Advanced Math/International Country Telephone Codes.
Dear Prof Randy
We have different international telephone codes for every country.
There are 196 countries in the world.
Some examples :
USA, Canada : 1
UK : 44
India : 91
Russia : 7
Netherlands : 31
How those standards were set for each telephone country code by the International Telecommunications Union (ITU) ?
i.e. Is the Number codes given as per country names alphabetical sorting i.e. Afghanisation, Albania, Algeria etc
i.e. Afghanisation = 1, Albania = 2, Algeria = 3, but looks like this may be not the case as USA = 1.
Statistical analysis for the International Telephone codes
1.Min and Max Numbers
USA : 1 - Min Number
Uzbekistan : 998 - Max Number.
2. Telephone Code Sorting - Ascending Order
USA : 1
Kazakhstan, Russia : 7
Egypt : 20
Greece : 30
3.Telephone Code Sorting - Descending Order
Uzbekistan : 998
Kyrgyzstan : 996
Georgia : 995
Was a Random number selected for every international country telephone code for the standards ?
Some of the Whole Integer Numbers are not taken into account for example 2,3,4,5,6,8,9,10,11 etc. i.e. they are skipped.
International telephone codes were given on the basis of Grouping of countries region wise viz Africa, Asia, Europe, America, Antarctic ?
Awaiting your reply,
Thanks & Regards,

I really have no idea how the country codes are selected although I'm sure that whomever is responsible didn't use a random number generator. That's not to say that the selections were not arbitrary. I imagine that the guidelines and/or logic for the assignment of country codes evolved over time and that there is probably not an overarching rationale. Here's a question: why does Greenland have a different country code than Denmark, since it is, in fact, a territory?
Sorry I couldn't be of more help. Keep up the curiosity! I may need to flag a question as not in my expertise (like last time), but I'd still like to see them.
