This guide shows how to buy a dedicated virtual number from TimelinesAI Numbers, register it in WhatsApp, and then connect the registered account to TimelinesAI. A virtual number removes the need for an extra physical SIM, but the official WhatsApp mobile app still needs a compatible phone with internet access. WhatsApp acceptance and SMS delivery are not guaranteed.
Key facts:
- WhatsApp has over 3 billion monthly active users worldwide as of 2025 (Statista)
- Over 50 million businesses use WhatsApp to connect with customers (Electroiq)
- TimelinesAI Numbers sells dedicated numbers in the United States, Canada, Puerto Rico, the United Kingdom, Sweden and the Netherlands; the live picker shows what is in stock
- Numbers is billed separately from your TimelinesAI plan; the TimelinesAI free trial does not make the number free
- Connecting the registered WhatsApp account to TimelinesAI takes one QR scan from WhatsApp's Linked devices menu

What TimelinesAI Numbers Is (and Is Not)
TimelinesAI Numbers gives you a dedicated virtual phone number that receives incoming SMS in a browser inbox and forwards them to your email. Its main use is registering a WhatsApp account without a physical SIM for that number.
It is not a SIM or eSIM data plan, not an outbound SMS tool, and not a voice-verification service. Buying a number does not register a WhatsApp account and does not connect anything to TimelinesAI. Those are separate steps, described below.
Keep the three setup steps separate
- Buy the number: sign in to Numbers with an email magic link, choose an available number, and pay through Stripe.
- Register it in WhatsApp: enter the purchased number in the official WhatsApp or WhatsApp Business app and confirm it with the SMS code that arrives in your Numbers inbox.
- Connect WhatsApp to TimelinesAI: generate a QR code in your TimelinesAI workspace and scan it from WhatsApp's Linked devices menu.
The registration SMS and the workspace QR code have different purposes. The SMS proves to WhatsApp that you control the number; the QR code links the already registered account to your TimelinesAI workspace.
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 company-owned number reduces dependence on an individual employee. Conversation history and CRM data remain available as long as the connected account, workspace access, retention settings, and integrations stay active and properly managed.
A dedicated virtual number solves both problems: it belongs to the company, it does not depend on anyone's personal phone plan, and it can be handed to a new team member without changing the number customers already know.
Step 1: Buy a Dedicated Number from TimelinesAI Numbers
1.1 — Sign in with an email magic link. Go to the Numbers sign-in page, enter your work email, and open the link you receive. No password is needed. Returning customers manage their numbers under My numbers.
1.2 — Pick a country and a number. The picker lists the countries currently in stock: the United States, Canada, Puerto Rico, the United Kingdom, Sweden and the Netherlands. Stock changes, so only what the live picker offers can be bought. Countries marked “soon” are not available yet.
1.3 — Choose monthly or yearly billing. With monthly billing, the first payment covers three months upfront plus a one-time setup fee; monthly renewals start after the prepaid period. With yearly billing, twelve months cost ten times the monthly price plus the setup fee, and later renewals are annual. Prices are in USD and vary by number and country, so the amount shown at checkout, not the monthly rate, is what you pay today.
1.4 — Pay through Stripe. After payment, the number appears in My numbers with its browser inbox. Incoming SMS show up there and are forwarded to your email.
Important: Numbers and TimelinesAI are separate subscriptions. A number does not include a workspace seat, a shared inbox or CRM plan, or WhatsApp Business Platform (WABA) messaging fees. A TimelinesAI trial does not make the number free.
If you paid but no number appears in your account, do not pay again. Contact support with the email you used and the payment time, and the team will resolve it.
Step 2: Register the Number in WhatsApp
2.1 — Install WhatsApp or WhatsApp Business. Use the official app on a compatible phone with internet access. The phone does not need a SIM for the purchased number, but you still need a phone: this route cannot be completed on a desktop alone.
2.2 — Enter the purchased number. When WhatsApp asks for a phone number, select the country code that matches the number, type the rest of the number exactly as shown in My numbers, and choose SMS as the verification method.
2.3 — Read the code in your Numbers inbox. WhatsApp sends a six-digit code by SMS. Open the number's inbox in Numbers (or check the forwarded email), then type the code into WhatsApp. Delivery time varies, so follow the timer in WhatsApp before requesting a new code.
2.4 — If WhatsApp rejects the number or the SMS does not arrive. WhatsApp acceptance is not guaranteed for any virtual number. Wait for the WhatsApp timer, try once more, and if it still fails, contact support with the exact error message shown by WhatsApp. Do not release the number to “try another one”: releasing is immediate and permanent, even during prepaid time.
This guide describes the mobile-app route. The WhatsApp Business Platform (WABA) uses a separate Meta onboarding process; buying a number does not complete Meta verification or WABA setup.

3.4 — Your number is now connected. Within seconds, your WhatsApp number appears as active in TimelinesAI. From this point, incoming and outgoing messages sync to your WhatsApp shared inbox, and your CRM integration logs conversations against the matching contact record.
Keeping the Number Active
Your number stays yours while the Numbers subscription is active. Renewals follow the billing option you chose: monthly after the prepaid three months, or annually. Manage the subscription under My numbers; the Numbers terms describe cancellation.
Releasing a number is immediate and permanent. You lose the number, and with it access to the WhatsApp account registered on it, even if prepaid time remains. Never release a number as a troubleshooting step.
Summary: The Full Flow at a Glance
Sign in to Numbers, choose a number, and pay through Stripe. Register that number in the official WhatsApp app with the SMS code from your Numbers inbox. Then generate a QR code in your TimelinesAI workspace and scan it from Linked devices. Three steps, three separate systems, and the number remains company-owned throughout.

FAQ
Does buying a number guarantee WhatsApp registration? No. WhatsApp decides which numbers it accepts, and SMS delivery can fail. Numbers are sold for WhatsApp registration, but acceptance is not guaranteed. If WhatsApp rejects your number, contact support with the exact error.
Do I still need a phone? Yes. The mobile-app route requires the official WhatsApp or WhatsApp Business app on a compatible internet-connected phone. Register the number with the SMS code first; after that, linking TimelinesAI uses a separate workspace QR code scanned from WhatsApp's Linked devices menu.
Is the number included in my TimelinesAI plan or trial? No. Numbers is a separate subscription with its own billing. A TimelinesAI plan or trial does not include a number, and a number does not include a TimelinesAI seat.
Which countries are available? Currently the United States, Canada, Puerto Rico, the United Kingdom, Sweden and the Netherlands. Stock changes; the live picker shows what can be bought right now.
What happens if I stop paying? The subscription ends and the number is released, which means losing the WhatsApp account registered on it. Keep the subscription active for as long as you need the number.
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.
