What country code starts from 0005?

The 00 is not part of the country code, it is a commonly used international access prefix. Country code +1 is North America, which includes the USA, Canada, and 18 island countries and territories in or near the Caribbean. North American area codes are always 3 digits, so you need two more digits. For example, +1 501 is in Arkansas, USA, but +1 506 is in New Brunswick, Canada. By coincidence, all +1 5XX area codes are in the US or Canada, although +1 500, 533, 544, and the future 566 are special codes for personal "follow-me" numbers and similar purposes; the person on the other end of such a number could be almost anywhere in the world.
