Answers to Questions

How to decrypt a barcode?

How to create a barcode?

Barcodes are standardized, the generator only follow the instructions of each norm. A barcode is usually made up of a code signaling the beginning, then the data, then a checksum to verify the integrity of the data read, and finally a code signaling the end of the barcode.

How to display a text label under the barcode?

Bar codes are usually accompanied by a text repeating their value for a non-automated reading (by humans). It is possible to write another custom value with dCode.

Preserve the dimensions of the original label for a better rendering.

How to get the country of a product using its barcode?

Products with an EAN-13 code (13 digits) use the first 3 digits to code the country associated with the manufacturer. This is not necessarily the country of production! Here are the first digits for the most often international barcodes:

Example: '000 to 019', '030 to 039' and '060 to 139' for United States

Example: '500 to 509' for United Kingdom

Example: '690 to 699' for China and 489 for Hong Kong
