055 is not a country code. Numbers inside a country start like this: Bakcell (Azerbaijan), du (United Arab Emirates), 019mobile (Israel), Kamphaeng Phet/Phitsanulok/Sukhothai/Tak/Uttaradit (Thailand) and others. The first digit 0 is the trunk prefix for domestic calls and is dropped from abroad.

If a number starts with +, the first 1–3 digits are the country code. If it starts with 0 (8 in Russia and Kazakhstan), it is a domestic number: an area or operator code follows, and from abroad the 0 or 8 is replaced with + and the country code. The same digits can mean different places, so where the call came from matters.
