Is It Safe and Legal?

Using a virtual number to receive WhatsApp OTP is perfectly legal in most countries, including Vietnam. You are simply using a temporary number for verification, just like a prepaid SIM. WhatsNum does not sell numbers for fraud, spam, or illegal activities. We recommend using the number only for the intended verification and not for long-term use. Your payment is anonymous via USDT, so your privacy is protected.

How long does the Vietnam virtual number last?

You have 20 minutes to receive the WhatsApp OTP. After that, the number expires and cannot be reused. If you need another verification, purchase a new number.

What if I don’t receive the OTP?

If you don't get the SMS within 20 minutes, report it in your dashboard and we will issue a free replacement number. Success rate is over 95% for WhatsApp Vietnam.

Can I use the number for other apps?

Yes, the same number can receive OTP for Telegram, Viber, Signal, etc., but only during the 20-minute window. We recommend focusing on one app per purchase.
