Area Codes -- The area code for northern Arizona is 928 and for southern Utah it's 435.
Business Hours -- Business hours vary depending on the season, but are generally 9am to 6pm.
Doctors -- Check with your hotel staff for help identifying local doctors.
Drinking Laws -- The legal age for purchase and consumption of alcoholic beverages is 21; proof of age is required and often requested at bars, nightclubs, and restaurants, so it's always a good idea to bring ID when you go out. Do not carry open containers of alcohol in your car or any public area that isn't zoned for alcohol consumption. The police can fine you on the spot. Don't even think about driving while intoxicated.
Electricity -- Like Canada, the United States uses 110 to 120 volts AC (60 cycles), compared to 220 to 240 volts AC (50 cycles) in most of Europe, Australia, and New Zealand. Downward converters that change 220-240 volts to 110-120 volts are difficult to find in the United States, so bring one with you.
Embassies & Consulates -- All embassies are in the nation's capital, Washington, D.C. Some consulates are in major U.S. cities, and most nations have a mission to the United Nations in New York City. If your country isn't listed below, call for directory information in Washington, D.C. (tel. 202/555-1212) or check www.embassy.org/embassies.

Emergencies -- Dial tel. 911 for emergencies requiring police, fire, or ambulance assistance.
Legal Aid -- While driving, if you are pulled over for a minor infraction (such as speeding), never attempt to pay the fine directly to a police officer; this could be construed as attempted bribery, a much more serious crime. Pay fines by mail, or directly into the hands of the clerk of the court. If accused of a more serious offense, say and do nothing before consulting a lawyer. In the U.S., the burden is on the state to prove a person's guilt beyond a reasonable doubt, and everyone has the right to remain silent, whether he or she is suspected of a crime or actually arrested. Once arrested, a person can make one telephone call to a party of his or her choice. The international visitor should call his or her embassy or consulate.
Mail -- At press time, domestic postage rates were 28¢ for a postcard and 44¢ for a letter. For international mail, a first-class letter of up to 1 ounce costs 98¢ (75¢ to Canada and 79¢ to Mexico); a first-class postcard costs the same as a letter. For more information go to www.usps.com.
If you aren't sure what your address will be in the United States, mail can be sent to you, in your name, c/o General Delivery at the main post office of the city or region where you expect to be. (Call tel. 800/275-8777 for information on the nearest post office.) The addressee must pick up mail in person and must produce proof of identity (such as a driver's license or passport). Most post offices will hold mail for up to 1 month, and are open Monday to Friday from 8am to 6pm, and Saturday from 9am to 3pm.
Always include zip codes when mailing items in the U.S. If you don't know your zip code, visit www.usps.com/zip4.
Newspapers & Magazines -- Pick up a copy of The Guide (there's one for both the South Rim and North Rim) at any entrance station to the Grand Canyon or online at www.nps.gov/grca/parknews/newspaper.htm. There's also a free online Trip Planner on the same site.
Smoking -- All hotel rooms, restaurants, bars, and public areas are nonsmoking within Grand Canyon National Park.
Taxes -- The United States has no value-added tax (VAT) or other indirect tax at the national level. Every state, county, and city may levy its own local tax on all purchases, including hotel and restaurant checks and airline tickets. These taxes will not appear on price tags. Arizona sales tax is 6.6%. The hotel tax in the Grand Canyon area is 7.74%.
Time -- The continental United States is divided into four time zones: Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), and Pacific Standard Time (PST). Alaska and Hawaii have their own zones. For example, when it's 9am in Los Angeles (PST), it's 7am in Honolulu (HST), 10am in Denver (MST), 11am in Chicago (CST), noon in New York City (EST), 5pm in London (GMT), and 2am the next day in Sydney.
Daylight saving time (summer time) is in effect from 1am on the second Sunday in March to 1am on the first Sunday in November, except in Arizona, Hawaii, the U.S. Virgin Islands, and Puerto Rico. Daylight saving time moves the clock 1 hour ahead of standard time.

Tipping -- In hotels, tip bellhops at least $1 per bag ($2-$3 if you have a lot of luggage) and tip the chamber staff $1 to $2 per day (more if you've left a big mess for him or her to clean up). Tip the doorman or concierge only if he or she has provided you with some specific service (for example, calling a cab for you or obtaining difficult-to-get theater tickets). Tip the valet-parking attendant $1 every time you get your car.
In restaurants, bars, and nightclubs, tip service staff and bartenders 15% to 20% of the check, tip checkroom attendants $1 per garment, and tip valet-parking attendants $1 per vehicle.
As for other service personnel, tip cab drivers 15% of the fare; tip skycaps at airports at least $1 per bag ($2-$3 if you have a lot of luggage); and tip hairdressers and barbers 15% to 20%.

Toilets -- You won't find public toilets or "restrooms" on the streets in most U.S. cities but they can be found in hotel lobbies, bars, restaurants, museums, department stores, railway and bus stations, and service stations. Large hotels and fast-food restaurants are often the best bet for clean facilities. Restaurants and bars in resorts or heavily visited areas may reserve their restrooms for patrons.
