As AI tools and online platforms continue to grow rapidly, phone number verification has become a standard requirement for account creation and security. However, a common and frustrating barrier stands in the way: many of these services require a US phone number for account verification. Whether you’re a developer, a creative professional, or a tech enthusiast living outside the United States, this verification wall can block your progress.
This blog explains how a US second phone number helps phone verification, and how apps like TrueNumber make the process simple, private, and reliable.

How to Get Started with TrueNumber for AI Tools & Online Accounts
- Download & Sign Up: Get the TrueNumber app from the App Store or Google Play. Create your account.
- Choose Your US Number: Select your preferred US area code or choose from available numbers.
- Verify and Use: The number is instantly active. Use it the next time you sign up for an AI tool, social media account, or any online service that asks for a US phone number. Enter the verification code you receive in the TrueNumber app.
- Stay Organized: Use your TrueNumber consistently for all your “digital identity” needs to keep your accounts secure and separate.
Best Practices for Using a Second Number
-
Treat It Like a Real Number: While it’s a second number, it’s tied to your important accounts. Keep the app installed and accessible.
-
Check for Long-Term Needs: If you plan to use a crucial service (like a primary OpenAI API account) for years, consider a long-term number subscription to avoid the hassle of changing numbers later.
-
Combine with a Secure Email: For maximum security and organization, create a dedicated email address to use alongside your TrueNumber when signing up for new accounts.
As AI tools become part of everyday work and life, phone number verification is no longer optional. Using your personal number everywhere isn’t always safe or practical.
A US second phone number offers a simple solution—protecting your privacy while improving verification success. With TrueNumber, you get a reliable US number that works seamlessly for AI tools and online accounts.
