10 Best Second Phone Number Apps in 2025

A second phone number app protects your privacy by allowing you to manage personal and business conversations independently. Second phone number apps offer fairly adaptable options, whether you require a temporary line for short-term use or a second phone number for your business. In 2025, leading providers such as SecondLine Number, Google Voice, and Burner will provide temporary numbers, VoIP calls, call forwarding, and voicemail. Whether for business, vacation, or online safety, these business phone number applications offer a secure and simple way to keep organized.

Second phone number apps make it easy to:

Maintain privacy by avoiding giving out your primary number
Separate work and personal calls/texts
Protect yourself from spam and scams.
Conduct business more professionally.

Why Do You Need a Second Phone Number?

Before diving into the best apps, let’s understand why a second number is beneficial:

01. Privacy Protection

Sharing your primary number online or with strangers can lead to spam calls, scams, and unwanted messages. A second number keeps your real number private.

02. Business & Professional Use

Without a second phone, freelancers, entrepreneurs, and remote workers can present more professionalism by using a dedicated second phone number for business.

03. Online Dating & Classifieds

A second number keeps people from seeing your personal contact information when you use dating apps like Tinder or post ads on Craigslist.

04. Travel & International Use

When travelling, a local virtual number helps you stay connected without expensive roaming charges.

05. Temporary Use for Verification

Many services call for phone confirmation. A disposable second number locks your main number rather than your actual number, this is where burner phone apps shine.
