This is the question everyone asks before getting a virtual number, and most VoIP companies dodge it. We won't.
The honest answer: mostly yes
The vast majority of services send verification codes to VoIP numbers just fine:
Works reliably:
- Most banks and financial services
- Email providers (Gmail, Outlook)
- Social media (Instagram, Twitter/X, LinkedIn)
- E-commerce (Amazon, eBay)
- Ride sharing (Uber, Lyft)
- Food delivery (DoorDash, UberEats)
- Most SaaS products
Sometimes doesn't work:
- WhatsApp (actively blocks many VoIP numbers)
- Some crypto exchanges
- Certain government services
- A few overly aggressive fraud prevention systems
Why some services block VoIP
Services block VoIP numbers to prevent fraud — bots creating thousands of accounts with virtual numbers. It's a blunt instrument that catches legitimate users in the crossfire.
The good news: this is becoming less common as VoIP numbers become more mainstream. Services that blocked them 2 years ago often work fine today.
How to maximize compatibility
- Use a real cloud number (not a temporary/disposable number) — services can tell the difference
- Keep your number active — aged numbers are trusted more than new ones
- Use it as a real number — make calls, send texts, build history on it
Jaambo's approach
We use Telnyx for our number provisioning, which provides numbers that are registered as landline or mobile types (not flagged as VoIP by most services). This gives you the highest compatibility rate possible.
Get a number and test it with your services — your first call is free.
