Or more likely, they had a mutual agreement until Britain wanted its own thing, so they exit the deal. Seems like something the English would do. We could have called it Brexit or something
It's not a million miles away from the truth. The UK and France were the main advocates behind the ITU, so they got +33 and +44. Which is...fine...but I've not come across why NA got +1, etc. or even why those numbers were chosen at all.
It’s interesting to me that Africa is 2. I’d assume that when these were implemented Africa would be a cultural afterthought and Europe would’ve gotten number 2.
US is part of the NANP which means they have their own system for beyond +1, which is shared with Canada and half the Caribbean, and so they were given the whole of +1 rather than +10, +11, +12 etc. all resolving to the same thing, or +10 being for about 10 different countries while +11 was for one
Then the Soviet Union wanted a single digit too, which is why Russia and Kazakhstan share +7
All of the USSR was +7 IIRC. Most changed it after independence, notice how the Baltics, Belarus and whatnot have previously unassigned three-character numbers instead of two like most of Europe (except microstates). They only got their numbers in the 90s, and no shorter ones were available. +37 just became available since east Germany didn't exist anymore.
Same with the former Yugoslavian countries, all of YU used +38, when they split up they had to split up +38 too.
I love how the division in Europe vaguely looks like the Protestant Reformation led to different prefix numbers (I know I know, Poland & co don't match)
The various reverse lookup services all seem to be strongest in different areas, but generally I start with tineye and Yandex and only try the others if I don't find what I need.
