as usual the problem with standards is that there are many of them.
I can not comment about other countries, but even in Germany it's a bit messier
as you described.
Most people in the telco world use E.164 or E.123 type for formatting to
represent phone numbers.
But many normal businesses use the national standard "DIN 5008". This
extends E.123 with the usage of a dash to separate local extensions in
international format, e.g.:
+49 123 123456-123
Many people recommend this format if the company is doing business mainly
national, and E.123 if the company is doing business international.
I don't see a problem here.
DIN 5008 is a German standard, which would be considered a National
Format. I would fully support Google's libphonenumber of using such a
standard for formatting National Numbers for Germany in that manner.
However, it does NOT use this standard for National formatting.
However, for people outside of Germany who want to write out its phone
numbers, ITU E.123 standard for International Format should be followed.
National: +49 123 123456-123
International: +49 123 123456 ext. 123
libphonenumber is NOT using DIN 5008 for National:
<!-- Due to the high complexity of ranges in the German numbering
scheme, the regular
expressions here have been automatically simplified to reduce size.
This means that
in some cases there may be false positives (especially in fixed line
ranges), but since
German ranges differ so much by length anyway, false positives are
already common. -->
The Zoo Duisberg is at +4920360444250. Libphonenumber outputs expected
results.
- National Format: 0203 60444250
- International Format: +49 203 60444250
With extension:
- National: 0203 60444250 ext. 134
- International: +49 203 60444250 ext. 134
Maybe you want to submit a request to Google's Libphonenumber to follow
DIN 5008 for National! I would comment in support! I would be annoyed if
libphonenumber did not follow my national standard.
