[talk-au] Phone numbers

[Andrew Davidson]

TL;DR summary:

I'm happy to use E.123 international format for phone numbers or local 
format if they are not able to be called from overseas.

It depends. Like most things it gets complicated and boring very 
quickly. So strap yourself in... If you look at the wiki entry: 
https://wiki.openstreetmap.org/wiki/Key:phone

phone numbers can be in E.164, E.123, DIN5008, RFC3966, or NANP "format".

Turns out that E.164 and NANP are not formats rather they are standards 
for numbering plans. E.164 is for allocating international numbers and 
NANP for allocating numbers in North America.

RFC3966 is a standard for creating URIs of telephone numbers so they end 
up in the form tel:+1-201-555-0123 (and I doubt anyone has used this in 
OSM).

E.123 and DIN5008 (part of) define formats for writing down phone 
numbers. They both have a international and national format but the wiki 
doesn't say which one to use.

So this one is not OK (it's a way that some Germans and Austrians write 
international numbers but is not in E.123 or DIN5008)

Not OK (extra zero in front of 3)

OK (matches E.123 and DIN5008 international formats)

OK (E.123 national format)

OK (E.123 international doesn't need spaces. Not sure about DIN5008)

Not OK. E.164 number not in either national or international format

OK. These are not E.164 numbers (ie: can't call from overseas) but are 
in E.123 and DIN5008 local format.
