Every month, millions of people need to verify accounts with a phone number they don't want to share. I analyzed our verification data across 50 countries to find patterns most people miss.
The Dataset
Over 90 days, we tracked:
- 10,247 verification attempts across 50 countries
- 43 different services (WhatsApp, Telegram, Instagram, Discord, etc.)
- Success rates, delivery times, and cost per verification
- Provider reliability by country and time of day
Finding #1: Country Choice Matters More Than Provider
Most guides tell you to pick the cheapest provider. Our data says pick the right country first.
| Country | Avg Success Rate | Avg Cost | Avg Delivery Time |
|---|---|---|---|
| 🇺🇸 USA | 72% | $0.80 | 28s |
| 🇬🇧 UK | 78% | $0.60 | 22s |
| 🇮🇩 Indonesia | 85% | $0.15 | 18s |
| 🇮🇳 India | 68% | $0.12 | 35s |
| 🇷🇺 Russia | 82% | $0.20 | 15s |
| 🇧🇷 Brazil | 71% | $0.25 | 31s |
| 🇩🇪 Germany | 76% | $0.90 | 24s |
| 🇵🇭 Philippines | 88% | $0.10 | 12s |

Key insight: Philippines and Indonesia have the highest success rates AND lowest prices. Western countries cost 4-8x more with lower success rates.
Finding #2: Time of Day Changes Everything
We found a 23% variance in success rates based on when you verify:
Success Rate by Hour (UTC)
90% | ████
85% | ████ ████
80% | ████ ████
75% |██ ████
70% | ██
└──────────────────────────────
0 4 8 12 16 20 24
Best window: 08:00-14:00 UTC (morning in Asia, business hours in Europe)
Worst window: 22:00-04:00 UTC (overnight maintenance, carrier throttling)
Finding #3: Service Difficulty Tier List
Not all services verify equally. If you're struggling with a specific platform, check our dedicated guides:
Easy Tier (80%+ success)
- Telegram — consistently highest success
- Discord — low VoIP detection
- TikTok — accepts most number types
- LINE
Medium Tier (60-80% success)
Hard Tier (<60% success)
- Google — aggressive VoIP detection
- PayPal — carrier whitelist
- Banking apps — regulatory requirements
Finding #4: The Auto-Refund Factor
This is the metric nobody talks about. If a service doesn't auto-refund failed verifications, your real cost is:
Real Cost = Listed Price ÷ Success Rate
A $0.15 number with 60% success actually costs $0.25. A $0.30 number with 90% success and auto-refund costs exactly $0.30.
We did a deep comparison of free vs paid virtual phone numbers — spoiler: free ones have ~3% success rate.
Finding #5: Multi-Provider Routing
Services using multiple upstream providers show 12% higher success rates than single-provider services. The routing logic matters:
- Check provider inventory for the requested country + service
- Sort by historical success rate (not just price)
- Fallback to secondary provider if primary fails
- Auto-refund on timeout

Practical Takeaways
- Choose Indonesia or Philippines for budget verifications
- Verify during business hours (08:00-14:00 UTC)
- Check for auto-refund — it changes the economics completely
- Expect Google/PayPal to be hard — budget more attempts
- Multi-provider services are worth the premium
