    I've had my iphone for about a month now, and I seem to be having problems with my caller id settings. When I get incoming phone calls from certain US area codes, the caller id reads the number as an international call. For example, if the caller's phone number is (310) 625-8633, the iphone displays the number as "+31 06258633".

    Am I missing some simple setting to correct this problem?

    Thanks for the help!

    No, I don't see how this solves the problem at all. This only happens with certain US area codes, and others it works fine. The area codes are formatted properly and yet I still get these funny formats on incoming calls.

    Settings > General > International > Region Format > United States

    Should fix the formatting issue.

    Thanks for the response. Yes, I tried that a long time ago, so that's not the problem. It seems to be a glitch with the iphone software or something.

    I have the same problem but only with incoming text messages from certain people. The number comes in as +1 (xxx) xxx-xxxx. The +1 throws off the address book and it doesn't display the person's name. It's only happened with 2 people and it's a recurring problem with the same two people.

    Just you have "International Assist" turn on? If you do, try turning it off. Not sure if will make any difference but that "feature" could have code that might cause a problem like this.

    Thanks for the suggestion on International Assist, but, no, I've had it turned off consistently, and I still get the funny international formatting on incoming calls.

    Completely wild stab in the dark...

    Could it be that all the numbers that are exhibiting this problem are using VOIP, and perhaps that VOIP provider isn't sending the CID data correctly?

    What happens when each of the numbers calls someone else - is the CID info correct then?

    I must give you a 10 for thinking outside the box, but, alas, no that's not the case. I think I just have a bad phone or something.
