SMSFlashStep-by-step guide to getting a virtual number for WhatsApp, receiving the 6-digit code online, and keeping the account safe afterwards.
Why use a separate number for WhatsApp?
WhatsApp ties every account to a phone number, and that number is visible to everyone you chat with. Many people want a second profile that does not expose their personal SIM: a WhatsApp Business line for a small shop, a profile for a community group, a test account for a developer building a chatbot, or a number to use while travelling.
A virtual number for WhatsApp is a real mobile number that receives the WhatsApp verification SMS for you. The code shows up in your SMSFlash account in the browser, so you do not need a second phone or a second SIM card.
How to get a WhatsApp number in 5 steps
- Create a free SMSFlash account and top up from $5 with USDT (BEP20 or TRC20).
- Search for WhatsApp in the service list and pick a country with numbers in stock. The price is shown before you pay.
- Copy the number and paste it in WhatsApp (choose the matching country code in the app).
- Tap Next and wait. The 6-digit code appears in your active numbers, usually within a minute.
- Enter the code in WhatsApp and finish the profile set-up.
Which country works best for WhatsApp?
There is no single best country. WhatsApp checks many signals, and acceptance varies day by day. A practical approach is to start with a country that has good stock and a mid-range price, and switch if the first number is refused. Many users prefer a number from the country they live in or travel to, because WhatsApp may ask for a new code if your location changes a lot.

If WhatsApp says "this number is banned" or the code never arrives
Some numbers in any pool have been used before or are restricted by WhatsApp. If WhatsApp refuses the number, or no SMS arrives after 2 to 3 minutes, cancel the order in your SMSFlash account. The full price goes back to your balance and you can try another number or country. If the timer runs out with no code, the refund is automatic. Our OTP troubleshooting guide has more tips.
Keeping the account: one-time vs rented number
A one-time activation is enough to register. But WhatsApp can ask for a new SMS code later, for example when you install it on a new phone. If that number is gone, you could lose access. To avoid this:
- Turn on two-step verification in WhatsApp (Settings, Account, Two-step verification) and add a recovery email.
- Keep the app installed on one device and back up chats.
- If the account is important, use a rented number for a longer period instead of a one-time activation.
Use it responsibly
Use your virtual number for legitimate needs such as privacy, business separation and testing. Do not send spam, bulk messages or anything that breaks WhatsApp’s terms of service; WhatsApp bans such accounts quickly, and numbers are not refunded after a code is received.

Frequently asked questions
Can I use a virtual number for WhatsApp Business?
Yes. WhatsApp Business verifies a number the same way as the normal app, by SMS or call. Buy a WhatsApp number, enter it in WhatsApp Business and read the code in your SMSFlash account.
How long do I have to receive the WhatsApp code?
A one-time activation stays active for about 20 minutes. If no code arrives in that time, the price is refunded to your balance automatically.
Will I be charged if WhatsApp does not send the code?
No. You can cancel before a code arrives for a full refund to your balance. You only pay for numbers that received a code.
Can I receive WhatsApp codes on the same number again later?
One-time numbers are meant for one code. If you expect WhatsApp to ask again, rent a number for days or months where available, and turn on two-step verification.
