Have you ever wondered whether the phone number called you is a landline or a cell phone? Perhaps you’re curious about the number type before returning a missed call or texting the number. 

Whatever the reason is, distinguishing between a cell phone and a landline can be helpful in various situations. 

In this article, we’ll explore the different methods that can help you determine whether a number is a cell phone or a landline.

How Can You Tell a Cell Phone Number from a Landline?

There is no apparent difference between a cell phone and a landline number. Both typically follow the same format: an area code and a 7-digit local number. 

In the early days of cell phones, numbers could be differentiated by looking at the first digits of the area codes. 

Numbers 9, 8, 7, or 6 were more commonly associated with cell phones, while 2, 3, 4, or 5 were frequently used for landlines. However, this approach is like a guessing game today, as phone number allocation varies by region and can change over time. 

Relying solely on the first digits of a number’s area code may not provide accurate results. To better distinguish a cell phone and a landline by phone number, it’s best to rely on tools or services designed specifically for this purpose.

Using Phone Number Validators

One tool that you can use to determine whether a phone number is a landline or a cell phone is a phone number validator. 

Thanks to the capabilities of the internet, we now have access to online tools such as phone validators that can analyze phone numbers and provide information that a user needs.

These validators work by accessing vast databases containing phone number allocation and other information about the number. Below are some of the most effective phone validators in the market. 


One popular phone number validator is the Phone Validator. It offers a straightforward interface where you can input the number you want to check. 

Apart from determining the phone line type, PhoneValidator offers additional details like the phone’s location and even the owner’s name and address, if available. 

It’s like having a private investigator at your fingertips, empowering you with essential insights about the number you’re investigating.


Similar to the Phone Validator, RealPhoneValidation allows you to verify and identify the type of phone number quickly. The tool offers up to 5 number validation requests, and a free trial requires you to sign up to receive 100 free validations. 

You can also submit a batch of phone numbers with an account, which makes it very handy for businesses.

The results show the phone type (cell phone, landline, VoIP), if the number is active and in service, and the carrier associated with the number. 


This is another alternative service worth considering. SearchBug’s phone validator service offers results including phone type, carrier name, detailed location, and area code information. 

You only have to input a phone number, select a service type, and click “Verify.” You will find your results by clicking on “Sample Report.” The site is a pay-per-use service. However, new users get their first search for free.

Phone number validators are best for quick searches and allow you to take the proper approach in your communications. However, if you prefer a much instant, real-time context on what type of number is calling you, Caller ID apps are a good alternative.

Using Caller ID Apps

Caller ID apps are mobile applications that display caller information when receiving an incoming call. These apps work by cross-referencing the incoming phone number with their databases to provide you with the relevant information.

Several caller ID apps for Android and iOS devices can help indicate whether the number is a cell phone or a landline. Also, you can manually enter a phone number to discover all the necessary information.

Additionally, these apps can warn you about suspicious callers and help you avoid scammers and spam calls

Some popular caller ID apps include Truecaller, CIA, and Caller ID, all offering free versions. 

Using Reverse Phone Lookup Tools
