    Our Carrier lookup updates are in real time or near real-time when you send a query to us. Perhaps you have a list of older opt-in phone numbers that you would like to re-verify the identity of their carrier or network operators. Or you would like to use Email to SMS or Email2SMS (sending SMS using emails) method to send SMS to mobile users who agree to receive such, or you would like to provide a convenient feature to the users by automatically identifying their mobile operator. Perhaps you have a landline phone numbers list that need to be updated.

    Yes, we provide a simple HTTP API for the purpose of Number Portability check/carrier lookup. The HTTP GET or POST info is found inside your login account. Single or multiple phone numbers can be included in a single query. The response is in simple XML similar to REST. There is also a manual interface for you to enter a telephone number to retrieve the carrier lookup result. Simply register an account now.

    We can run your list and provide the carrier name or result next to each number in your list. The list of numbers need to be in a text file with one phone number per row. There is a small handling fee that you can pay for in your account. You also need to buy enough credits for us to run the list for you. Then just email us with your username and your list. We strive for a 48-hours completion time, but it's not a guarantee. (We are not responsible for any incorrect number or errors in your list).

  5. How are credits decremented (charged)?
    The lookup result or reply can be a positive identity of a carrier (such as a 6-digit number), or unknown. You are charged for any of these 2 possible results. A lookup that returns unknown means the network in which the phone number resides is unrecognized or perhaps the telephone number is nonexistant. This can be the case when the network is not supported or listed in our Carriers Coverage page.
