To call abroad, dial your international access prefix, then the country code, city code, and subscriber number.
The international access prefix depends on where you are calling from. For example, if you are in Western Europe, the prefix is 00, which is the most commonly used prefix around the world. However, in the USA and Canada, the prefix is 011. Australia uses 0011, Japan uses 010, and Russia uses 8~10. If you're using a GSM mobile phone, though, you don't have to worry about which prefix to use: just program the number with the plus sign and the country code.
The country code is a number between 1 and 999 that identifies a nation or an overseas territory. It is usually written with a plus sign, where the plus sign indicates "insert your international access prefix here." For example, France is +33, New Zealand is +64, Ghana is +233, Fiji is +679, and Russia and Kazakhstan are +7.
The city code is a domestic area code, but in most(but not all) countries where area codes begin with 0, you must drop the leading 0. For example, Amsterdam is 020 within the Netherlands, but becomes +31 20 internationally. However, Italy and a handful of African countries have numbers that keep the zero, like Rome's 06 area code which becomes +39 06. Also, a few countries do not have area codes or city codes, as such.
The subscriber number is the rest of the telephone number that you are trying to reach.
Area code 49 is the country code for Germany. It is used for international dialing to reach Germany from abroad. Within Germany, area codes vary by region and city, with the country code itself being used when dialing internationally.
The country dialing code +1632 is for the Philippines, specifically for the area of Metro Manila. Dialing codes are used to identify specific regions within a country for telephone calls. In the Philippines, the area code for Metro Manila is 02, but when dialing from abroad, it is preceded by the country code +63.
The dialing code 00601 is not associated with London or the UK. In fact, it is likely a non-standard or fictional code, as UK dialing codes typically begin with 0 followed by a 2-5 digit area code. For London, the area codes start with 020. If you're looking for specific dialing codes in London, the standard code is 020.
Area code +86 is the international dialing code for China. When dialed from outside the country, it is preceded by a "+" sign, which indicates that it is an international call. The "0" that follows is typically used for domestic dialing within China when calling a specific area code, but it is not included when dialing from abroad.
UK telephone area codes were first assigned in 1958.

There is no such code as 475 in France. French Postal zip codes have two digits for regions, or five for localities. The international dialing code is +33. The national area dialing codes (now included in the phone number) have only two digits (01 to 05).
Beginning in 2001, in preparation for the 878 overlay area code (which serves the same geographic territory as the 412 and 724 area codes combined), all local calls in area codes 412, 724, and 878 require 10-digit dialing.
