United States Currency U.S. DollarUSD

Currency Overview

The official currency of the United States is the U.S. Dollar (currency code: USD, symbol: $, often written as US$ to distinguish it from other dollar-denominated currencies). The U.S. Dollar is issued by the country’s central bank, the Federal Reserve System (the Fed), and is one of the most widely used currencies for international trade and travel. Banknotes are printed in a consistent design and are generally easy to recognize worldwide, with a low risk of counterfeiting when obtained from reliable sources such as banks or ATMs.

Denominations

There are six circulating paper denominations: $1, $5, $10, $20, $50, and $100. All share the same size and primary color scheme, and are distinguished by the portrait on the front and the denomination numeral. The $1 features George Washington, $5 Abraham Lincoln, $10 Alexander Hamilton, $20 Andrew Jackson, $50 Ulysses S. Grant, and $100 Benjamin Franklin. Common coin denominations include 1 cent (Penny), 5 cents (Nickel), 10 cents (Dime), and 25 cents (Quarter), with smaller quantities of 50-cent and $1 coins also in circulation. Small bills and coins are often used for tipping, street food, some ethnic restaurants, and small shops, so it’s a good idea to carry some change.

Cash and Payment Habits

Credit cards are widely accepted across the U.S., with Visa, Mastercard, and American Express accepted at nearly all restaurants, malls, hotels, and gas stations. Many retailers also accept mobile payments such as Apple Pay. Cash is typically used for tipping, street vendors, some ethnic restaurants, and smaller shops. ATMs are available at bank branches and inside large supermarkets, with typical withdrawal fees of around $2–$5 per transaction. It’s a good idea to withdraw cash as needed or bring a small amount of U.S. Dollars from home.

A key part of visiting the U.S. is understanding the local tipping culture: it’s customary to leave a tip of 15%–20% at sit-down restaurants, while tipping for baggage handlers, taxi drivers, and leaving money in coffee shop tip jars is optional. Also, the prices displayed on shelves do not include sales tax, which varies by state from 0% to 10%, so the total amount you pay at the register will be slightly more than the marked price.

Tips for Travelers

• A tip of 15%–20% is standard in restaurants, hair salons, and taxis, although some restaurants may include a service charge—always check the bill before paying.
• Shelf prices do not include sales tax, so the final amount you pay will be shown at the checkout.
• U.S. bills are the same size and color regardless of denomination—always check the portrait and number when paying or receiving change.
• The U.S. Dollar exchange rate changes regularly, so check the current rate before you travel. Make sure your international credit card is enabled for overseas use and contactless payments.

United States Overview

The United States (United States of America) is located in the central part of North America, bordered by the Atlantic Ocean to the east, the Pacific Ocean to the west, Canada to the north, and Mexico and the Gulf of Mexico to the south. It also includes Alaska in the northwest corner and Hawaii in the central Pacific. Covering approximately 9.83 million square kilometers, the country consists of 50 states and Washington, D.C. The capital, Washington, D.C., is the seat of the federal government, while New York serves as a global hub for finance and culture.

The U.S. is the world’s largest economy and a highly urbanized immigrant nation, with a population of about 335 million. Immigrants from around the world have shaped its diverse culture. Under its federal system, states vary significantly in laws, taxation, and consumer habits. The tourism industry is highly developed, with well-established infrastructure for everything from theme parks to national parks.

Geography and Climate

The U.S. mainland features a geography where the eastern and western sides are high, and the central region is low: the east has the Appalachian Mountains, the west has the Rocky Mountains, Sierra Nevada, and Coast Ranges, and the central area is a vast Great Plains, with the Mississippi River running north-south and the Great Lakes being the world’s largest group of freshwater lakes. Notable natural wonders include Yellowstone National Park, the Grand Canyon, Niagara Falls (shared with Canada), and California’s Yosemite.

The mainland spans four time zones and has a highly diverse climate: the Northeast has four distinct seasons with cold, snowy winters; California in the West has a Mediterranean climate with dry, sunny summers; the Southwest desert regions experience extremely hot summers; the Southeast along the Gulf of Mexico is humid and rainy, with hurricanes common in summer and fall; Alaska has a subarctic climate, while Hawaii enjoys year-round warmth, making it suitable for travel at any time.

Historical Background

The U.S. was originally inhabited by Indigenous peoples. In the 17th century, Britain established 13 colonies along the East Coast. On July 4, 1776, these 13 states issued the Declaration of Independence, and after winning the Revolutionary War in 1783, the nation was founded. In the 19th century, it expanded its territory significantly through the Louisiana Purchase, westward expansion, and the Mexican-American War. The Civil War from 1861 to 1865 preserved the union and abolished slavery.

In the 20th century, the U.S. rose to superpower status after World War I and World War II. The Apollo moon landing, Silicon Valley’s tech revolution, and Hollywood pop culture have had a profound global impact. The Statue of Liberty in New York, a gift from France to commemorate independence, has become an iconic symbol of American spirit; Times Square is known as “The Crossroads of the World.”

Economy and Currency

The U.S. is the world’s largest economy, with industries spanning finance, technology, entertainment, aerospace, agriculture, and defense. Silicon Valley and Wall Street are global centers of technological innovation and financial capital. The official currency is the U.S. Dollar (USD), issued by the Federal Reserve, and it is the world’s primary reserve and settlement currency. International airfares, hotels, and major purchases are typically priced in USD. Sales tax is usually added at the point of sale, and tipping is deeply ingrained in the culture—travelers should budget for these additional costs.

Culture and Society

American culture is known for its diversity and inclusiveness: Hollywood films, jazz, rock music, Broadway musicals, and sports events like the NBA and Super Bowl are major cultural exports. Each city has its own unique vibe—New York’s fast pace and Broadway, Los Angeles’ sunshine and film industry, San Francisco’s tech and free-spirited atmosphere, and New Orleans’ jazz and French flair all offer distinct appeals.

Cuisine includes hamburgers, hot dogs, barbecue ribs, tacos, and a wide variety of ethnic restaurants. National park culture is deeply rooted, with over 60 parks managed by the National Park Service. Annual free admission days at national parks provide a great opportunity to experience America’s natural beauty.

Tourism Overview

The U.S. is a comprehensive travel destination: iconic sights like the Statue of Liberty, Times Square, and Central Park in New York; the Capitol and Smithsonian museums (most free) in Washington, D.C.; the casinos and shows in Las Vegas; the theme parks in Orlando; California’s Highway 1; the dramatic geology of Yellowstone’s geysers and the Grand Canyon; and Hawaii’s island charm offer a mix of urban shopping, family-friendly attractions, road trips, and nature exploration. Due to the country’s vast size, travel often involves flying or long road trips, so it’s recommended to explore regions in depth rather than trying to cover too much.
