Standard telephone number format?

(650) 123-1234. The 1 before the area code is implied since you need to dial it anyway when calling a different area code. --Mike-- The Internet is a place where absolutely nothing happens. -- Strong Bad 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!

In India numbers can be represented as (471) 255-5777 format like US. Dept. of Telecom standardised to 10 digit phone numbers. The country code is not required. Though in India to dial another area code, you have to preceed it with 0 [0 471 255 5777] instead of a 1 as in US. By the way, is that your home phone number in TVM?

Phone number formats differ across countries :- US numbers go like +1-650-123-1234 In India (in Trivandrum anyway) we have +91-471-2555777 Nish

To add to that, over here we have: 01111-666666 01111-55555 0111-333-4444 0111-333-333 The zero is the start of the area code (locally for example it is 01884) which is dropped when the international code is added (e.g. 44-1884). After the area code follows the number, of which the five digit type is (AFAIK) now derecated and typically only for older lines, whereas the six digit variety is the most common, with areas like London and Bristol commonly reformatting the numbers to include the last digit of the area code as the first digit of the number (I don't know that for a fact, they may just have a four digit code and a six or seven digit number, because those areas would have had exchanges before the rest of the country? :~ Special codes like toll free or local rate have special four digit area codes and seven digit numbers). The international code is obviously dropped for all UK numbers and the area code is dropped for all in-area numbers. Area codes don't follow geographic areas, they are set much like the area prefix on our postcodes are. I don't think a standard format would be possible, except to say "a number containing the digits 0 to 9 that is between, say, five and 30 digits long".

Eek! I had no idea! I thought that internationally there was all one big unified length/format, and that it was the omission of country/area codes and the addings of various "."s, "-"s, and "+"s that would differ and therefore need to be standardized in its formatting. Wow, well, I learned something new today!

We can't even agree on a language - what makes you think we can agree on a telephone number format? :rolleyes:

Just to blow you away, You can still find in odd locations around the world telephone numbers that end with an alphabetical letter. Like L, R, S, M. etc I'll let you guess what the letter is for. :-) Regardz Colin J Davies

Actually, the international standard limits a full number to 15 digits. (Excluding, I believe the single digit international access prefix itself.)

Including country codes, phone numbers must consist of no more than 15 digits 0-9. The use of characters in phone numbers assumes you will use the corresponding digit on the phone pad.

k, I'm not surprised that google won't show this. Originally telephone exchanges were plug and poke boards like looms. However lines were expensive and so many people used the same "earthed circuit". This was called "party lines". Two systems existed to identify the terminals (phones) on the lines. One system that was numeric where your number ended from 11 to 55 was two groups of rings, The other system was to use morse code as the idetifier. When I was a kid our phone number was 178M my uncles was 178R and the neighbours 178S, so when our phone rang it was two long numbers and when it was for my uncle it was short long short, and the neighbour short short short etc. There are still a few places like forest ranger stations that I know of that use this sort of system still, since it is so reliable.

but the "+1" would be nice anyway since it tells foreigners which country code to dial ;)

Yes, it is. But if you write down (650) 999-9999 I don't know if it's the US or Phillipoa....

The 1 before the area code is implied since you need to dial it anyway when calling a different area code. Yes, but in this case they are dialing the international area code before dialling the internal area code. I can see why you would add it to your phone number, to show on your business card, but I don't see why you have to dial it as well. Obs: 65 -0 is singapore :-) Regardz Colin J Davies

Does one exist? I'm getting tired of all the different ways to write phone numbers, and have decided to settle on one. So I was wondering if there already was a standard (like the ISO date format, "yyyy-mm-dd") that I should use, or if I should just pick my own?

Yes, the standard is ITU-T Recommendation E.123 (02/01)
