Since October 7, 2025, it is set per business portfolio and shared by all its phone numbers: it starts at 250, rises to 2,000 after you complete a scaling path (such as verifying your business) and from there grows on its own to 10,000, 100,000 and unlimited, as long as your messages are high quality and you use at least half of your limit within 7 days.<\/p>\n\n\n\n<p>Below: what counts toward the limit, how to move up, how quality fits in and how to check everything via API.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What counts toward the limit and what doesn&#8217;t<\/h2>\n\n\n\n<p>The limit measures <strong>unique recipients<\/strong>, not messages. And it only counts people who receive a message <strong>outside<\/strong> the 24-hour customer service window, that is, messages the business starts with a template.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Situation<\/th><th>Counts toward the limit?<\/th><\/tr><\/thead><tbody><tr><td>Template sent to a customer who hasn&#8217;t written in the last 24 hours<\/td><td>Yes, 1 recipient<\/td><\/tr><tr><td>Three templates to the same customer in the same 24-hour period<\/td><td>Yes, but only 1 recipient<\/td><\/tr><tr><td>Free-form reply to a customer who wrote 2 hours ago<\/td><td>No<\/td><\/tr><tr><td>Template sent as a reply while the window is open<\/td><td>No, because it&#8217;s inside the window<\/td><\/tr><tr><td>Attempt to send a paused template<\/td><td>No (the API rejects it without counting)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The customer service window is explained in the article on the <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-24-hour-customer-service-window\/\">WhatsApp 24-hour window<\/a>. In practice, inbound support barely touches the limit; what runs into it are high-volume notifications and campaigns.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The limit tiers<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Tier<\/th><th>Unique users in 24 hours<\/th><th>How to get there<\/th><\/tr><\/thead><tbody><tr><td>Starting<\/td><td>250<\/td><td>Newly created portfolio<\/td><\/tr><tr><td>2,000<\/td><td>2,000<\/td><td>Complete a scaling path and pass Meta&#8217;s review<\/td><\/tr><tr><td>10,000<\/td><td>10,000<\/td><td>Automatic scaling<\/td><\/tr><tr><td>100,000<\/td><td>100,000<\/td><td>Automatic scaling<\/td><\/tr><tr><td>Unlimited<\/td><td>No cap<\/td><td>Automatic scaling<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">The limit belongs to the portfolio, not the number<\/h3>\n\n\n\n<p>Before October 2025, each number had its own limit. Now the value is calculated and set at the business portfolio level, and all its numbers share the same quota. Two consequences:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A new number starts with the portfolio&#8217;s limit.<\/strong> There&#8217;s no need to &#8220;warm up&#8221; a number from scratch.<\/li>\n\n\n<li><strong>One number can use up the whole quota.<\/strong> If the billing number sends to 9,000 customers in a portfolio with a 10,000 limit, 1,000 are left for the sales number in the same 24 hours.<\/li>\n\n<\/ul>\n\n\n\n<p>During the migration, Meta set each existing portfolio&#8217;s limit to the highest limit among its numbers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to get from 250 to 2,000<\/h2>\n\n\n\n<p>Meta offers three scaling paths. Completing one is enough:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Verify your business<\/strong> in Meta&#8217;s business portfolio.<\/li>\n\n\n<li><strong>Have your business verified by a partner<\/strong>, when you were onboarded by a provider that offers partner-led verification.<\/li>\n\n\n<li><strong>Deliver 2,000 messages outside the customer service window<\/strong>, to unique recipients, within a moving 30-day period, using high-quality templates.<\/li>\n\n<\/ol>\n\n\n\n<p>Once you complete a path, Meta analyzes your message quality and approves or denies eligibility for automatic scaling.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Approved:<\/strong> the limit goes to 2,000 right away. You get an email, a developer alert and the <code>business_capability_update<\/code> webhook with <code>max_daily_conversations_per_business<\/code> set to the new limit (on webhooks v24.0 and newer).<\/li>\n\n\n<li><strong>Denied:<\/strong> the limit stays the same, and the <code>account_alerts<\/code> webhook gives the reason in <code>alert_type<\/code>.<\/li>\n\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th><code>alert_type<\/code><\/th><th>What to do<\/th><\/tr><\/thead><tbody><tr><td><code>INCREASED_CAPABILITIES_ELIGIBILITY_DEFERRED<\/code><\/td><td>Deliver 2,000 messages outside the window, to unique recipients, in 30 days, with high-quality templates<\/td><\/tr><tr><td><code>INCREASED_CAPABILITIES_ELIGIBILITY_FAILED<\/code><\/td><td>The same 2,000-message path<\/td><\/tr><tr><td><code>INCREASED_CAPABILITIES_ELIGIBILITY_NEED_MORE_INFO<\/code><\/td><td>Verify your identity with Meta or follow the 2,000-message path<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Business verification is usually the fastest path for companies whose registration and documents are in order (in Brazil, that means the CNPJ, the national company registration number). The step-by-step is in <a href=\"https:\/\/vectalk.com.br\/blog\/en\/meta-business-verification-whatsapp\/\">Meta business verification<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Automatic scaling: from 2,000 to unlimited<\/h2>\n\n\n\n<p>From 2,000 up, Meta raises the limit one tier at a time, without a request, when two conditions are met:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>you send high-quality messages across all the portfolio&#8217;s numbers and templates;<\/li>\n\n\n<li>in the last 7 days, you used at least half of your current limit.<\/li>\n\n<\/ul>\n\n\n\n<p>With both conditions met, the increase happens within 6 hours. For a portfolio at 10,000, that means having sent to at least 5,000 unique users outside the window at some point in the last week.<\/p>\n\n\n\n<p>Anyone who wants to reach 100,000 by a specific date (Black Friday, a payment due date, an enrollment campaign) needs to plan the ramp-up in advance. Each step requires real use of the previous one. The <a href=\"https:\/\/vectalk.com.br\/blog\/en\/black-friday-whatsapp-marketing\/\">Black Friday on WhatsApp<\/a> guide has a send calendar built around this.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Don&#8217;t confuse the limit with throughput or per-user limits<\/h2>\n\n\n\n<p>Four different mechanisms can block a send. Each has its own cause and error code:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Mechanism<\/th><th>What it limits<\/th><th>Value<\/th><th>Error<\/th><\/tr><\/thead><tbody><tr><td>Messaging limit<\/td><td>Unique users outside the window in 24 hours, per portfolio<\/td><td>250 to unlimited<\/td><td>\u2014<\/td><\/tr><tr><td>Throughput<\/td><td>Messages per second, per number<\/td><td>80\/s by default; up to 1,000\/s with an automatic upgrade<\/td><td><code>130429<\/code><\/td><\/tr><tr><td>Pair rate limit<\/td><td>Too many messages to the same user in a short time<\/td><td>No published value<\/td><td><code>131056<\/code><\/td><\/tr><tr><td>Marketing per-user limit<\/td><td>Marketing templates a user receives from all businesses<\/td><td>Dynamic, based on the user&#8217;s engagement<\/td><td><code>131049<\/code><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The upgrade to 1,000 messages per second requires a portfolio with an unlimited limit, a number that has already reached 100,000 unique users outside the window in 24 hours, and a quality rating of medium or high. The details are in <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-api-rate-limit-throughput\/\">WhatsApp API rate limits and throughput<\/a>. For <code>131049<\/code>, Meta advises waiting at least 24 hours before resending to the same user; repeated retries within that period can block further attempts to that user for up to 24 hours. The article on <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-error-131049-marketing-limit\/\">error 131049<\/a> goes deeper.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quality rating<\/h2>\n\n\n\n<p>Meta rates message quality based on what happened over the last 7 days, with more weight on the most recent messages. The signals named in the documentation are blocks, reports, mutes, archives and the reasons users give when they block you.<\/p>\n\n\n\n<p>There are two ratings you should track:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Rating<\/th><th>Where it shows up<\/th><th>Values<\/th><\/tr><\/thead><tbody><tr><td>Number quality<\/td><td>The number&#8217;s <code>quality_rating<\/code> field and WhatsApp Manager<\/td><td><code>GREEN<\/code> (high), <code>YELLOW<\/code> (medium), <code>RED<\/code> (low)<\/td><\/tr><tr><td>Template quality<\/td><td>The template&#8217;s <code>quality_score<\/code> field<\/td><td><code>GREEN<\/code>, <code>YELLOW<\/code>, <code>RED<\/code>, <code>UNKNOWN<\/code><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>High-traffic numbers can change quality within short intervals, sometimes within minutes. The meaning of each color is detailed in <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-phone-number-quality-rating\/\">WhatsApp phone number quality rating<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What changed: low quality no longer lowers the limit<\/h3>\n\n\n\n<p>Until October 2025, a number with &#8220;Flagged&#8221; quality for 7 days lost a limit tier. Meta has removed that state: today, if a number&#8217;s quality drops, <strong>the limit is not reduced<\/strong>.<\/p>\n\n\n\n<p>That doesn&#8217;t make quality irrelevant. It still decides three things:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Whether the limit goes up.<\/strong> Automatic scaling requires high-quality messages across all numbers and templates.<\/li>\n\n\n<li><strong>Whether the template stays live.<\/strong> A template that reaches <code>RED<\/code> is paused for 3 hours, then 6 hours, and the third time it&#8217;s disabled.<\/li>\n\n\n<li><strong>Whether the business faces enforcement.<\/strong> Meta&#8217;s enforcement policy says that excessive user complaints can lead it to limit the business or offboard it from WhatsApp. The article on a <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-api-number-banned\/\">banned WhatsApp API number<\/a> details those measures.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">What stalls your growth<\/h2>\n\n\n\n<p>The most common reasons the limit stops rising, or messages stop going out, are predictable:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A list without opt-in.<\/strong> Contacts who weren&#8217;t expecting the message block and report.<\/li>\n\n\n<li><strong>Generic messages.<\/strong> Meta recommends avoiding open-ended welcome or introduction messages and personalizing the content.<\/li>\n\n\n<li><strong>High frequency.<\/strong> Several templates a day to the same contact pull the rating down and hit the pair rate limit.<\/li>\n\n\n<li><strong>A cold audience at volume.<\/strong> Sending to the whole base at once, without testing how a smaller group reacts.<\/li>\n\n\n<li><strong>Using less than half the limit.<\/strong> Without usage, there&#8217;s no automatic scaling.<\/li>\n\n\n<li><strong>Marketing templates classified as utility.<\/strong> Besides recategorization, this triggers its own restrictions. See the guide to <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-api-message-templates\/\">WhatsApp API message templates<\/a>.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to check limit and quality via API<\/h2>\n\n\n\n<p>On the Graph API, the portfolio&#8217;s current limit is in the <code>whatsapp_business_manager_messaging_limit<\/code> field, which can be read on the business portfolio, on the WhatsApp Business account or on the phone number. The old <code>messaging_limit_tier<\/code> field is deprecated.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"language-bash\">curl 'https:\/\/graph.facebook.com\/v26.0\/PHONE_NUMBER_ID?fields=whatsapp_business_manager_messaging_limit' \\\n  -H 'Authorization: Bearer META_TOKEN'\n\n# Response\n{ \"whatsapp_business_manager_messaging_limit\": \"TIER_250\", \"id\": \"PHONE_NUMBER_ID\" }<\/code><\/pre>\n\n\n\n<p>With Vectalk, number data comes from <code>GET \/api\/phone-numbers<\/code>, with the number resolved from the instance token. The documentation shows the <code>fields<\/code> parameter and a response with <code>quality_rating<\/code> and the throughput level:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"language-bash\">curl 'https:\/\/apis.vectalk.com.br\/api\/phone-numbers?fields=id,display_phone_number,verified_name,quality_rating' \\\n  -H 'Authorization: Bearer YOUR_INSTANCE_TOKEN'<\/code><\/pre>\n\n\n\n<p>So you don&#8217;t have to poll, handle the webhooks. Vectalk forwards the events in Meta&#8217;s format:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>business_capability_update<\/code>: the portfolio&#8217;s new limit in <code>max_daily_conversations_per_business<\/code> (values <code>2000<\/code>, <code>10000<\/code>, <code>100000<\/code> or <code>UNLIMITED<\/code>);<\/li>\n\n\n<li><code>phone_number_quality_update<\/code>: changes to the number&#8217;s quality status;<\/li>\n\n\n<li><code>account_alerts<\/code>: scaling denials and next steps;<\/li>\n\n\n<li><code>message_template_quality_update<\/code> and <code>message_template_status_update<\/code>: template rating and pauses.<\/li>\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Planning a send within the limit<\/h2>\n\n\n\n<p>For high-volume sends, track unique recipients over the last 24 hours before calling the API and push the rest to the next day. A sketch:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"language-javascript\">const LIMIT = 2000;               \/\/ read it from the business_capability_update webhook\nconst WINDOW_MS = 24 * 60 * 60 * 1000;\n\nasync function canSend(waId) {\n  const since = new Date(Date.now() - WINDOW_MS);\n  const alreadyReceived = await db.sends.exists({ wa_id: waId, outside_window: true, sent_at: { $gte: since } });\n  if (alreadyReceived) return true; \/\/ the same recipient doesn't count twice\n  const unique = await db.sends.countDistinct(\"wa_id\", { outside_window: true, sent_at: { $gte: since } });\n  return unique &lt; LIMIT * 0.95; \/\/ margin for sends from other numbers in the portfolio\n}<\/code><\/pre>\n\n\n\n<p>Remember to add up all the portfolio&#8217;s numbers in the count. The article on <a href=\"https:\/\/vectalk.com.br\/blog\/en\/whatsapp-bulk-messaging-official-api\/\">bulk messaging with the official API<\/a> covers queues, pacing and segmentation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Can I ask Meta to raise my limit manually?<\/h3>\n\n\n\n<p>The documentation only describes the scaling paths to reach 2,000 and automatic scaling from there. The practical route is to verify your business and use the limit with well-received messages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does adding more numbers raise the limit?<\/h3>\n\n\n\n<p>No. The limit belongs to the portfolio and is shared by all its numbers. A new number simply starts using the same quota.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does replying to customers use up the limit?<\/h3>\n\n\n\n<p>No. The limit only counts recipients of messages outside the customer service window. Replies within the 24-hour window are excluded.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">My quality dropped to yellow. Will I lose my tier?<\/h3>\n\n\n\n<p>Under the current rules, no. A quality drop doesn&#8217;t reduce the limit, but it can block further increases and lead to template pauses. Review audience, frequency and content before your next send.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Scale your sends with Vectalk<\/h2>\n\n\n\n<p>With Vectalk, you connect your numbers through Meta&#8217;s Embedded Signup and run all your accounts with one token, receiving the limit and quality webhooks in the format of the official documentation. Billing works with a monthly fee plus a prepaid balance: Vectalk puts its own line of credit on your number, each delivered message is deducted from your balance and no card is registered with Meta.
