For developers

Four calls from zero to a verified code

List the countries, list the services, request a number, then poll for the code. No SDK to install — it is plain HTTP, so anything that can make a request can drive it.

Read the API docs

request a number
# 1. request a numbercurl-s'https://api.pvapins.com/user/api/get_number.php   ?customer=YOUR_API_KEY&app=APP_NAME&country=COUNTRY_NAME'# 2. poll for the code — back off 3s, 5s, 8scurl-s'https://api.pvapins.com/user/api/get_sms.php   ?customer=YOUR_API_KEY&number=NUMBER&app=APP_NAME'→ code delivered to your dashboard and the API
How it works

From sign-up to verified, in four steps

Your personal SIM stays out of it.

Create an account

An email and a password. No phone number and no identity documents.

Pick country and service

Choose from 200+ countries, then the app you need verified.

Receive the code

The OTP lands in your dashboard, and on the API if you are polling it.

Verify

Enter the code. Under No-Code, No-Pay you are only charged when one arrives.

Who it's for

Built for privacy and for scale

Privacy-conscious individuals

Verify social, messaging, and email accounts without handing over your real number.

Developers and QA engineers

Drive OTP flows from the REST API and test verification paths in staging without burning real SIMs.

Travellers and remote teams

Get a local number in another country without buying a physical SIM to do it.

Small businesses

Handle region-specific verifications for client accounts and internal tools from one balance.

Frequently asked

Quick answers

PVAPins rents temporary and longer-term virtual phone numbers for receiving SMS verification codes without using your personal SIM. It covers 200+ countries and works with WhatsApp, Gmail, Telegram, Instagram, and hundreds of other platforms.

Create a free account, pick a country and the app you want to verify, then choose a number. Your OTP appears in your dashboard within seconds. No SIM card and no identity documents.

A non-VoIP number comes from a real cellular carrier. Many platforms reject internet-based VoIP numbers, so non-VoIP routes deliver more reliably on stricter services such as banking apps and major social networks.

Wait for the timer to finish, then cancel. Your balance is returned under the No-Code, No-Pay policy. If it keeps happening, switch country or route, choose a non-VoIP number, or contact support on Telegram.

Yes. Rentals run for 72 hours, 7 days, or up to 30 days. A rented number stays in your dashboard for repeat codes, password resets, and re-verification prompts.

Crypto (Bitcoin, USDT), Binance Pay, cards, Payeer, Skrill, Payoneer, DOKU, GCash, and region-specific options including Nigeria and South Africa cards.

Yes. A REST API covers the whole flow: list countries, list services, request a number, and poll for the code. Endpoint reference and copyable samples are in the API documentation.

You verify accounts without handing over your personal SIM, and you pay with crypto or a card, whichever you prefer. All data handling follows the PVAPins privacy policy.
