Fast Facts

American Express -- There's an American Express Travel Service office at 1501 K St. NW, entrance on 15th St. (tel. 202/457-1300).

Area Codes -- Within the District of Columbia, it's 202. In suburban Virginia, it's 703. In suburban Maryland, it's 301. You must use the area code when dialing any number, even local calls within the District or to nearby Maryland or Virginia suburbs.

Automobile Organizations -- Auto clubs will supply maps, suggested routes, guidebooks, accident and bail-bond insurance, and emergency road service. The American Automobile Association (AAA) is the major auto club in the United States. If you belong to an auto club in your home country, inquire about AAA reciprocity before you leave. You may be able to join AAA even if you're not a member of a reciprocal club; to inquire, call AAA (tel. 800/763-9900). AAA is actually an organization of regional auto clubs, so look under "AAA Automobile Club" in the White Pages of the telephone directory. AAA has a nationwide emergency road service telephone number (tel. 800/AAA-HELP, or 800/222-4357).

Business Hours -- Offices are usually open weekdays from 9am to 5pm. Most banks are open Monday through Thursday from 9am to 3pm, with some staying open until 5pm; 9am to 5pm on Friday, and sometimes Saturday mornings. Stores typically open between 9 and 10am and close between 5 and 6pm from Monday to Saturday. Stores in shopping complexes or malls tend to stay open late, until about 9pm on weekdays and weekends, and many malls and larger department stores are open on Sundays.

Cameras & Film -- Never pack film in checked bags, because the powerful scanners in U.S. airports can fog film. The film you carry with you can be damaged by scanners as well. X-ray damage is cumulative; the more times you put it through a scanner, the more likely the damage. Keep in mind that airports are not the only places where your camera may be scanned: Highly trafficked attractions are X-raying visitors' bags with increasing frequency.

Most photo supply stores sell protective pouches designed to block damaging X-rays. The pouches fit both film and loaded cameras. They should protect your film in checked baggage, but they also may raise alarms and result in a hand inspection.

You'll have little to worry about if you are traveling with digital cameras. Digital camera and storage cards are not affected by airport X-rays, according to Nikon.

Carry-on scanners will not damage videotape, but the magnetic fields emitted by the walk-through security gateways and handheld inspection wands will. Always place your loaded camcorder on the screening conveyor belt or have it hand-inspected. Be sure your batteries are charged, as you may be required to turn the device on to ensure that it's what it appears to be.

Congresspersons -- To locate a senator or congressional representative, call the Capitol switchboard (tel. 202/225-3121). Point your Web browser to www.senate.gov and www.house.gov to contact individual senators and congressional representatives by e-mail, find out what bills are being worked on, the calendar for the day, and more.

Currency -- The most common bills are the $1 (a "buck"), $5, $10, and $20 denominations. There are also $2 bills (seldom encountered), $50 bills, and $100 bills (the last two are usually not welcome as payment for small purchases).

Coins come in seven denominations: 1¢ (1 cent, or a penny); 5¢ (5 cents, or a nickel); 10¢ (10 cents, or a dime); 25¢ (25 cents, or a quarter); 50¢ (50 cents, or a half dollar); the gold-colored Sacagawea coin, worth $1; and the rare silver dollar.

Customs -- What You Can Bring into Washington, D.C. Every visitor more than 21 years of age may bring in, free of duty, the following: (1) 1 liter of wine or hard liquor; (2) 200 cigarettes, 100 cigars (but not from Cuba), or 3 pounds of smoking tobacco; and (3) $100 worth of gifts. These exemptions are offered to travelers who spend at least 72 hours in the United States and who have not claimed them within the preceding 6 months. It is altogether forbidden to bring into the country foodstuffs (particularly fruit, cooked meats, and canned goods) and plants (vegetables, seeds, tropical plants, and the like). Foreign tourists may carry in or out up to $10,000 in U.S. or foreign currency with no formalities; larger sums must be declared to U.S. Customs on entering or leaving, which includes filing form CM 4790. For details regarding U.S. Customs and Border Protection, consult your nearest U.S. embassy or consulate, or U.S. Customs (tel. 202/927-1770; www.customs.ustreas.gov).

What You Can Take Home from Washington, D.C.: --Canadian Citizens: For a clear summary of Canadian rules, write for the booklet I Declare, issued by the Canada Border Services Agency (tel. 800/461-9999 in Canada, or 204/983-3500; www.cbsa-asfc.gc.ca).

U.K. Citizens: For information, contact HM Customs & Excise at tel. 0845/010-9000 (from outside the U.K., 020/8929-0152), or consult their website at www.hmce.gov.uk.

Australian Citizens: A helpful brochure available from Australian consulates or Customs offices is Know Before You Go. For more information, call the Australian Customs Service at tel. 1300/363-263, or log on to www.customs.gov.au.

New Zealand Citizens: Most questions are answered in a free pamphlet available at New Zealand consulates and Customs offices: New Zealand Customs Guide for Travellers, Notice no. 4. For more information, contact New Zealand Customs, The Customhouse, 17-21 Whitmore St., Box 2218, Wellington (tel. 04/473-6099 or 0800/428-786; www.customs.govt.nz).

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. Liquor stores are closed on Sunday. District gourmet grocery stores, mom-and-pop grocery stores, and 7-11 convenience stores often sell beer and wine, even on Sunday.

Bars and nightclubs serve liquor until 2am Sunday through Thursday and until 3am Friday and Saturday.

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. And nothing will ruin your trip faster than getting a citation for DUI ("driving under the influence"), so don't even think about driving while intoxicated.

Drugstores -- CVS, Washington's major drugstore chain (with more than 40 stores), has two convenient 24-hour locations: in the West End, at 2240 M Street NW (tel. 202/296-9877), and at 6 Dupont Circle (tel. 202/785-1466), both with round-the-clock pharmacies. Check your phone book for other convenient locations.

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 located in Washington, D.C. If your country isn't listed below, call for directory information in Washington, D.C. (tel. 202/555-1212) or log on to www.embassy.org/embassies.

Emergencies -- Call tel. 911 for police, fire, and medical emergencies. This is a toll-free call. (No coins are required at public telephones.)

If you encounter serious problems, contact the Traveler's Aid Society International (tel. 202/546-1127; www.travelersaid.org), a nationwide, nonprofit, social-service organization geared to helping travelers in difficult straits, from reuniting families separated while traveling, to providing food and/or shelter to people stranded without cash, to emotional counseling. Traveler's Aid operates help desks at Washington Dulles International Airport (tel. 703/572-8296), Ronald Reagan Washington National Airport (tel. 703/417-3972), and Union Station (tel. 202/371-1937).

Gasoline (Petrol) -- At press time, in the U.S., the cost of gasoline (also known as gas, but never petrol), is abnormally high -- over $3 a gallon. Taxes are already included in the printed price, but these vary by jurisdiction, with Northern Virginia's gas tax the lowest in the metropolitan area. One U.S. gallon equals 3.8 liters or .85 imperial gallons. Fill-up locations are known as gas or service stations.

Holidays -- Banks, government offices, post offices, and many stores, restaurants, and museums are closed on the following legal national holidays: January 1 (New Year's Day), the third Monday in January (Martin Luther King, Jr., Day), the third Monday in February (Presidents' Day), the last Monday in May (Memorial Day), July 4 (Independence Day), the first Monday in September (Labor Day), the second Monday in October (Columbus Day), November 11 (Veterans' Day/Armistice Day), the fourth Thursday in November (Thanksgiving Day), and December 25 (Christmas). The Tuesday after the first Monday in November is Election Day, a federal government holiday in presidential-election years (held every 4 years, this year, 2008, in fact).

Hospitals -- If you don't require immediate ambulance transportation but still need emergency-room treatment, call one of the following hospitals (and be sure to get directions): Children's Hospital National Medical Center, 111 Michigan Ave. NW (tel. 202/884-5000); George Washington University Hospital, 900 23rd St. NW at Washington Circle (tel. 202/715-4000); Georgetown University Medical Center, 3800 Reservoir Rd.

Legal Aid -- 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. Here 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. International visitors should call their embassy or consulate.

Lost & Found -- Be sure to tell all of your credit card companies the minute you discover your wallet has been lost or stolen, and file a report at the nearest police precinct. Your credit card company or insurer may require a police report number or record of the loss. Most credit card companies have an emergency toll-free number to call if your card is lost or stolen; they may be able to wire you a cash advance immediately or deliver an emergency credit card in a day or two. Visa's U.S. emergency number is tel. 800/847-2911 or 410/581-9994. American Express cardholders and traveler's check holders should call tel. 800/221-7282. MasterCard holders should call tel. 800/307-7309 or 636/722-7111. For other credit cards, call the toll-free number directory at tel. 800/555-1212.

If you need emergency cash over the weekend when all banks and American Express offices are closed, you can have money wired to you via Western Union (tel. 800/325-6000; www.westernunion.com).

Mail -- At press time, domestic postage rates were 26¢ for a postcard and 41¢ for a letter. For international mail, a first-class postcard costs 69¢ to Canada and Mexico and 90¢ to all other countries. For more information go to www.usps.com and click on "Calculate Postage."

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 (driver's license, passport, or something similar). Most post offices will hold your 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.

Maps -- Free city maps are often available at hotels and throughout town at tourist attractions. You can also contact the Washington, D.C. Convention and Tourism Corporation, 901 7th St. NW, 4th Floor, Washington, DC 20001 (tel. 202/789-7000).

Passports -- For Residents of Australia: You can pick up an application from your local post office or any branch of Passports Australia, but you must schedule an interview at the passport office to present your application materials. Call the Australian Passport Information Service at tel. 131-232, or visit the government website at www.passports.gov.au.

For Residents of Canada: Passport applications are available at travel agencies throughout Canada or from the central Passport Office, Department of Foreign Affairs and International Trade, Ottawa, ON K1A 0G3 (tel. 800/567-6868; www.ppt.gc.ca). Note: Canadian children who travel must have their own passport. However, if you hold a valid Canadian passport issued before December 11, 2001, that bears the name of your child, the passport remains valid for you and your child until it expires.

For Residents of Ireland: You can apply for a 10-year passport at the Passport Office, Setanta Centre, Molesworth Street, Dublin 2 (tel. 01/671-1633; www.irlgov.ie/iveagh). Those under age 18 and over 65 must apply for a €12 3-year passport. You can also apply at 1A South Mall, Cork (tel. 021/272-525), or at most main post offices.

For Residents of New Zealand: You can pick up a passport application at any New Zealand Passports Office or download it from their website. Contact the Passports Office at tel. 0800/225-050 in New Zealand or 04/474-8100, or log on to www.passports.govt.nz.

Police -- In an emergency, dial tel. 911. For a nonemergency, call tel. 202/727-1010.

Smoking -- The District is smoke free, meaning that the city bans smoking in restaurants, bars, and other public buildings. Smoking is permitted outdoors, unless otherwise noted.

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.

The sales tax on merchandise is 5.75% in the District, 5% in Maryland, and 4.5% in Virginia. The tax on restaurant meals is 10% in the District, 5% in Maryland, and 4.5% in Virginia.

In the District, you pay 14.5% hotel tax. The hotel tax in Maryland varies by county from 5% to 8%. The hotel tax in Virginia also varies by county, averaging about 9.75%.

Telephone, Telegraph, Telex & Fax -- Generally, hotel surcharges on long-distance and local calls are astronomical, so you're better off using your cellphone or a public pay telephone. Most long-distance and international calls can be dialed directly from any phone. For calls within the United States and to Canada, dial 1 followed by the area code and the seven-digit number. For other international calls, dial 011 followed by the country code, city code, and the number you are calling.

Calls to area codes 800, 888, 877, and 866 are toll-free. However, calls to area codes 700 and 900 (chat lines, bulletin boards, "dating" services, and so on) can be very expensive -- usually a charge of 95¢ to $3 or more per minute, and they sometimes have minimum charges that can run as high as $15 or more.

For reversed-charge or collect calls, and for person-to-person calls, dial the number 0 and then the area code and number; an operator will come on the line, and you should specify whether you are calling collect, person-to-person, or both. If your operator-assisted call is international, ask for the overseas operator.

For local directory assistance ("information"), dial 411; for long-distance information, dial 1, then the appropriate area code and 555-1212.

Telegraph and telex services are provided primarily by Western Union. You can telegraph money, or have it telegraphed to you, very quickly over the Western Union system, but this service can cost as much as 15% to 20% of the amount sent.

Most hotels have fax machines available for guest use (be sure to ask about the charge to use it). Many hotel rooms are even wired for guests' fax machines. A less expensive way to send and receive faxes may be at stores such as The UPS Store (formerly Mail Boxes Etc.).

Time -- The continental United States is divided into four time zones: Eastern Standard Time (EST) -- this is the time zone into which Washington, D.C., falls; 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 takes effect at 2am the second Sunday in March until 2am the first Sunday in November, except in Arizona, Hawaii, the U.S. Virgin Islands, and Puerto Rico. Daylight savings moves the clock 1 hour ahead of standard time. For the correct time, call tel. 202/844-2525.

Tipping -- Tips are a very important part of certain workers' income, and gratuities are the standard way of showing appreciation for services provided. (Tipping is certainly not compulsory if the service is poor!) 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 disaster area 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 15% to 20% of the check, tip bartenders 10% to 15%, 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. If possible, avoid the toilets at parks and beaches, which tend to be dirty; some may be unsafe. Restaurants and bars in resorts or heavily visited areas may reserve their restrooms for patrons.
