What's the global standard for international phone numbers?

Is there something like an ISO standard that governs the correct format to be used for an international phone number? I often see the plus symbol used to indicate the international dialing prefix (ex. +81 = Japan).





Is it standard to strip out all the spaces, parentheses, hyphens and other punctuation and just publish the number like this:





+81.01234567890





I am asking because I would like to standardize a company's international phone numbers on business cards, annual reports, promotional materials, websites, etc.What's the global standard for international phone numbers?
there are formatting standards (no dashes, use spaces to separate numbers)





a good summary is here:

i'm not sure on that one. i call india a lot, cause that is where my fiance' is. and there is a plus sign because i call from my cell and i have to push the 0 button down until a plus sign appears then dial the 91 for the country code then 44 for the city code then the rest of the number.





i am not sure if i was helpful or not.
There is no international standard format for this. however it is practical to break the number up to show the international dialling code, the local dialling code and then the number itself. It is also normal to show the number broken into two, three or four sets of numbers as this makes it easier to remember, for example a number in Russia, might be.





+ 7 4242 28 22 09





The + indicating the international dialling prefix, the 7 being the code for Russia, the 4242 being the area code in the Russian City, and the telephone number (282209) broken into groups of two numbers, could also be shown as





+7 4242 282 209








Hope that helps
