Phone Number

When you’re ready to use your app for a production use case, you need to use your own phone number to send messages to your users. When choosing a phone number, consider the following:

• If you want to use a number that is already being used in the WhatsApp customer or business app, you will have to fully migrate that number to the business platform. Once the number is migrated, you will lose access to the WhatsApp customer or business app. See for information.
• We have a set of rules regarding numbers that can be used in the platform. .
• Once you have chosen your phone number, you have to add it to your WhatsApp Business Account. See How to Connect Your Phone Number to Your WhatsApp Business Account.

Opt-In

You are required to obtain user opt-in before sending proactive business-initiated messages. See Get Opt-In for WhatsApp for more information.

Pricing & Payment Methods

Businesses are charged per conversation, which includes all messages delivered in a 24 hour session. The first 1,000 conversations each month are free. If you want to send more than 1,000 conversations, you need to add a credit card to your account.

For more information see Pricing and Payment Methods.

Send More Messages

To send more business-initiated messages, you need to use message templates. WhatsApp message templates are specific message formats that businesses use to send out notifications or customer care messages to people that have opted in to notifications.

Before sending a message template, you need to create one or you can use one of our pre-approved templates. Check this guide to learn how to send message templates.

Incoming messages are unlimited, but there are limits for outgoing messages. See Messaging Limits for more information on messaging tiers.
