I need to make my telephone number clickable. You might be familiar with this in Gmail's clickable phone numbers that dial out to your mobile phone, for example.

I'm working on my resume, and I'm using the res class. It looks like with what I want to do I have to make some changes to my class file, but I'm a little hesitant to do so.

Here's what I want:

*RFC 3966 compatible URL tel:: https://www.rfc-editor.org/rfc/rfc3966#section-5.2 (see section 5.2)

I also want it to be formatted as an "ITU-T E.123 standard telephone number": http://www.itu.int/rec/T-REC-E.123-200102-I/e (see section 2.4)

So basically I want:

  • HTML source: "tel:15555555555"

  • Typeset as: "+1 555 555 5555" (clickable of course like HTML telephone links)

My final goal is to have a clickable link for a phone number without it looking visually different, just like my email address is. It is simply clickable and it goes to my email application.

Is there a package that does tel:? How do I integrate this telephone solution in res? Does anyone ever use clickable tel: links in PDFs?

*edit: I Found out here https://stackoverflow.com/questions/1164004/how-to-mark-up-phone-numbers that RFC 3966 supersedes RFC 2806.

UPDATE: I think I have escaped the domain of TeX with this problem. I used "You's" answer to make a clickable link that looks formatted properly. I'm just having issues with the functionality of the tel: standard among applications that use it. Not working: Foxit Reader, Gmail, Chrome (Windows OS). Working: Gmail mobile, mobile Quickoffice PDF viewer, Mobile dialer (Android OS).

  • You can try moderncv and use \href command in the Tel: part.

  • That is a nice idea. Are there PDF readers that know what to do with tel: URIs though?

  • Thank you percusse, I'd like to stick with res.cls class though, but the \href part helped! Apr 27, 2012 at 17:25
  • Raphink: I'm testing it now. I'm counting on the idea that they do. I'm using Foxit reader, and it doesn't seem to know what to do, except it prompts me whether I want to try to open it. I'm also going to test in Chrome, and on my mobile. Apr 27, 2012 at 17:28
  • I inspected a link that works in gmail: <a href="tel:222-333-4444" value="+1222333444" target="_blank">222-333-4444</a> I'm not sure that the hyperref package deals with these properly, or the applications don't understand the way it's being given to them. My browser just opens a new tab when I try "You's" method in the answers. Apr 27, 2012 at 17:43

Just use \href from hyperref:

\href{tel:15555555555}{+1 555 555 5555}
  • Thank you sir! I'm kind of curious how when I entered my email (in the tex file I needed no hyperref inclusion for the link to work, does this mean my pdf viewer is just awesome? I have since revised the tel and mailto links to be consistent. Apr 27, 2012 at 17:24
  • @projectdp It might be the case that Skype taking over stuff.

  • @percusse, that shouldn't matter. They are (to my understanding) using a non-RFC standard type called: callto:. Maybe I just need to figure out how applications know to use tel:? See my recent comments in my original post. Apr 27, 2012 at 17:45
  • It does not work for me. A click on the link just lunches google chrome. I have Skype installed. What should I have more? Feb 21, 2013 at 7:00

    Hello Igor, I know it's been a while but the tel: protocol association is defined in the Operating System. If you have Skype installed it should associate with the tel: protocol. If you want your system to open tel: protocol links in another application, simply update your association for tel: protocol to the desired application. You can do this in: Control Panel > Default Programs > Associate a file type or protocol with a program. If you're using another OS, try looking for protocol association documentation.

If error still persists, remember to enclose whole thing in extra curly braces

{\href{tel:+1XXXXXXXXXX}{+1 XXX XXX XXXX}}

I was getting an error so I put extra curly braces. Here is the resume header

{\Huge \scshape YOUR NAME} \\ \vspace{7pt}
{\href{tel:+1XXXXXXXXXX}{\faPhone\ +1 XXX XXX XXXX}} ~
\href{mailto:[email protected]}{\faEnvelope\ [email protected]} ~
