Mandarin is the official language, though other dialects are also spoken. The most commonly used foreign language is English. Taxi drivers, however, generally only speak Mandarin or Taiwanese.

Currency
The unit of currency is the New Taiwan Dollar (NT$). Bill denominations are NT$2000, NT$1000, NT$500, NT$200, and NT$100. Coin denominations are NT$1, NT$5, NT$10, NT$20, and NT$50. As of August 2008, the exchange rate was quoted around NT$31 to one US Dollar. Foreign currencies can be exchanged at the airport upon arrival, or at government-authorized banks, tourist hotels, and large department stores. Receipts are given when currency is exchanged, and must be presented in order to exchange unused NT Dollars before departure.

One local call from a pay phone costs NT$1 for 1 minute, after which additional coins are needed or the line will be automatically disconnected. On private phones, the overseas operator may be reached by dialing "100." International calls can be made from private cell phones, public IDD phones, or hotel IDD phones. International direct dialing rates are calculated every six seconds. The international access code is 002, 005, 006, 007, 009, and 019. For example, you need to dial 002-1-415-555-1212 to reach directory assistance (555-1212) in San Francisco which has the area code of “415” and the country code of “1”. For incoming calls, Taiwan's country code is 886 and Taipei's city code is 2. To reach Taipei Grad Hotel outside Taiwan, one would need to dial 886-2-2720-1234 after dialing the international access code.
