WhatsApp Business API Messaging Limits Explained
Short answer: WhatsApp limits how many different people a business can start conversations with in a day. The limit starts low and rises as your account is verified, as you send more, and as customers respond well. Quality matters: many blocks and reports can lower the limit or restrict the number. Meta changes these rules from time to time, so read the current figures in Meta's documentation.
This page explains the concepts, not exact numbers. For the numbers, see Meta's WhatsApp documentation. For the wider picture, see the WhatsApp Business API guide.

|---|---|---|
| Messaging limit (tier) | The number of unique people you can start business conversations with in a rolling day | Business verification, volume sent, quality |
| Quality rating | A signal of how recipients react to your messages | Blocks, reports, opt-in quality, relevance of templates |

How to keep your limit healthy
- Message only people who opted in. See opt-in and consent.
- Send relevant, expected messages and avoid long gaps followed by bursts.
- Make it easy to opt out so people do not block you instead.
- Verify your business to unlock higher limits. See business verification.
- Ramp up volume gradually, and start with your most engaged contacts.
What to do if you hit a limit
Spread the campaign over more days, prioritise the most important recipients, and use SMS or voice for the rest. Check errors against WhatsApp API error codes, and see fallback routing for sending the remainder another way.
Messaging limit questions
What is my WhatsApp messaging limit?
It is shown in your account's tools and depends on verification, volume and quality. Check the current value in your dashboard or Meta's tools.
How do I raise my messaging limit?
Verify your business, send to opted-in people, keep quality high and increase volume steadily.
Does the limit count replies to customers?
The limit concerns business-started conversations. Replies within the customer service window are handled differently.
Why did my quality rating drop?
Usually from blocks and reports. Review who you message, how often and with what content.
Are the limits the same for every provider?
The limits come from Meta, not the provider. A provider can help you monitor and manage them.
