Nowadays, phones are used mostly for communication. So it is essential to have all the phone numbers that we need all the time so that we can contact people whenever we need them. But we are not always aware of all contact numbers. Dealing with unknown numbers is difficult. Phone books nowadays do not have all the numbers. They mostly contain landline numbers of government departments and business organizations, but not the cell phone numbers. So they are mostly useless to find phone numbers because statistics say that 95% of the population uses cell phones, 46.5% use only cell phones.

There are many ways to look up for a number online.

Internet search engines
You may find phone numbers on popular search engines such as Google, Yahoo etc., and alternative search engines that are specially designed for only information about people. You can enter as much information you know about that person in the search bar such as the name, age, address, job etc., and there is a good chance that you might find his/her number.

Social media
To find phone numbers, social media may be the easiest method.

Apps
There are different apps and tools on the Internet that can provide full information about the searched person. Truecaller is one of them. It searches deeply in the network and even finds information about more than one similar person.

Servers
There are websites that work as servers to find phone numbers. It is very easy to find someone there; you only need to know the name, location or zip code. And the best part is that all these services are totally free.

• Whitepages
  With around 50 million users per month, Whitepages is a digital identity verification platform. It offers free searches for people and companies. To use it, you have to go to their main page and insert the name of the person, country, city or zip code. The location and the telephone number will appear on the screen immediately.
• ZabaSearch
  If a person gives any of his personal information anywhere online even once, ZabaSearch captures the data and secures it forever. You can find people’s names, number, address and other information too.
• True People Search
  Another free digital verification platform, True People Search helps to find phone numbers, address, email id, etc.

Online directories
There are some online directories that specialize in phone numbers. Not only can you find someone’s number, but you can also find the whereabouts of some unknown number that keeps calling you. National Cellular Directory is one of the top companies. Their service is not free, but you can find phone numbers for free during their happy hours.

Lastly, it can be said that not all numbers can be found. If it were easy, then people would have misused the opportunity. You have to have the patience to find the phone number you want.
