0014 is one of the international access prefixes used in Australia, for calls using the Primus network. Dial 0014 plus the country code, city code, and number.
Many areas use 00 or 001 as the international access prefix. Country code +1 is North America (USA, Canada, etc.), but you need the following 3 digits to be more specific. Country code +4 is an incomplete code, somewhere in Europe. You need either one or two more digits to be more specific.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
Country code +1 is the US, Canada, and various islands in or near the Caribbean. 34 is the first two digits of a 3-digit area code, but you need the next digit to tell where it is specifically:
+1 340 = U.S. Virgin Islands
+1 343 = Ottawa, ON, Canada
+1 345 = Cayman Islands
+1 347 = New York, NY, USA (Bronx, Brooklyn, Queens, Staten Island)
Unfortunately, you have included the dialing prefix with the code, making it more difficult to answer your question, since different places use different prefixes.
If you are in Australia, 0014 is the international dialing prefix for calls placed on the Primus network. To place an international call on Primus, dial 0014, followed by the country code, city code (if applicable), and subscriber number.
In most of the world, 00 is the international dialing prefix, which leaves you with telephone country code +1, which is North America, including the USA, Canada, and 18 miscellaneous island nations and territories, mostly in the Caribbean. You need the following three digits (i.e., two more digits) to narrow down the location. For example, +1 401 is Rhode Island, USA, +1 418 is Quebec City, Quebec, Canada, and +1 473 is the Caribbean island nation of Grenada.
However, several countries use 001 as the international dialing prefix, which would leave you with telephone country code +4, which is an incomplete code somewhere in Europe. You need one or two more digits to determine the country. For example, +41 is Switzerland, and +420 is the Czech Republic.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
