\chapter{General Principles}
\section{Basic Ideas of the Package}
The \phone\ package aims to enable the user to typeset telephone numbers without any knowledge of the internal structure of the number or the national typographic conventions for typesetting phone numbers.

For instance, area codes are separated from the subscriber number in most countries. To typeset the phone number with the aid of the \phone\ package the user does not need to know which digits belong to the area code and which to the subscriber number. The package knows all area codes of the supported countries and will automatically typeset them correctly.
\begin{sidebyside}
  \phonenumber{03023125789}
\end{sidebyside}
The first three digits of this German phone number are recognized as the area code of Berlin, whereas in the following example the first six digits can be identified as the area code of the German spa town of Bad Schandau.
\begin{sidebyside}
  \phonenumber{03502225789}
\end{sidebyside}

The package does not aim to implement a particular norm. Rather, it follows the usual conventions for typesetting phone numbers. By setting options the user can determine the country the number is belonging to and select from various formatting options. This includes the additional output of the country calling code.

Furthermore, the package is able to check if a phone number is valid according to the national rules. Invalid numbers will lead to warnings during compilation.

\section{Commands}
\begin{Befehlsliste}
\Befehlsbeschreibung{usepackage}[\oarg{options}\Marg{phonenumbers}]
Loads the package and sets the \meta{options} globally, so that they will affect all phone numbers not having contradictory options of their own. Has to be used in the preamble.
\Befehlsbeschreibung{setphonenumbers}[\marg{options}]
Sets the \meta{options} for all following phone numbers not having contradictory options of their own. Can be used in the preamble or in the document body.
\Befehlsbeschreibung{phonenumber}[\oarg{options}\marg{number}\oarg{extension}]
Typesets a telephone number. The \meta{options} are valid only for this phone number.

The \meta{number} can be input in the local or in the international format. The local format is possible for supported countries only; the country has to be set by the
\option{country}
option
\vglAbschnitt{optionen-allgemein}.
The international format always begins with
\code{+}
or
\code{00}
followed by the country code
\vglAnhang{landeskennzahlen}.

Apart from a leading plus sign the \meta{number} has to consist of digits only. To structure the number spaces, brackets (round and square), slashes and hyphens may be input; these will be ignored.

For German and Austrian phone numbers an \meta{extension} can be given additionally, since extensions are often highlighted in German typography. If the optional argument is missing and the \meta{number} contains a hyphen, the part of the number after the (last) hyphen is recognized as extension if not only an area code precedes.

Numbers from supported countries are typeset according to the national conventions. Numbers from unsupported countries are structured in groups of two digits after the country calling code.
\Befehlsbeschreibung{AreaCodesGeographic}[\oarg{options}]
Typesets a list of geographic area codes for the country set globally or by a local option.
\Befehlsbeschreibung{AreaCodesNonGeographic}[\oarg{options}]{Typesets a list of non-geographic area codes (area codes for mobile phones and for other special purposes) for the selected country.}
\Befehlsbeschreibung{CountryCodes}
Typesets a list of valid country codes.
\end{Befehlsliste}

\section{Linking of Phone Numbers} \label{verlinkung}
On modern devices with telephony capabilities links on phone numbers can be used to call a number without having it to type. The \phone\ package generates such links if the \Paket{hyperref} package
\cite{hyperref}
is loaded additionally.

Independantly of their appearance in the text the phone numbers are linked including the country calling code (beginning with +) so that they can be reached from everywhere.

The appearance of the links can be set using \Paket{hyperref} options. For example, you could add the following line to the preamble to display all links on phone numbers in blue.

\begin{sourcecode}
  \usepackage[colorlinks=true,urlcolor=blue]{hyperref}
\end{sourcecode}

On classical personal computers such links are not usable though. If you need \Paket{hyperref}, but do not want to link phone numbers, use the \option{link} option
\sieheAbschnitt{optionen-allgemein}.

\UeberschriftOptionen{allgemein}
All options can be set globally with the aid of the \cs{usepackage} and the \cs{setphonenumbers} commands or locally for single phone numbers.
\begin{Befehlsliste}
\Optionsbeschreibung{country}{AT,DE,FR,UK,US}{DE}
Sets the country the number is belonging to.
\begin{center}
\begin{tabular}{>{\ttfamily}ll}
AT & Austria \\
DE & Germany \\
FR & France \\
UK & United Kingdom \\
US & United States, Canada and further countries
\vglAbschnitt{US-bereich}
\end{tabular}
\end{center}
Please contact the package author if you need support for further countries.

This option is ignored if the number is input in the international format. In this case the country is determined by the country code.

\Optionsbeschreibung{link}{on,off}{on}
Specifies whether phone numbers shall be linked if the \Paket{hyperref} package is loaded
\vglAbschnitt{verlinkung}.

\Optionsbeschreibung{foreign}{international,american,european,off}{off}
Specifies whether and in which form the country calling code will be output.

With \code{foreign=international} or simply \code{foreign} you will get a country calling code consisting of a plus sign followed by the country code (\eg\ 49 for German numbers). In this form the country calling code can be directly used on mobile phones. For landline calls the + has to be replaced by the international call prefix used in the country of the caller.
\begin{sidebyside}
  \phonenumber[foreign=international]{03023125789}
\end{sidebyside}
The choice \code{american} lets the country calling code begin with 011, the international call prefix used in North America.
\begin{sidebyside}
  \phonenumber[foreign=american]{03023125789}
\end{sidebyside}
With the choice \code{european} the number will begin with a double zero, used in most of Europe and further parts of the world.
\begin{sidebyside}
  \phonenumber[foreign=european]{03023125789}
\end{sidebyside}

For numbers from unsupported countries the choice
\code{foreign=off}
is treated like
\code{foreign=\linebreak[0]international}, which means that the country calling code will always be output for these numbers.

\Optionsbeschreibung{foreign-area-code-sep}{space,brackets}{space}
Sets the area code separator for numbers with country calling code. The International Telecommunication Union recommends not to use brackets in international numbers \cite[3]{ITU-123}.

\begin{sidebyside}
  \setphonenumbers{foreign,foreign-area-code-sep=brackets}
  \phonenumber[country=DE]{0441343396} \\
  \phonenumber[country=UK]{01514960123} \\
  \phonenumber[country=US]{2125550123}
\end{sidebyside}
The choice of
\code{brackets}
has no effect on French phone numbers, since in France brackets are never used in phone numbers.

\Optionsbeschreibung{home-country}{AT,DE,FR,UK,US,none}{none}
Sets the home country. Numbers from this country will be typeset without the country calling code independantly of the value of the \option{foreign} option.
\begin{sidebyside}
  \setphonenumbers{foreign,home-country=FR}
  \phonenumber[country=DE]{0441343396} \\
  \phonenumber[country=FR]{0199006789} \\
  \phonenumber[country=US]{2125550123}
\end{sidebyside}

\Optionsbeschreibung{home-area-code}{\meta{home area code},none}{none}
Sets the area code of your home area. Only the subscriber number will be output for numbers with this area code. Links
\vglAbschnitt{verlinkung}
will always include the area code.

The \option{home-country} option should to be set before the home area code. If this does not happen, the home country is set to the current value of the \option{country} option when you set a home area code.
\begin{sidebyside}
  \setphonenumbers{home-country=US,home-area-code=242,foreign}
  \phonenumber[country=US]{2125550123} \\
  \phonenumber[country=US]{2425550124} \\
  \phonenumber[country=DE]{0258163970}
\end{sidebyside}
Setting a home area code is allowed only for areas where the area code can be left out for local calls.
\Optionsbeschreibung{group-min}{3,4,5,6,7}{3}
In several countries telephone numbers are structured in groups of two digits. The value of this option sets the minimum length of a number part (country calling code, area code, subscriber number, extension) to which structuring shall be applied.
\begin{sidebyside}
  \setphonenumbers{country=AT}
  \phonenumber{04632503}[364] \\
  \phonenumber[group-min=5]{04632503}[364]
\end{sidebyside}
\end{Befehlsliste}

\UeberschriftUngueltig
To ensure robustness against errors, the compilation will never be aborted with an error message if an invalid number is given to the \cs{phonenumber} command. Rather, the \phone\ package will write warnings to the log file.
This will occur if
\begin{itemize}
\item the input is empty or contains illegal characters,
\item an extension is given for a non-German and non-Austrian phone number,
\item a number input in the international format consists of a country calling code only or does not contain a valid country code,
\item the number is not in accordance with the national rules of the selected country (only for supported countries).
\end{itemize}

All number components are divided into groups of two digits beginning from the end as a rule. Area codes whose last digit represents the tariff are an exception. This concerns so-called MABEZ numbers (\emph{Massenverkehr zu bestimmten Zielen}, \enquote{mass traffic to certain destinations}, used \eg\ for televoting, area code 01\,37\,X) and service numbers (area code 01\,80\,X).

\chapter{French Phone Numbers}
\UeberschriftGeltungsbereich \label{FR-bereich}
The French numbering plan
\cite{ARCEP}
is not only used for metropolitan France, but also for the most French overseas territories. This concerns
\begin{itemize}
\item Guadeloupe (Caribbean),
\item Martinique (Caribbean),
\item French Guiana (South America),
\item R\'eunion (Indian Ocean),
\item Mayotte (Indian Ocean),
\item Saint Pierre and Miquelon (off the east coast of Canada),
\item Saint Barth\'elemy (Caribbean),
\item Saint Martin (Caribbean),
\item the French Southern and Antarctic Lands (\emph{\foreignlanguage{french}{Terres australes et antarctiques françaises}}, Indian Ocean/Antarctica).
\end{itemize}
However, it is not used for the Pacific territories Wallis and Futuna, French Polynesia, and New Caledonia.

\UeberschriftAufbau
French phone numbers generally have ten digits and are structured in groups of two digits. The first digit is always 0.
\begin{sidebyside}
  \phonenumber[country=FR]{0199006789}
\end{sidebyside}
The second digit makes it possible to assign a number to one of five geographic zones or to a special purpose (\eg\ mobile telephony). Certain number ranges are reserved for overseas territories
\vglAnhang{vorwahlen-FR}.
\begin{sidebyside}
  \setphonenumbers{country=FR,area-code=place-and-number}
  \phonenumber{0199006789} \\
  \phonenumber{0536495678} \\
  \phonenumber{0596123456}
\end{sidebyside}

The leading 0 is omitted for calls from abroad.
\begin{sidebyside}
  \phonenumber[country=FR,foreign]{0199006789}
\end{sidebyside}

Numbers for machine to machine communication beginning with 07\,00 have more than ten digits. They have 14 digits in metropolitan France and 13 digits in the overseas territories \cite[19]{ARCEP}.
\begin{sidebyside}
  \phonenumber[country=FR]{07000123456789} \\
  \phonenumber[country=FR]{0700512345678}
\end{sidebyside}

Some companies and institutions have four-digit short numbers, which always begin with 3.
\begin{sidebyside}
  \phonenumber[country=FR]{3245}
\end{sidebyside}
Short numbers are linked
\vglAbschnitt{verlinkung} without the country calling code since they cannot be reached from abroad.

Despite the fact that the areas mentioned in section \ref{FR-bereich} are treated as one single net internally, there are different country codes within the French numbering plan:
\begin{center}
\begin{tabular}{rl}
33 & Metropolitan France \\
262 & R\'eunion, Mayotte, French Southern and Antarctic Lands \\
508 & Saint Pierre and Miquelon \\
590 & Guadeloupe, Saint Barth\'elemy, Saint Martin \\
594 & French Guiana \\
596 & Martinique \\
\end{tabular}
\end{center}
The first number of the following example is from Mayotte and thus using the country code 262, the second one from metropolitan France with the country code 33.
\begin{sidebyside}
  \setphonenumbers{country=FR,foreign}
  \phonenumber{0269123456} \\
  \phonenumber{0261913456}
\end{sidebyside}

For some areas the country code leads to doubling the first three digits, \eg\ in the case of Martinique (area code 05\,96).
\begin{sidebyside}
  \phonenumber[country=FR,foreign]{0596123456}
\end{sidebyside}
However, for Saint Pierre and Miquelon the area code 05\,08 is entirely omitted for calls from abroad \cite[13]{ARCEP}.
\begin{sidebyside}
  \phonenumber[country=FR,foreign]{0508123456}
\end{sidebyside}

In Saint Pierre and Miquelon it is possible as well to omit the area code for local calls and to dial six digits only \cite[13]{ARCEP}.
\begin{sidebyside}
  \setphonenumbers{country=FR,home-area-code=0508}
  \phonenumber{0508123456}
\end{sidebyside}
Since this is not possible in other areas of France, \code{0508} is the only legal value for the \option{home-area-code} option \vglAbschnitt{optionen-allgemein}.

Phone numbers in the territories of the North American Numbering Plan have ten digits. They consist of a three-digit \emph{area code}, a three-digit \emph{central office code}, and a four-digit \emph{subscriber number} and are structured accordingly.
\begin{sidebyside}
  \phonenumber[country=US]{2125550123}
\end{sidebyside}
Besides the structuring with two hyphens there are also other conventions
\vglAbschnitt{optionen-US}.

For local calls it is possible to leave out the area code in many places (seven-digit dialling).
\begin{sidebyside}
  \phonenumber[country=US]{5550123}

\KeineVerlinkung\ As an alternative the \option{home-area-code} option
\vglAbschnitt{optionen-allgemein} can be used in the corresponding areas. However, this is not possible everywhere \cite{NANPA-ten-digit} since some areas had to be given multiple area codes (called \emph{overlays}) because of number exhaustion.

For long-distance calls the \emph{trunk prefix} 1 has to be dialled first as a rule.
\begin{sidebyside}
  \phonenumber[country=US,trunk-prefix]{2125550123}

\chapter{Technical Remarks}
The \phone\ package uses the
\Paket{ltxcmds}
package as well as the \LaTeX\ 3 package
\Paket{l3keys2e}.

Hyphens within phone numbers are realized by
\verbcode:\kern1pt-\kern1pt:, \ie\ they are typeset with an additional distance of 1 point from the surrounding digits. The same goes for slashes too, which are output as
\verbcode:\kern1pt\slash\kern1pt:, allowing a line break after the slash. After a plus sign an additional distance is inserted as well
(\verbcode:+\kern1pt:).
The structuring of German, Austrian, French, British, and unsupported numbers is done by small spaces
\verbcode:\,:.

The \Paket{hyperref} command \cs{href} is used to link phone numbers. If \Paket{hyperref} is loaded, the command
\verbcode:\phonenumber{0441654321}:
will be expanded to
\begin{center}
\verbcode=\href{tel:+49441654321}{04\,41\kern1pt\slash\kern1pt65\,43\,21}=\,.
