About UPC-A
UPC-A carries a GTIN-12: a number-system digit, your GS1 company prefix, an item number and a check digit. It is read everywhere, since every EAN scanner treats it as an EAN-13 that starts with 0.
Use a number licensed from GS1 US or GS1 Canada if you sell through retailers. For internal use any 11 digits will scan.
