EAN-13 is 13 digits and used worldwide. UPC-A is 12 digits and used primarily in the US and Canada. EAN-13 codes starting with 0 are equivalent to UPC-A codes. Both are GS1 standards for retail product identification.
For internal use (inventory, assets), yes, you can use any numbers. For retail products that need to scan at stores, you need official GS1 barcodes with a registered company prefix. Self-generated barcodes won't be in any product database.
The check digit is the last digit of EAN and UPC barcodes. It's calculated from the other digits using a mathematical formula. When scanned, the system recalculates the check digit to verify the barcode was read correctly.
For retail products: EAN-13 (international) or UPC-A (US/Canada). For internal inventory with letters and numbers: Code 128. For simple numeric codes: Code 39. For shipping and logistics: Code 128 is most common.
