In running text, USA is most often used with the definite article (the USA) as the subject of a sentence. However, it commonly appears WITHOUT the article on addresses, customs forms, shipping labels, product packaging, and website country-selector menus — for example, 'Product of USA' or 'select USA from the list.' In modern English, the abbreviation is usually written without periods (USA), though the older dotted form (U.S.A.) still appears in some formal or traditional contexts.
