I came across a country list to choose your international telephone prefix. No option to type the number, gotta use the drop down list. It also included many '+1’s for American states.
There was a Chinese version of the web page, and all the country codes (UK, CA, etc) were translated as if whatever abbreviation you might guess. Highlights, IIRC, included BP -> (Chinese translation for) British Petroleum; IN -> (Chinese for) the word ‘in’; and SS -> (Chinese for) the Schutzstaffel.
