Quick answer: A WhatsApp messaging limit caps how many different people your business can message outside a customer service window in a moving 24-hour period. According to Meta, a new business portfolio starts at 250. You can move to 2,000 by verifying your business or by sending 2,000 messages to unique numbers in 30 days, and above that the limit rises automatically if your message quality is high.
Many teams hit this limit on the first big campaign. The messages queue, fail, or only reach part of the list, and nobody warned them. Knowing the rules in advance lets you plan the ramp-up. If you are new to the platform, our guide to what the WhatsApp Business API is and how it works in India is the place to start.
What the limit actually counts
Meta's documentation says the limit is on the number of distinct WhatsApp users a business can message outside a customer service window in a moving 24-hour period. Three details matter:
- It counts people, not messages. Sending ten messages to one person counts as one.
- It applies outside the service window. Replies to customers who have written to you in the last 24 hours do not use it up. See our guide to the WhatsApp customer service window.
- It is shared. The limit is set for the whole business portfolio and shared by every phone number in it, so one busy number can use up the allowance of the rest.
The tiers
- 250: the default for a newly created portfolio.
- 2,000: reached by completing a scaling path.
- 10,000, 100,000 and unlimited: reached through automatic scaling.
How to get from 250 to 2,000
Meta lists scaling paths. Completing any one of them starts a review:
- Verify your business with Meta.
- Have your partner verify it, if a partner onboarded you.
- Send 2,000 delivered messages outside customer service windows to unique numbers within 30 days, using high-quality templates.
After you complete a path, Meta reviews your message quality. If it approves, the limit rises to 2,000 straight away and you are told by email and a developer alert. If it denies, the limit stays and the alert suggests alternatives, such as sending more high-quality messages or verifying your identity.
How the limit grows after 2,000
Above 2,000, scaling is automatic. Meta's documentation says it raises the limit by one level, within six hours, when you have sent high-quality messages across all your numbers and templates and used at least half of your current limit in the last seven days. In short, you move up by sending good messages to enough people.
Why quality matters
Both routes depend on message quality. Meta's business messaging policy, last updated 23 September 2026, says users can block or report businesses and that, based on that feedback, WhatsApp's systems may limit how many messages or calls a business can send. Meta's pages we read do not explain a quality rating scale in detail, so this article does not describe one.
What you can control:
- Send only to people who opted in. Our guide to WhatsApp opt-in rules explains how.
- Write templates that match what the person expects. See our guide to WhatsApp message templates.
- Make stopping easy and honour every request.
- Do not blast the full list in one go. Send in stages and look at how people react.
Planning a campaign around the limit
- If your list is bigger than your limit, split it across several days. The limit is a moving 24 hours, so a 2,000 limit allows about 2,000 people a day.
- Start with your most engaged contacts. Good response early helps your quality.
- Do not move everything to a second phone number. The limit is shared across the portfolio.
- Verify your business early. It is one of the routes to 2,000, and it is useful for other reasons.
