Carrier lookup by phone number is the ability to identify which wireless carrier a telephone number is currently assigned to. This is especially important for businesses that use SMS marketing, as texting services need to know which carriers their subscribers are on in order to send messages.

Fortunately, there are some reliable online resources that provide carrier information for free (such as SimpleTexting), or at a very low cost. In addition, a business can also hire a third-party vendor that provides this service as part of their overall SMS marketing platform solution.

In the past, it was fairly easy to determine a phone’s carrier simply by looking at its area code and 3-digit exchange. However, with the rise of number portability, that method is now less effective as it becomes more common for people to switch carriers and leave behind their old phone numbers. A mobile carrier lookup can help to find out the current provider associated with a phone number, but it may not always be accurate.

For this reason, it is important for businesses to use a reliable carrier lookup API that uses live porting data to update its database of wireless carriers and cell phones. This helps to ensure that a business is not sending messages to subscribers on invalid wireless networks, which could result in high bounce rates and costly chargebacks.

ClearoutPhone’s carrier lookup tool is an essential component of any mass messaging platform, as it allows a business to keep its database clean by rooting out invalid numbers and separating landline from mobile number data. It can also provide useful insights such as line type, timezone and more, which improves lead quality and user validation processes.
