Area Codes -- Several changes have been made to area-code dialing in New York over the past decade. New area codes have been added in western New York, Long Island, New York City, and the Hudson Valley/Catskill region, bringing the state total to 14. In addition, callers in New York City are now required to dial the area code for both local and long-distance calls (1 + the area code + the seven-digit local number) whether calling another borough or calling across the street. For a list of New York State area codes, consult the phone book or go to www.verizon.com.

Automobile Organizations -- 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. 800/222-4357; www.aaa.com). AAA has a nationwide emergency road service telephone number (tel. 800/AAA-HELP).

Business Hours -- Business hours in New York State don't differ much from those of the rest of the country, and are generally 9am to 5pm, with one notable exception: It may be a tired cliché, but they don't call New York City "the city that never sleeps" for nothing. Although some stores close at 7pm, many are open until 9pm, and a few as late as 11pm. Most restaurants serve until 11pm, and later on weekends. Some diners serve breakfast all night to bar-crawlers and club kids, and 24-hour convenience stores on every other block sell an assortment of items you might need during the night, such as groceries, beer, ice cream, cigarettes, and cold remedies.

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. In general, grocery and convenience stores sell beer and other products that are less than 6% alcohol by volume (like wine coolers). Many of these stores are open 24 hours, but state law forbids them to sell alcohol from 3am to noon on Sunday. Wine and spirits are sold at liquor stores, also called package stores. Hours vary, but by law they must remain closed from midnight to 8am Monday through Saturday. Some stores may be open from noon to 9pm on Sunday, but many are closed. All liquor stores are closed Christmas Day.

Restaurants and bars can't serve drinks before 8am Monday through Saturday, or before noon on Sunday. Closing time for bars, taverns, and nightclubs varies by county. Albany, Buffalo, and New York City bars close at 4am; in Rochester and Syracuse they close at 2am. In quieter areas, closing time comes as early as 1am. 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 DWI ("driving while intoxicated"), so don't even contemplate drinking and driving.

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 the nation's capital, Washington, D.C. Some consulates are located 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 -- Call tel. 911 to report a fire, call the police, or get an ambulance anywhere in the United States. This is a toll-free call. (No coins are required at public telephones.)

Gasoline (Petrol) -- Over the past two years in the U.S., the cost of gasoline (also known as gas, but never petrol) has fluctuated greatly, from less than $2 per gallon to more than $4.50 (at press time, the cost is just under $3 per gallon in most parts of the state). Gasoline in New York State is just above the national average, while filling the tank in New York City is about as expensive as you'll find in the country. 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). The Tuesday after the first Monday in November is Election Day, a federal government holiday in presidential-election years (held every 4 years, and next in 2012).

Hotlines -- In New York City, the main hotline for all things metropolitan is tel. 311. For tourism matters and questions across the state, call tel. 800-CALL NYS. For issues of safety, call the Statewide Public Security Tips Hotline at tel. 866/SAFE-NYS, or 888/NYC-SAFE in New York City.

Insurance -- For information on traveler's insurance, trip cancellation insurance, and medical insurance while traveling please visit www.frommers.com/planning.

Internet Access -- Cybercafes and FedEx Offices (formerly Kinko's) are good places to go for Internet access in cities. To find a cybercafe, try www.cybercafe.com. New York's most rural areas, such as parts of the Catskill and Adirondack mountains and the North Country, are not well connected.

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. After being arrested, a person can make one telephone call to a party of his or her choice. International visitors should call your embassy or consulate. If you find yourself in need of legal representation, contact the New York State Bar Association's Lawyer Referral and Information Service (tel. 800/342-3661 or 518/487-5709; www.nysba.org).

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 (driver's license, passport, and so forth). 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.

Newspapers & Magazines -- The New York Times, New York Daily News, the Wall Street Journal, and USA Today are sold at newsstands everywhere in New York City and are generally available in hotels and corner newspaper boxes throughout the state. Major cities have their own daily papers. The largest of these are the Buffalo News, Rochester Democrat and Chronicle, Syracuse Post-Standard, and Albany Times Union. In Manhattan, magazine stores carrying all kinds of domestic and international publications are located in most neighborhoods. In other cities, bookstore chains such as Barnes & Noble carry a wide selection of magazines.

Police -- In nonemergency situations, call the nearest police station. Local police precinct telephone numbers can be found in the blue "government" pages of the phone book. In an emergency, call tel. 911, a toll-free call (no coins are required at public telephones).

Smoking -- The legal age to purchase cigarettes and other tobacco products in New York State is 18. But you won't find many places left to smoke them, aside from your hotel room. A state law passed in 2003 prohibits smoking in almost all public venues and in the workplace. This includes bars and restaurants, although smokers can still light up in cigar bars, designated outdoor areas of restaurants, and some private clubs. The law does not affect Native American-run casinos, and smoking is still permitted there.

Taxes -- Sales tax in New York State varies between 7.25% and 8.75% (the state tax is 4.25%, and counties generally tack on another 3% or 4%). On top of the sales tax, hotel occupancy taxes can add as much as 5% to hotel and motel bills; an additional 5% typically applies to car rentals as well.

Telephones -- Many convenience groceries and packaging services sell prepaid calling cards in denominations up to $50; for international visitors these can be the least expensive way to call home. Many public pay phones at airports now accept American Express, MasterCard, and Visa credit cards. Local calls made from pay phones in most locales cost either 35¢ or 50¢. 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 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.

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. New York State is located in Eastern Standard Time. So, for example, noon in New York City (EST) is 11am in Chicago (CST), 10am in Denver (MST), 9am in Los Angeles (PST), 8am in Anchorage (AST), 7am in Honolulu (HST), 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 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 areas of New York, 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.
