What a Product Barcode Really Tells You (and the "Made In" Myth)
Many people believe the first digits of a barcode reveal where a product was made. They don't. Here is what those 13 digits actually encode, and how to use a scan to learn what matters.
Updated October 17, 2026
Almost every packaged product you buy carries a 13-digit barcode, the EAN-13 (now officially the GTIN-13, managed by the non-profit standards body GS1). Social media is full of tips claiming the first three digits reveal a product's country of manufacture. It is one of the most persistent shopping myths. Here is what the numbers really mean.
The anatomy of an EAN-13
| Part | Digits | What it means |
|---|---|---|
| GS1 prefix | First 2–3 | Which national GS1 office issued the number |
| Company prefix | Next several | The brand or company that registered with GS1 |
| Item reference | Following digits | The specific product, size or variant |
| Check digit | Last 1 | A control digit that catches scanning errors |
The myth: "613 means made in Algeria"
The prefix tells you where the company registered its barcode, not where the product was made. GS1 itself states plainly that the prefix does not indicate country of origin. 613 is the range of GS1 Algeria, 611 is Morocco, 619 is Tunisia, and 300–379 is France. But a French brand can manufacture in Poland and keep its French prefix, and an Algerian importer can register a product made elsewhere. For the real origin, read the "Made in" or "Fabriqué en" mention on the pack.
Special prefixes worth knowing
- 978 and 979: books (ISBN) and printed music, whatever the country.
- 020–029 and some 200–299 codes: reserved for in-store use, such as fruit, cheese or meat weighed at the counter. These codes can encode a weight or a price and only mean something inside that shop.
- A leading 0: often a 12-digit American UPC with a zero added in front.
How the check digit catches mistakes
The last digit is calculated from the first twelve. Multiply the digits alternately by 1 and 3, starting from the left, add everything up, and the check digit is whatever brings that total to the next multiple of 10. A scanner that reads one digit wrong gets a total that doesn't match, and rejects the scan instead of showing the wrong product.
What a barcode is actually good for: finding the exact product
A barcode's real superpower is precision. Two moisturisers from the same brand, or the same yoghurt in two sizes, have different codes. That makes it the most reliable way to look up that exact product. Search by name and you might land on the wrong variant; scan the barcode and there is no ambiguity.
That is how Ratee works. Point your camera at the barcode in the shop, and you get that exact product's community score, the star breakdown, and the reviews people found most helpful, for cosmetics and supplements. If it has no reviews yet, you can be the first to rate it or ask the community a question.
Scan a barcode and see what real people think of that exact product.
Frequently asked questions
- Do the first digits of a barcode show the country of origin?
- No. The GS1 prefix shows which national GS1 office issued the number, which is usually where the company registered, not where the product was made. Check the 'Made in' mention on the packaging for the origin.
- What is the barcode prefix for Algeria?
- 613 is the GS1 prefix for Algeria. Morocco uses 611 and Tunisia 619. These prefixes identify the issuing GS1 office, not the country of manufacture.
- Can I scan a barcode to read reviews of a product?
- Yes. With Ratee you scan the barcode with your phone's camera and instantly see the product's community rating and the most helpful reviews.
