes.
It's because, like the Internet, the US "did it first". Technically (as Viva Dario noted), if the first digit of an EAN is zero then everything else represents a UPC-A barcode. UPC and EAN share the same basic encoding scheme of bars for each digit, but have different rules regarding why each digit gets what parity.
My fridge looked like that for years and my mother never called me about it. I did have a friend buy me groceries once, though, out of pity. College life is hard.
Yes, it is intentional, and on some barcodes it's actually used to embed an extra digit without needing to add more stripes. For example, on a 6-digit UPC-E barcode, which digits get what parity actually encodes the error-check digit.
They're going to have their work cut out for them once we colonise the solar system. All the thousands of space habitats are going to need ID numbers for the product barcodes made in them.
I stumbled onto your channel today and I’ve been binge watching your videos and find them VERY interesting. Never thought I’d be watching a video explaining bar codes but here I am. 👍🏼
You should really distinguish between a barcode and a UPC (Universal product Code). What you described is a UPC, a type of barcode. There are many types of barcodes which are not UPCs, kind of like the way a square is a rectangle, but not all rectangles are squares. Some can be read from any direction, some can't, some are 2D and hold lots of information. Most types of barcodes do not need to be licensed to be used. I think it's really confusing to most viewers to imply that all barcodes work this way, or are organized in this fashion. There is also the matter of country code 4, which is reserved for "local" use and can be used by anyone without licensing. This is often used for things such as store loyalty cards.
The right hand section isn't just odd numbered it's the inverse bar pattern. So the code for each number is the same, just swap white for black on the opposite side.
To my knowledge dst first came into use in the U.S during WWI and it was mainly to get people inside more as to not waste supplies that could be sent overseas but that’s just what I remember from history class and I could be wrong
Time zones were created to help the railroads spanning The U.S. because noon in California is 4:00 in the afternoon in New York they couldn’t properly coordinate things so the world was broken up into 24 different time zones. Daylight savings time however makes absolutely no sense to me.
@@comradecameron3726 How doesn't it make sense? There is more daylight in summer than in winter, DST moves that daylight to a more convenient time - i.e. a lighter evening instead of bright sunshine at 5 in the morning.
callum9999 you’re absolutely right that there is more light in the summer than in the winter. But it makes no sense to change the time to match. You’re not getting anything more out of it if you change the time on a clock.
You should have explained it better that not every barcode is the same. Just like you have the Baseball "World Series" where only North American teams compete, the American barcode system is called UPC = Universal Product Code. Except that it also only covers small part of the worlds. The actual global system is the EAN = European Article Number which has 13 digits where the UPC has only 12. Then there is the ISBN = International Standard Book Number which has 10 digits which can be converted to an EAN by removing the last digit (the ISBN check digit), adding 978 for "book land" at the beginning and calculating the EAN check digit. ISBN 1408855658 becomes EAN 9781408855652.
Let this be a nice little reminder we’re arguing about how to read barcodes on the internet that nobody even bothers to care to look at except for scanning things and that’s it.
I’m pretty sure you missed out on how the first digit is depicted in the code. There is not just one set of patterns for the left side, there are two. And the order of those digit patterns on the left side „implicates“ the value of the first digit. That‘s why you only need to code twelve digits (95 bars = 3+5+3+7*12) although there are 13 digits in the code (therefore its name EAN-13)
Correct. The example code in the video is actually a UPC-A code with an implied first digit of 0. Which also means that it belongs to US/Canada, and not Switzerland or Egypt.
Nikhil Dabas Correct. And Philadelphia cream cheese is still a brand of Kraft Foods, one of the remaining parts of Kraft that wasn't spun off as Mondelez ( which, by the way, is American-based, just outside of Chicago..not Swiss based).
This isn't for barcodes in general, just for UPC-A codes which are the most common you see in store products. A more compact UPC-E is a smaller barcode is also common with only 6 digits encoded instead of 12. You see them on things like soft drinks and candy bars. These are basically a shorthand for certain 12-digit codes (ones with lots of zeros) and can be converted back into the full 12-digit code.

We have this same concept in TCP/IP network addressing. The network prefix is the leftmost variable-length digits and the host number is the rightmost digits. We use a subnet mask to determine how many digits are the network prefix and the host number.
The register probably just compares the numbers to a master list, similar to a reverse phone directory. The register probably doesn't know what the digits mean, only the product name and a price for that store.
Critiquing, not criticizing. This is only one type of barcode, albeit, the most recognizable. This is EAN-13 (International Article Number). What we typically see in the US is UPC-A, a subset of EAN-13. There are other formats (e.g c128) that aren't regulated by any organization, and that are encoded differently. QR codes are technically a 2d barcode, and encoding is very different. For the codes discussed in the video... The middle 3 bars (the middle guard) is actually 5 bars long.. white, black, white, black, white. The left side of the code is technically 6 digits long, but only has space for 5 characters. The 6th digit is encoded. There are two sets of numbers for the left side (set G and set L). Depending on on what the first digit of the code is, the L/G pattern changes. I.e LLLLL is 0, LGLGLG is a different number, etc... Thus, the black/white pattern for each number isn't always the same on the left side of the barcode. The check digit is normally called the checksum and calculating it is a bit different than described. You add the odd digit positions and multiply by three, add the sum of the even digits to the result of the odd digits, store that number as x, round to the next number divisible by 10 (which l will call y), then calculate y-x. This is your checksum. The right hand side of the barcode isn't necessarily odd white spaces. It's actually the inverse of the L patterns mentioned earlier.. and happens to be odd 😂
I noticed that, for the same digit, that the white spaces on the left are at the same place as the black spaces on the right. Also YOUR VIDEOS ARE AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I learn something new each time.
I immediately tried the check digit verification out on product close at hand, and I couldn't do it. I researched and found out that it's because how you calculated your check digit is wrong... Though, funny enough, it still works for that particular barcode either way. When you said the add the odd digits, you added the second chunk digits together; however, you were supposed to add the odd sequence placement digits: ie, 6+2+1+3+7+6=25. Multiply that by 3 to get 75 then add the even spacing digits: ie, 2+2+0+0+4=8. Take both numbers and add them to get 83. Subtract that from the equal or *higher* value of ten to get your check digit value.
I saw a barcode on a wall on and when I decoded it, it added up to 10. Although I can't be absolutely sure that I have remembered it correctly. I have been meditating very deeply. Visiting the akashic library. My dreams are so vibrant. It means something. This is very helpful. Thank you❤
what i fully understand from those five minutes is that i need to buy a squarespace account, because it just works. not my fault, my brain's barcode is only 1 digit
I work in a meat room at a grocery store and the barcode system there is a lot different than how it works in other places, according to your video. Most of the numbers on the barcode are taken up by the PLU for the meat and the price. Say the barcode is 2 04009 91366 3: The 4009 is the PLU for that particular cut of meat. A small pack of porkchops might be 4010; a chuck eye, 3030. I have no idea what PLU is or what it stands for, but it's the code we put into the computer to tell it what it is we're making a label for. They also exist for produce and some grocery items (especially ones that are difficult to scan, like bags of road salt or ice). I can only assume that the first "0" before the PLU is kept blank in case of a 5-digit PLU, though I could be wrong. The 1366 is the price; in this case, $13.66. I have no idea what the other numbers mean in this system; any insight would be appreciated.
I came here to learn how to read barcodes. All I learned here was about formatting and not actually how to translate the numbers at the bottom of a barcode into the number the barcode scanner reads, which is different.
Amazing video. However at around 4:00 when describing how to calculate the check digit, you stated that the multiple of 10 closest to 73 was 80! Regardless, very informative video. Keep up the good work.
Yeah, all the Swiss stuff I could find within arm's reach are either 761 (all of them but one) or 768 (some medicine). Accordingly, the GS1 code range for Switzerland is 760-769.
Wikipedia is usually a very reliable source. The article in question directly quotes GS1's list. It says the same thing: 622: GS1 Egypt 760 - 769: GS1 Schweiz, Suisse, Svizzera
Actually digit 1 is the use case. It tells you if it's a product, coupon, or local use like member card numbers. Digits 2-6 are the company code for products. Digits 7-11 are the actual product code. Digit 12 is a checksum digit, which is used to validate the UPC.
Two things. If you have a barcode ABCDEFGHIJKL, how does the system know if it's company ABCDEF product GHIJKL as opposed to company ABCDEFGHIJK product L? Also, aren't there 128 combinations of 7 bits, giving 64 left, right pairs to use? Why would one only use 10? It seems wasteful. If it's because 10 is the number of fingers on our hands, then a) that's a stupid reason and b) you can encode 20 digits using a 5 bit encoding and 80 bars

Excel data to bulk barcode labels - To improve work efficiency, you can first enter multiple barcode numbers in MS Excel, then import into our bulk barcode generator software to make barcodes.
At work, I discovered our terminals have various barcode formats installed as system fonts (e.g. each glyph in the font's character set maps to a certain encoding) so I actually set up some formulas into an Excel spreadsheet where I can type in an arbitrary UPC number and get the corresponding UPC barcode. WHICH ACTUALLY SCANS. (This wasn't just a nerd exercise: we have one customer who periodically orders a large number of items at a time, often the same items, so printing out a list of them with scannable barcodes instead of just the UPC numbers saves me the time of actually locating each item to physically scan, or typing in UPC numbers by hand)

I noticed that, for the same digit, that the white spaces on the left are at the same place as the black spaces on the right. Also YOUR VIDEOS ARE AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I learn something new each time.
Also, there have to be odd numbers of black spaces on the left and therefore even numbers of black spaces on the right.

622 code isn't Switzerland. It's Egypt.
Switzerland is 760 to 769
Thought the same, looked at swiss products and none of them even started with a six.
Close enough
Poke777 622 is Egypt but it's actually 62, which is US
Same difference
Anders Lothbrok Philadelphia cream cheese is not made in Egypt
I immediately tried the check digit verification out on product close at hand, and I couldn't do it.
I researched and found out that it's because how you calculated your check digit is wrong... Though, funny enough, it still works for that particular barcode either way.
When you said the add the odd digits, you added the second chunk digits together; however, you were supposed to add the odd sequence placement digits: ie, 6+2+1+3+7+6=25. Multiply that by 3 to get 75 then add the even spacing digits: ie, 2+2+0+0+4=8. Take both numbers and add them to get 83. Subtract that from the equal or *higher* value of ten to get your check digit value.
I was actually trying to find this kind of comment since I calculated 83, though it will still result to the same 12th digit.
I thought the same thing lol. Yeah you're right. Thankss
A lot of things suddenly makes sense to me. I hereby proclaim myself Master Checkout Lord
Actually, the code 622 corrisponds to Egypt! Switzerland has 760-769
I saw a barcode on a wall on and when I decoded it, it added up to 10. Although I can't be absolutely sure that I have remembered it correctly. I have been meditating very deeply. Visiting the akashic library. My dreams are so vibrant. It means something. This is very helpful. Thank you❤
what i fully understand from those five minutes is that i need to buy a squarespace account, because it just works.
not my fault, my brain's barcode is only 1 digit
That transition into the squarespace sponsorship was so good at the end
Got it?
Me: no
Good.
Me: Erm
That transition was so smooth I almost didn't realize it was a sponsor.
I work in a meat room at a grocery store and the barcode system there is a lot different than how it works in other places, according to your video. Most of the numbers on the barcode are taken up by the PLU for the meat and the price.
Say the barcode is 2 04009 91366 3:
The 4009 is the PLU for that particular cut of meat. A small pack of porkchops might be 4010; a chuck eye, 3030. I have no idea what PLU is or what it stands for, but it's the code we put into the computer to tell it what it is we're making a label for. They also exist for produce and some grocery items (especially ones that are difficult to scan, like bags of road salt or ice). I can only assume that the first "0" before the PLU is kept blank in case of a 5-digit PLU, though I could be wrong.
The 1366 is the price; in this case, $13.66.
I have no idea what the other numbers mean in this system; any insight would be appreciated.
Very smooth ad transition
So what does this have to do with planes?
idk
barcodes are on plane parts
When you go to your local airplane dealer, each plane has a barcode too.
Seems more like an ad for squarespace than anything
boarding pass? XDD
I came here to learn how to read barcodes. All I learned here was about formatting and not actually how to translate the numbers at the bottom of a barcode into the number the barcode scanner reads, which is different.
Every time I watch some old random Sam's video I get amazed how he improved as a narrator. Fantastic
I thought the math problem to get the 12th number was one of your wonderful internet jokes... it wasn’t... I still lol’d
Amazing video. However at around 4:00 when describing how to calculate the check digit, you stated that the multiple of 10 closest to 73 was 80! Regardless, very informative video. Keep up the good work.
I think he ment the next multiple of ten, otherwise the check digit would be negative
Thank you I can finally read Agent 47's barcode.
So what does it say?

Where the planes at?

Where'd the white planes at?
Like Bradley Irving said "around the lower atmosphere"
2:04 But "622" is Egypt according to the GS1 country code list at en.wikipedia.org/wiki/List_of_GS1_country_codes
Yeah, all the Swiss stuff I could find within arm's reach are either 761 (all of them but one) or 768 (some medicine). Accordingly, the GS1 code range for Switzerland is 760-769.
I'm always suspect of wiki "facts" looks to me he checked GS1's list
Wikipedia is usually a very reliable source.
The article in question directly quotes GS1's list. It says the same thing:
622: GS1 Egypt
760 - 769: GS1 Schweiz, Suisse, Svizzera
I don't want Google+ I pity you
Actually digit 1 is the use case. It tells you if it's a product, coupon, or local use like member card numbers.
Digits 2-6 are the company code for products.
Digits 7-11 are the actual product code.
Digit 12 is a checksum digit, which is used to validate the UPC.
Two things. If you have a barcode ABCDEFGHIJKL, how does the system know if it's company ABCDEF product GHIJKL as opposed to company ABCDEFGHIJK product L? Also, aren't there 128 combinations of 7 bits, giving 64 left, right pairs to use? Why would one only use 10? It seems wasteful. If it's because 10 is the number of fingers on our hands, then a) that's a stupid reason and b) you can encode 20 digits using a 5 bit encoding and 80 bars

i never knew how barcodes work all i knew was "they scan them and they know what it is"
I learned something about the complexity of the system AND why it works worldwide...for me it was worth 5 minutes of my life to listen...spend an hour a day getting news & random bits of knowledge...I might or might not ever use...
it’s crazy that there’s so much thought put into something as normal as a barcode and the people doing it are making big time money from it
2:43 When the 0 is greyed out, the bar that dips down next to it has a few pixels covered by the box. That is the very definition of r/mildlyinfuriating.

Okay I just took the nearest product from me and the barcode ends with ">" WTF
According to wikipedia, the country with GS1 country code 622 is Egypt not Switzerland.

@Waldo, did you read that on Facebook?
How dose the barcode work when you by things free weigt? dose the store simply have millions of barcodes on hand with set priceses individualy for each gram you buy?
You said the formula is (odd x 3) + evens then subtract that from the nearest tens... but on screen you showed just doing the last 5 digits x 3 plus the first 6 digits... and still got the right answer.
they use number 6 to divide the parts, its 666 the devil mark!

Excel data to bulk barcode labels - To improve work efficiency, you can first enter multiple barcode numbers in MS Excel, then import into our bulk barcode generator software to make barcodes.

Yup!

At work, I discovered our terminals have various barcode formats installed as system fonts (e.g. each glyph in the font's character set maps to a certain encoding) so I actually set up some formulas into an Excel spreadsheet where I can type in an arbitrary UPC number and get the corresponding UPC barcode. WHICH ACTUALLY SCANS.
(This wasn't just a nerd exercise: we have one customer who periodically orders a large number of items at a time, often the same items, so printing out a list of them with scannable barcodes instead of just the UPC numbers saves me the time of actually locating each item to physically scan, or typing in UPC numbers by hand)
Very interesting. I've done work involving barcode scanning, and have recently been given a scanner. I'm going to be checking stuff out now.
