How to Get a Second Phone Number for WhatsApp (Without a New SIM)

To get a second WhatsApp number without a new SIM, rent a real mobile number online (for example from SMS Hallo, from $1.80/month), enter it in WhatsApp with the + and country code, and type in the 6-digit code that arrives in your online inbox. Keep the number rented for as long as you use the account so you can always re-verify it.

Why people use a second WhatsApp number

Many people keep work and personal chats apart, sell on marketplaces, run a small business, or simply don't want to hand their personal number to strangers. WhatsApp ties every account to one phone number, so a second account needs a second number.

You don't need a second phone or SIM card. WhatsApp Business and the regular WhatsApp app can both run on one phone, and each can use its own number.

What you need

A real mobile number that can receive SMS or calls — WhatsApp sends a 6-digit code to verify it.

Access to that number for as long as you use the account. WhatsApp may ask you to verify again when you change phones or reinstall the app.

Step by step

1. Choose a country. Pick the country your contacts or customers expect, or the one you live in.

2. Rent a number. On SMS Hallo, open the country, pick a number and choose a plan. It is active immediately.

3. Start WhatsApp registration. Enter the number in international format: the + sign, the country code, then the number.

4. Choose SMS. The verification code arrives in your SMS Hallo inbox within seconds. If WhatsApp offers a voice call instead, you can answer it on your number too.

5. Enter the 6-digit code and finish setting up your profile.

6. Turn on two-step verification in WhatsApp (Settings → Account → Two-step verification) for extra security.

Keep your account safe long term

The most common mistake is letting the number expire. If someone else later gets that number and verifies it, they could take over the account. Renew the number before it ends, or switch on auto-renew.

Add an email address in WhatsApp's two-step verification settings so you can recover your PIN.

Frequently asked questions

Can I use the same number for WhatsApp and WhatsApp Business?

No. Each WhatsApp account needs its own number. You can use one number for WhatsApp and a second number for WhatsApp Business on the same phone.

How long does the WhatsApp code take to arrive?

Usually a few seconds. It appears in your SMS Hallo inbox and the code is highlighted so you can copy it with one tap.

What happens if the code doesn't arrive?

Wait for the timer and request the code again, or choose the voice-call option. If the number still doesn't work for you, replace it free with another number within 7 days, or get a 100% refund.
