Fast Facts

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

Area Codes -- Within the District of Columbia, it's 202. In Northern Virginia, it's 703. In D.C.'s Maryland suburbs, it's 301. You must use the area code when dialing any number, whether it's a local 202, 703, or 301 phone number.

Automobile Associations -- Motor 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 a motor 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. 866/636-2377; www.aaa.com). AAA has a nationwide emergency road service telephone number (tel. 800/AAA-HELP [222-4357]). For travel planning, call tel. 800/436-4222.

Business Hours -- Offices are usually open weekdays from 9am to 5pm. Most banks are open from 9am to 3pm Monday through Thursday 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.

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-Eleven 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 in 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.

Electricity -- Like Canada, the United States uses 110-120 volts AC (60 cycles), compared to 220-240 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.

If you encounter serious problems, contact the Travelers 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.

Gasoline (Petrol)) -- At press time, in the U.S., the cost of gasoline (also known as gas, but never petrol), is abnormally high, over $4 a gallon, and expected to remain that high or escalate even higher. Taxes are already included in the printed price. 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).

Internet Access -- Many hotels offer guests free or inexpensive use of computers and Internet access in their business centers. If yours doesn't, find out where the nearest FedEx Kinko's is; these copy shops have computer stations with fully loaded software and Wi-Fi. In Washington's Dupont Circle neighborhood, the Kramerbooks and Afterwords bookstore, 1517 Connecticut Ave. NW (tel. 202/387-1400), has one computer available for free Internet access, with a 15-minute time limit. For other listings and locations of Internet kiosks in D.C., check www.cybercaptive.com and www.cybercafe.com.

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 your 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 27¢ for a postcard and 42¢ for a letter. For international mail, a first-class letter of up to 1 ounce costs 94¢ (72¢ to Canada and Mexico); a first-class postcard costs the same as a letter. 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, and so on). 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.

Medical Conditions -- If you have a medical condition that requires syringe-administered medications, carry a valid signed prescription from your physician; syringes in carry-on baggage will be inspected. Insulin in any form should have the proper pharmaceutical documentation. If you have a disease that requires treatment with narcotics, you should also carry documented proof with you -- smuggling narcotics aboard a plane carries severe penalties in the U.S.

For HIV-positive visitors, requirements for entering the United States are somewhat vague and change frequently.

International visitors to the U.S. can obtain a visa application at the same website. Note: Children are required to present a passport when entering the United States at airports. More information on obtaining a passport for a minor can be found at http://travel.state.gov. Allow plenty of time before your trip to apply for a passport; processing normally takes 4 to 6 weeks (3 weeks for expedited service) but can take longer during busy periods (especially spring). And keep in mind that if you need a passport in a hurry, you'll pay a higher processing fee.

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).

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, 6% in Maryland, and 5% in Virginia. Restaurant tax is 10% in the District, 6% in Maryland, and varied in Virginia, depending on the city and county. Hotel tax is 14.5% in the District, varied 5% to 8% in Maryland, and averages about 9.75% in Virginia.

Telegraph, Telex & Fax -- Telegraph and telex services are provided primarily by Western Union (tel. 800/325-6000; www.westernunion.com). You can telegraph (wire) 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 wired for guests' fax machines. A less expensive way to send and receive faxes may be at stores such as the UPS Store.

Time -- The continental United States is divided into four time zones: Eastern Standard Time (EST; this is Washington, D.C.'s time zone), 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 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 -- 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 cabdrivers 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.
