Free phone numbers for SMS verification
Claim a free temporary number, request your OTP, and read the code here — no account required. Free numbers share a public pool with limited apps. When you need reliability, privacy, or 1000+ services, switch to paid numbers in one click.
Get a free number
Pick a supported app, choose a country, claim a number, then send the verification SMS. We poll for your OTP automatically.
Your free sessions
Keep this tab open while you request the code on the app. Codes appear here when the SMS arrives. Sessions expire after 30 minutes and numbers return to the free pool.
Free vs paid numbers
Free numbers are great for a quick test. Paid numbers are built for real accounts, privacy, and volume.
| Free numbers | Paid private numbers | |
|---|---|---|
| Apps available | Few apps in the free pool (often only a handful) | 1,000+ services ready to verify |
| Success rate | Shared public lines — mixed results | Private routes with higher delivery success |
| Privacy & control | Shared pool — others may have used the line | Dedicated activation under your account |
| Daily volume | No daily free claim cap (shared public pool) | Unlimited paid activations with your balance |
| API & automation | Manual browser use only | Full reseller API, webhooks, rentals |
| Refunds | Best-effort public pool | Automatic refunds when OTP does not arrive |

Free numbers FAQ
Are these really free temporary phone numbers?
Yes. You can claim free temporary numbers and receive SMS OTPs for apps in the free pool without creating an account. Shared public lines mean success rates vary.
Why is my app missing from the free list?
The free pool only includes a small set of apps with free stock. Paid numbers support 1000+ services including WhatsApp, Telegram, Google, Instagram, TikTok, and more.
How many free numbers can I get per day?
Proxnum does not apply a daily free claim cap. Free lines are still a shared public pool with limited apps — switch to paid when you need reliability, privacy, or premium services.
Do I need to log in?
No login is required for free numbers. Create an account when you are ready to buy paid private numbers, rentals, or API access.
Why did my OTP not arrive?
Free lines are shared public numbers and can fail more often. Paid private numbers offer higher success rates, automatic refunds, and better routing.
When should I switch to paid numbers?
Switch when you need a specific app (WhatsApp, Telegram, Google, etc.), higher success rate, privacy, rentals, or API automation. Many customers try free today and buy paid tomorrow.
