Connecting WhatsApp to your practice raises a lot of questions about numbers, Meta requirements, billing, and Meta's evolving platform rules. The answers below cover what you need to know before and after you connect.
Do I need a Meta Business Account to use WhatsApp? Yes. To use WhatsApp, you need a Meta (Facebook) Business Account in Meta Business Manager, because the WhatsApp Business API is managed and verified by Meta. You do not need a Facebook Page for messaging itself, but you must have a Meta Business Account so Meta can verify your business identity, manage your WhatsApp Business Account (WABA), authorize sending and receiving on your number, and store your business information. Without this setup, your number cannot be approved for the WhatsApp Business API and cannot be connected.
How do I create a Meta Business Account? Visit https://business.facebook.com/ and click "Create account." Enter your business name, your name, and a business email, then submit. Confirm the verification email Meta sends you. In Meta Business Settings, open Business Info and add your legal business address, website, and phone number, then save. If verification is required for WhatsApp API approval, open Security Center in Business Settings, click "Start Verification," and upload the requested documents (such as a registration certificate or utility bill). Meta's verification can take from a few hours to a few days. During WhatsApp setup in your account, you will log in with Meta, choose your verified Business Account, select or create a WABA, add your number, and complete the SMS or call verification.
Can I use my existing WhatsApp number? You cannot directly use an existing personal or business WhatsApp number until it is migrated or connected through the WhatsApp Business API via Meta. You can use your existing number if it is not currently linked to WhatsApp Messenger or the WhatsApp Business app, or if you are willing to delete your WhatsApp account from the app to free up the number for API use, complete the WhatsApp API onboarding, and have Meta verify and approve the number under your Business Manager (WABA). To free up the number, open WhatsApp, then go to Settings > Account > Delete my account.
When can I not use my existing number? You cannot use your number if it is still active on the standard WhatsApp or WhatsApp Business app, or if you want to use the same number on both your phone and the API at the same time. Meta does not allow this. A number can only be connected to one platform: either the app or the API, not both.
What are my options for using an existing number? Option 1 is to migrate your existing number: delete your WhatsApp or WhatsApp Business account from the phone app, verify the same number during API setup, and once approved all messages are managed inside your account. Note that after the number is connected to the API you can no longer use it in the mobile app. Option 2 is to use a new number for the API while keeping your existing WhatsApp number active on your phone for personal use, which is often the easiest and safest option if you do not want to lose your current app chats.
Can I use my number on both the WhatsApp Business Platform and the WhatsApp Business App at the same time? Yes, using the WhatsApp Coexistence feature, which lets businesses use their existing WhatsApp Business App account alongside advanced CRM tools powered by the WhatsApp Cloud API.
Will I lose my data after migrating my WhatsApp number to the WhatsApp Business Platform? Yes, you will lose all data associated with WhatsApp after migration. Meta does not allow data transfers between the platforms, so it is highly recommended to back up your data before migrating.
How do I back up my data before migrating my WhatsApp number? Open WhatsApp, go to Settings > Chats > Chat backup, and follow the prompts to back up your data to your preferred location, such as Google Drive or iCloud.
Why did a message fail because the user's phone number is part of an experiment? Since June 14, 2023, roughly 1% of WhatsApp users will not receive marketing template messages from any business unless one of the following exists between the customer and the business: an open customer service window, an open marketing conversation, or an open free-entry-point conversation. If you send a marketing template to a customer in the experiment group, the message will not be sent and you will not be billed for it, since no conversation was created.
What do "WhatsApp conversation charges" refer to if WhatsApp is free for personal use? While the WhatsApp app and WhatsApp Business app are free, businesses using the WhatsApp Business API to communicate with customers at scale are subject to conversation charges. These charges apply when a business sends notifications to customers via the WhatsApp Business Platform, especially if the customer has not responded within the last 24 hours. The cost depends on the customer's country code, and these charges are billed to you at actual cost with no additional surcharge.
What is changing with WhatsApp pricing starting July 1, 2025? WhatsApp is moving from per-conversation to per-message pricing, so you are charged for each template message sent rather than for a full conversation. Utility templates sent within a 24-hour service window are free. More frequent pricing updates may follow; refer to WhatsApp's official Pricing Update for details.
Can I still send marketing template messages to U.S. numbers? Starting April 1, 2025, marketing template messages cannot be sent to U.S. phone numbers (those starting with +1). This is a temporary restriction aimed at improving the customer experience. Utility and service messages are still allowed. If a user replies to a marketing message, a 24-hour service window opens during which you can send messages freely.
What message template types can I send? You can send approved templates that are text-only, media-based (images, documents), interactive (buttons like Call or Visit Website), location-based, authentication (one-time password), and multi-product messages. All templates must be pre-approved and sent using your access token.
What happens if I exceed per-user messaging limits? Starting March 3, 2025, WhatsApp tracks how users engage with your marketing templates, and if a user is not engaging you will be allowed to send them fewer messages. Attempting to send beyond the limit may return Error Code 131049 (marketing limit reached for this user) or Error Code 131050 (user opted out of marketing messages). These errors are returned in the message webhook. Do not keep resending after an error; wait and try again later.
What should I do if my messages are not being delivered? Confirm the recipient's number is valid and active on WhatsApp, ask the recipient to update their app to the latest version and accept the latest WhatsApp Terms of Service, and if marketing limits apply, use a utility template instead, since utility templates are more reliable in those cases.
What is Meta's Frequency Capping update, and who does it affect? Meta introduced Frequency Capping to limit how many marketing messages a person can receive from any business in a given period, reducing spam and improving the user experience. It works on a first-come, first-served basis: marketing messages are delivered until the limit is reached, and any beyond that are not delivered. Frequency Capping only applies to marketing messages sent to users with Indian phone numbers (+91 country code). For a WhatsApp Business Account with multiple phone numbers, the cap is based on the total number of messages an individual user receives from any business, not from one specific business.
Which messages are exempt from Frequency Capping? Frequency Capping only applies to promotional and marketing template messages that require opening a new conversation. It does not apply to session messages (support messages within existing customer service interactions) or Click to WhatsApp Ads (conversations initiated by users clicking on WhatsApp ads).
What are the benefits of verifying my Facebook Business Manager account? Once Meta verifies your Facebook Business Manager account, you can initiate unlimited business conversations on WhatsApp.
What can I do while my Facebook Business Manager account is not yet verified? While verification is pending, you can initiate up to 250 business conversations in a 24-hour rolling window, respond to customer-initiated conversations without restriction, and have two WhatsApp business numbers in an unverified account.
What happens if my business verification is unsuccessful? You can continue using your WhatsApp business number with the same restrictions that apply before verification: 250 business conversations in a 24-hour period and unrestricted responses to customer-initiated conversations.
How do I request verification for my Facebook Business Manager account? To request verification, provide proof of your legal entity and access to the business. Detailed instructions are available in Meta's guide on verifying your business in WhatsApp Business Manager.
What are the recommended best practices to improve deliverability? Send messages only to customers who have explicitly opted in, segment your contact list to send targeted messages, personalize recommendations based on customer behavior and purchase patterns, emphasize quality over quantity so every message adds value, and engage in two-way conversations to keep customers interested.
Will unsubscribing from WhatsApp affect my phone numbers and templates? No. Unsubscribing does not affect your WhatsApp phone numbers or templates. When you resubscribe, all numbers and templates are restored exactly as they were before.
Can I send or receive messages while my WhatsApp subscription is inactive? No. Messages cannot be sent or received while the subscription is inactive. However, all data, including phone numbers and templates, remains intact and is restored upon resubscription.
Will my workflows and automations linked to WhatsApp templates be preserved during the unsubscribed period? Yes. All workflows and automations linked to your WhatsApp templates remain intact and function as before once you resubscribe. Resubscribe promptly to avoid disruptions in your messaging workflows.
What should I do if I face issues after resubscribing to WhatsApp? If your phone numbers or templates do not appear after resubscribing, reach out to our support team for assistance.
What is the Shared Account Model, and when do I need to migrate? Meta is phasing out the older On Behalf Of (OBO) onboarding model in favor of the Shared Account Model. New onboarding became available March 24, 2025, the OBO flow was retired September 30, 2025, and Meta began automatically migrating remaining accounts on October 1, 2025.
What does "Last onboarding failed! This WABA is already onboarded at this Location ID" mean? This means the WhatsApp Business Account (WABA) you are trying to onboard is already connected to another account, as shown in the error message. If you want to onboard this WABA to a different account, first disconnect it from the current one, then proceed with onboarding it to the account you want.
