Dev Tool of the Week: A "Phone Number Creator" API for Non-VoIP Verification

As developers, we all hit that wall when testing auth flows or managing multiple accounts: VoIP blocks.

Twilio and Google Voice numbers get flagged instantly by modern security filters (Cloudflare, etc.) because they are easily detectable virtual lines.

I built a solution called the Rent Number on LegitSMS. It provisions Real Physical SIMs that completely bypass VoIP detection, allowing you to rent a dedicated mobile number for testing or long-term account management.

The Workflow: Designed for stability over speed.

Step 1: Select Region: Choose from 50+ countries including USA, UK, and Netherlands.

Step 2: Define Duration: Unlike "one-time" OTPs, this creates a persistent session. You can hold the number for 1 day, 1 week, or 3 month.

Step 3: Unlimited Inbound SMS: You can hit the same number with unlimited verification requests—perfect for testing retries, setting up multi-platform 2FA, or validating complex auth sequences.

Key Technical Specs:

Dedicated SIM Slots: These are private rentals. No one else shares the line during your session.

Persistence: Our "Smart Restore" capability allows you to retrieve message history even if a session is closed, ensuring you don't lose access to a test account.

Carrier Grade: Sourced directly from major telecom carriers to ensure high deliverability rates.

If you need a reliable, persistent line that actually works on difficult sites, check it out.
