The First American Standard is the Universal Product Identifier (UPC). It is a system that uses two alphabets (Alpha and Beta) to represent numerical code values. They may also contain a combination of alphabets or letters (digits).

The Alpha Alphabets is comprised of the first three digits. The value is 10, with a space separating digits one and two. The First UPC is 000-0143-4567. There are four digit alphabets A through Z. The DIGIT COMPONENTAL provides a space between the digits. Digit fifteen represents the country-code for the United States.

The Second American Standard is the Alpha Alphabets plus the letter U (Alpha for the United States and U for Universal), with the last two digits coded as a combination of letters (digits one through four). There are twenty-four digit alphabets available. This is followed by the digit component as a combination of letters A through Z, with a space between the digits. There are sixteen digit alphabets available.

The Next is the Digit Universal Product Code (DIGIT). The only numeric character available is the decimal point (.). This is followed by the alphabets A through Z.

The Digit Universal Product Code is the DIGIT with all digits converted to lower case letters. This combination is followed by the alphabets A through Z and letter U (Alpha for United States) in uppercase.

The Next is the EAN. The number of digits in the EAN can vary from four to twelve. The alpha component has the same digits in both alphabets (A through Z andU).

The next is the digit component followed by the combination of letters A through Z. The alpha component includes the letter U. There are twelve digit alphabets available.

The Third is the Digit Universal Product Code (DIGIT). It has the same digits as the EAN and the alpha component followed by the combination of letters A through Z. The digit component includes the letter U.

The Next is the Digit Component (Digit Universal Product Code followed by Alpha Component) followed by U (Alpha for United States). The digits in the U represent country-code numbers, which in some countries have been designated as Universal Product Identifiers.

The Fourth is the Digit Component followed by the combination of letters A through Z. There are sixteen digit alphabets available.

The Fifth is the Digit Universal Product Code (DIGIT) followed by U (Alpha for United States). The letters in the U represent the country-code numbers, which in some countries have been designated as Universal Product Identifiers.

The Sixth is the Digit Universal Product Code (DIGIT) followed by a country-code number that has been assigned by the International Telecommunication Union (ITU). This code number is identified as the country-code prefix.
