Why You Need a Dedicated Number for Business WhatsApp
Using your personal mobile number for business WhatsApp creates two problems. First, you cannot separate work messages from personal ones. Second — and more critically — your business loses access to those conversations the moment an employee leaves.
A dedicated number solves both. It stays with the company, not the person. Your conversation history, contacts, and CRM data remain intact regardless of team changes.
The fastest way to get a dedicated number today — without waiting for a new SIM card or going through a carrier — is through Zadarma, a virtual phone provider with mobile numbers available in over 100 countries.
Step 1: Choose the Right Number Type on Zadarma
Not every Zadarma number type works for WhatsApp registration. You need to pick carefully.
WhatsApp requires a number that can receive SMS. This rules out standard VoIP or landline-only numbers. On the Zadarma platform, look specifically for:
- Mobile numbers — these are attributed to a mobile code for a specific country and many support SMS reception
- Numbers listed under the “Mobile + SMS” filter in the number catalog
Important: Zadarma is transparent about this. Their own documentation notes that WhatsApp prioritizes mobile and landline numbers for registration, and SMS reception must be confirmed before you buy. Always verify the “SMS enabled” flag on the number listing before purchasing.
Which country should you choose?
Pick a country where your business operates or where your customers are based. If you serve clients globally, a UK, US, or German mobile number are popular choices. The country code will appear in your WhatsApp profile, so choose one that makes sense for your brand.

Step 2: Sign Up on Zadarma and Purchase Your Number
Here is the full purchase flow from scratch.
2.1 — Create your Zadarma account

Go to zadarma.com and click Sign Up. Enter your email address, existing phone number, and create a password. You’ll receive a confirmation email and SMS code. Verify them before proceeding.
2.2 — Navigate to Virtual Phone Numbers

Once logged in, go to Virtual Phone Numbers section. You will land on the virtual number catalog.
2.3 — Filter for Mobile + SMS numbers

On the number catalog page:
- Select your target Country from the dropdown
- Click the “Mobile + SMS” tab to filter out numbers that cannot receive SMS
- Review the results — you will see the monthly fee and any one-time connection fee
2.4 — Confirm SMS is enabled before buying

Before adding a number to your cart, click “More info” on the listing. Confirm that the number details explicitly state SMS reception is supported. This is the single most important check — do not skip it.
2.5 — Complete the purchase
Add the number to your order and proceed to checkout. Zadarma supports payment by card and several other methods. After payment, the number will appear in your account under My Numbers.
Tip: Zadarma recommends prepaying for a year in advance to keep your number active without interruption. An expired number means losing your WhatsApp account access.
2.6 — Check your number is verified

In the My Numbers section, click the Settings button on your new number. The status should show as Enabled. Until a number is verified, it cannot receive SMS. If it shows as pending, contact Zadarma support via their online chat.
Step 3: Register Your Zadarma Number on WhatsApp
Now that your number is active and SMS-enabled, you will register it as a WhatsApp account.
3.1 — Download WhatsApp or WhatsApp Business on a spare device
You need to install WhatsApp on a physical device for the initial registration. Use a spare smartphone, a tablet, or a secondary device.
3.2 — Enter your Zadarma number during setup
Open WhatsApp or WhatsApp on your device. When prompted to enter a phone number:
- Select the correct country code matching your Zadarma number
- Enter the Zadarma number exactly as it appears in your Zadarma dashboard (without the country code prefix)
- Tap Next and then choose “Send SMS” when asked how to receive your verification code
3.3 — Retrieve the verification code from Zadarma
WhatsApp will send a 6-digit code via SMS to your Zadarma number. To find it:
- Log in to your Zadarma account
- Go to Services → SMS → Message History
- The verification code will appear in the inbox — usually within 30–60 seconds
3.4 — Enter the code in WhatsApp
Type the 6-digit code into WhatsApp. Your account is now active on this number.
Step 4: Connect Your New WhatsApp Number to TimelinesAI
Your WhatsApp account is live. Now connect it to TimelinesAI to sync messages with your CRM.

FAQ
Does Zadarma guarantee WhatsApp registration? No — and they say so openly. WhatsApp requires mobile or landline numbers for registration. Zadarma’s mobile numbers with SMS enabled are compatible with WhatsApp in most cases, but success depends on the specific country and number. Always filter for “Mobile + SMS” numbers and verify the SMS-enabled status before purchasing.
Can I use the Zadarma number without a physical device? You need a physical device to scan the initial WhatsApp QR code during setup. After the account is created and linked to TimelinesAI, you can manage all messages from the TimelinesAI dashboard — you do not need to keep the device nearby.
What happens if my Zadarma subscription lapses? If you stop paying for the number, it will be released. This means you would lose access to the associated WhatsApp account. Keep your Zadarma subscription active — Zadarma recommends paying annually to avoid gaps.
Do I need WhatsApp Business or regular WhatsApp? Either works with TimelinesAI. WhatsApp Business adds a dedicated business profile, auto-replies, and quick messages — making it the better choice for customer-facing use.
How many WhatsApp numbers can I connect to TimelinesAI? You can connect multiple numbers across different team members or departments. TimelinesAI manages them all from a single dashboard, which is useful when scaling your team’s WhatsApp communications.
