Using International Formatting for Numbers

We've discussed how to access the phone numbers in your Contacts list quickly. But those tips are useful only when you can use the phone numbers stored in the Contacts list. In particular, if you are a traveler, a number in your Contacts list might need a prefix when you call from another city or country. If that is the case, you cannot use any of the Contacts list features on your phone a huge bummer, and a huge loss of productivity. One of the most important tips to speed up your dialing is to store properly formatted phone numbers, which are accepted in all areas you travel to, in the Contacts list in the first place.

Most wireless network operators allow you to use shortened phone numbers. In the U.S., you can typically just dial a seven-digit number to reach a local phone number. However, it is a bad idea to put seven-digit numbers in your Contacts list, especially if you travel a lot. For instance, the number 5551212 reaches different people in New York City and in San Francisco. At the very least, you need the 10-digit number, which includes the 3-digit area code, to dial anywhere in the U.S.

The situation is even more confusing if you travel to other countries. Ten-digit U.S. numbers will not work in the UK or in Germany. The best way to store phone numbers in your Contacts list is to use the international phone number format. To conform to the international phone number format, you simply need to add a +1 in front of a 10-digit U.S. phone number. Therefore, the phone number 5555551212 would be +15555551212. It doesn't route any differently if you call or send a Short Message Service (SMS) message to a number in that format from your home calling areathe operator knows what to do with it.
