Hi all,
So we get a sense of what phone number formats people are using, I
pulled all the *phone* and *contact:phone *tags from OSM in Canada.
The top 10 formats used are:
8819 phone"+#-###-###-####
4321 phone"###-###-####
4298 phone"+# ###-###-####
3012 phone"+# ### ### ####
2558 phone"+# ### ###-####
2471 phone"(###) ###-####
1087 phone"##########
946 phone"+#-
680 phone"+# ### #######
512 phone"+###########
So one of the recommended formats is the top one in use. But there
are 4 formats in high use which have the leading "+1", but have
different variants of spaces/hyphens:
8819 phone"+#-###-###-####
4298 phone"+# ###-###-####
3012 phone"+# ### ### ####
2558 phone"+# ### ###-####
Other facts:
* There are ~400 unique formats (when changing all digits to #) of
phone and contact:phone
* There are additionally ~45 phone numbers that use letters instead
of digits (eg 1-555-GOT-BEER)
* ";" separator is used occasionally to indicate multiple phone
numbers. " ", "," and "/" are also used.
* There are random comments in the phone number field (not sure
where these really should be?)
* Extensions are represented generally by "x" or "ext" or "ext."
* There are less than 1000 phone numbers using contact:phone instead
of phone, using ~40 unique formats
* I did not analyze phone_1 or fax or any other tags.
I will continue to cleanup phone numbers across the country which are
missing the leading +1 and or are not one of the 4 common formats
listed above. My thought is that
* I will leave the phone numbers of 1-555-GOT-BEER type.
* I will use ";" as multiple number separator.
* I will use "x" for extension.
* And I will be happy to cleanup the wonky ones with lots of text in
them if there is a direction of where this should move to.
Example for a radio station: "office (###) ###-####; on-air studio
(###) ###-####"
Feedback welcome.

Hi all,
Is there a preferred phone number format we use in Canada?
I noticed a bunch of phone numbers in Ottawa don't follow the
recommendations in https://wiki.openstreetmap.org/wiki/Key:phone,
namely:
* phone=/number/ where the /number/ should be in international
(ITU-T E.164 <http://en.wikipedia.org/wiki/E.164>) format
o phone=+<country code> <area code> <local number>, following
the ITU-T E.123 <http://en.wikipedia.org/wiki/E.123> and the
DIN 5008 <http://en.wikipedia.org/wiki/de:DIN_5008> pattern
o (phone=+<country code>-<area code>-<local number>, following
the RFC 3966/NANP <http://en.wikipedia.org/wiki/NANP> pattern)
Is there a preference which of these formats is used? Can anyone
run a query and see which is more popular in the country?
The reason I'm asking is that since a bunch of phone numbers leave
off the +1 (and have other errors), I want to align them to the
recommended format. I am wondering if I should have them in the
format of "+1 999 555 1234" or "+1-999-555-1234". If there is no
existing preference adopted in OSM Canada, I will use the latter to
cleanup the non-compliant phone numbers.
Comments?
I am also assuming we prefer "phone" over "contact:phone" as per
https://wiki.openstreetmap.org/wiki/Key:contact
