A voltage of (nominally) 230 V and a frequency of 50 Hz is used in Europe, most of Africa, most of Asia, much of South America and Australia. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other voltages exist, and some countries may have, for example, 230 V but 60 Hz. This is a concern to travelers, since portable appliances designed for one voltage and frequency combination may not operate with, or may even be destroyed by another. The use of different and incompatible plugs and sockets in different regions and countries provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.

A valid U.S. passport or passport card is preferred, although a birth certificate, naturalization certificate, citizenship certificate, or another document proving U.S. nationality, together with a government-issued photo ID (such as a driver's license) are acceptable to establish identity and nationality. However, the documents required to return to the United States can be more restrictive (for example, a birth certificate and photo ID are insufficient) -- see the section below on Return entry into the U.S.
