With the introduction of cell phones, it has become easy to know the number from which you are receiving calls and texts due to the inbuilt caller IDs of the phones. With landlines, this was only possible if the landline phone had a caller ID system. This gave way to a lot of prank calls. In some situations, it is always important to know the number you are getting calls from.

Knowing what number is calling you helps in avoiding missing any important calls from anyone you know, only when you know whose number it is. But in cases, you don’t know whose number it is and if it is a cell phone number, it can be a bit difficult to find out. Here are a few ways to lookup a cell phone number when you get calls from unknown numbers.

• Using a search engine:  Try looking up for the number on a search engine. It can be any search engine. The result will show you if the number has been mentioned by the user in any blog or entered on any other website as a part of registering the number. This way to lookup a cell phone number may sound vague, but you never know what results turn up.
• Using social media platforms:  Social media has become the choice of several people to interact with people, and these sites often have users who mention their cell phone numbers on their profile. Looking up a variety of such websites should help you, if the person whose number you are looking for, is present on any of these social media websites and has mentioned it in their profile.
• Using online cell phone lookup directories:  There are several directories online that have a collection of cell phone numbers where you can lookup a cell phone number. The number you are looking for may or may not be in one directory, but since there are several such directories present online, you may just find the owner of the number.

When you want to lookup a cell phone number, you will have to use online services since physical phone directories don’t usually list cell phone numbers and mainly list only landline numbers.
