Area Codes -- The telephone area code for northwestern New Mexico, including Albuquerque and Santa Fe, is 505. For the rest of the state, including Taos, the code is 575.

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 is actually an organization of regional motor 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 [222-4357]).

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 -- In case of emergency, dial tel. 911. For more specific information, see chapters 5, 12, and 16.

Gasoline (Petrol) -- At press time, in the U.S., the cost of gasoline (also known as gas, but never petrol), is abnormally high. In New Mexico, prices run a little above the national average. 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).

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 27¢ for a postcard and 42¢ for a letter. For international mail, a first-class letter of up to 1 ounce costs 90¢ (69¢ 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 such). 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 -- The New Mexico Department of Tourism will send you a free state map. Call 800/545-2070 or 505/827-7400 (www.newmexico.org).

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. For up-to-the-minute information, contact AIDSinfo (tel. 800/448-0440 or 301/519-6616 outside the U.S.; www.aidsinfo.nih.gov) or the Gay Men's Health Crisis (tel. 212/367-1000; www.gmhc.org).

Police -- In case of emergencies, dial tel. 911. For local police stations, see chapters 5, 12, and 16.

Smoking -- New Mexico recently outlawed smoking at indoor public places, including restaurants and nightclubs. Some hotels offer rooms which allow smoking, though the number of these is dwindling.

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.

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 25¢ or 35¢ (no pennies, please). 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.
