The menace of mobile phone theft had become a serious problem in the country that had not only inconvenienced many people but also endangered lives and businesses. It can be also common to receive some phone numbers while you are not around, which are registered as missed calls. You call these numbers up and at times, you are not able to reach the caller and at some other times, you wish for a National Phone Registry. Alas, your wish does come true! With Phone Number Registry, you can not only find out where the call originates from but also the city and the Zip code of the source of the call! Sounds interesting, that is not all! One can find out from Phone Registry the owner of the number as well as his or her address as well! Such a great service will be a boon for those tracking to find out the unknown numbers in their mobile or cellular phones. It will be a cinch to know the ‘who’, ‘what’ and ‘where’ of the caller of the number we wish to find out! And for the why if he does call you, you have to be sure you get through to him and ask directly!. The primary goal of this Registry is to determine the frequency of major malformations seen after use of atypical antipsychotics during pregnancy compared to what is seen among women who do not take such medications during pregnancy.
