Dear Will

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 don't have any other knowledge on this, unfortunately.
I have never thought of how the country codes were assigned, but it is indeed interesting.

Sorry I couldn't be more help!

Have a nice day,

I can answer questions regarding land line phone systems, wiring methods, troubleshooting, as well as restoration of antique phones. (1900's to 1980's) I am still learning about newer technologies like VOIP and other digital modes, but may still be able to help with these topics from time to time.


I have collected antique telephones since I was a teen, and been involved in wiring of home phone lines, as well as troubleshooting problems with them since around the same time.

I have studied basic electrical fundamentals through classes in a technical college, as well as extensive reading on the subject in my own time. I have also helped Electricians and telecom installers on and off for some time.
