What this means

Reaching the next tier

Once a portfolio is at 2,000, Meta raises it automatically. Two things have to be true at the same time: message quality is high across every business phone number and template, and the business used at least half of its current messaging limit in the last 7 days.

When both hold, the portfolio limit goes up one level within 6 hours. That is why a slow trickle of messages keeps an account stuck: the volume half of the test never gets met.

How to get from 250 to 2,000 →

Short answer: a WhatsApp messaging limit is the maximum number of unique WhatsApp users you can deliver messages to, outside a customer service window, in a moving 24-hour period. It counts people, not messages. A new business portfolio starts at 250, and the ladder from there is 2,000, then 10,000, then 100,000, then unlimited. The limit is set at the business portfolio level and shared by every phone number in that portfolio, so one number can eat the whole allowance. Throughput is a separate cap: up to 80 messages per second by default.

Last updated August 2026. Tiers, scaling paths and rate limits on this page were read from Meta's WhatsApp Business Platform messaging limits documentation and Cloud API overview on 16 August 2026.

There is no 1,000 tier, and "Tier 1" is not a thing anymore

This is the single most repeated error about WhatsApp messaging limits. A lot of provider help centers and agency blog posts still describe a ladder of Tier 1 at 1,000 unique customers, Tier 2 at 10,000 and Tier 3 at 100,000, and tell you that business verification lifts you straight to 1,000. That was the old model. Meta's current documentation lists the ladder as 250, 2,000, 10,000, 100,000 and unlimited, with no 1,000 step and no Tier 1 or Tier 2 naming.

The distinction matters when you are budgeting a launch. If you plan a 10,000-person campaign believing verification hands you 1,000 recipients a day, you will build a 10-day schedule. The real first step up is 2,000, which is a five-day schedule, and the step after that is automatic rather than something you apply for. Getting this wrong at the planning stage is how teams end up explaining a stalled campaign to a client.

The second stale detail is on the API side. The messaging_limit_tier field that older tutorials tell you to query has been deprecated. Meta's own note on the messaging limits page is blunt about it: the field "used to return a business phone number's messaging limit" and you should request whatsapp_business_manager_messaging_limit instead.

WhatsApp messaging limit tiers, and what unlocks each one

Every figure below is a count of unique WhatsApp user phone numbers you can deliver to outside a customer service window, inside a moving 24-hour window, across the whole business portfolio.

Messaging limit	Who is on it	How you move up from here
250	Every newly created business portfolio starts here.	Complete one of the three scaling paths below. This is the only step you take deliberately.
2,000	Portfolios that finished a scaling path and passed Meta's quality analysis.	Automatic from here. High quality plus using at least half your limit in 7 days.
10,000	Steady senders with a clean quality rating.	Automatic, same two criteria, one level at a time.
100,000	High-volume programs.	Automatic, same two criteria.
Unlimited	The top of the ladder.	Nothing further to unlock. Quality still governs whether you stay here.

Limits are calculated and set at the business portfolio level and shared by all business phone numbers in that portfolio. If you run several numbers, read the guide to multiple WhatsApp Business numbers, because one number can consume the entire portfolio allowance before the others send anything.

How to increase your WhatsApp messaging limit from 250 to 2,000

Meta gives three routes out of the starting tier. You only need one of them. After that, further increases happen on their own.

Verify your business

The fastest route for most companies, and free. Meta checks your legal business details against official documents. Our Meta business verification walkthrough lists the document types that are accepted.

Have your partner verify it

If a solution partner or tech provider onboarded you, they can complete verification on your behalf. Worth asking about before you start the paperwork yourself.

Send your way there

Deliver 2,000 messages outside customer service windows to unique WhatsApp users within a 30-day moving period, using templates with a high quality rating. Slow, but it needs no paperwork.

Finishing a path does not by itself raise the limit. Meta then analyzes your message quality and either approves or denies eligibility for automatic scaling. On approval the limit moves to 2,000 immediately, you get an email and a developer alert, and a business_capability_update webhook fires carrying the new figure.

On denial an account_alerts webhook fires instead, and the alert_type tells you what to do next. There are three of them worth knowing: INCREASED_CAPABILITIES_ELIGIBILITY_DEFERRED and INCREASED_CAPABILITIES_ELIGIBILITY_FAILED both point you back at the send-2,000-messages route, and INCREASED_CAPABILITIES_ELIGIBILITY_NEED_MORE_INFO asks you to verify your identity first. If you are not receiving these at all, your endpoint is probably not subscribed properly, which the WhatsApp webhook setup guide covers.

Messaging limits, throughput and pair rate limits are three different caps

Most confusion about "the WhatsApp message limit" comes from collapsing three separate controls into one. They are set at different levels and they fail in different ways.

Cap	What it limits	Set at	The number
Messaging limit	Unique people you can start a conversation with, outside a customer service window, per moving 24 hours.	Business portfolio	250 to unlimited
Throughput	How fast you can push messages out, in aggregate.	Business phone number	80 per second by default, upgrades available
Pair rate limit	How often you may message the same person.	Sender and recipient pair	1 message every 6 seconds

The pair rate limit is the one that bites during testing. Meta puts it at 1 message every 6 seconds to the same WhatsApp user, which works out to roughly 10 messages a minute or 600 an hour, and going past it returns error code 131056 until you are back inside the allowed rate. Bursting is tolerated but borrowed: you may send up to 45 messages in a 6-second burst, after which you have to wait the time it would have taken at the normal rate. Meta's own example is that a burst of 20 needs about a two-minute wait before you message that user again.

If a send fails on this, Meta's guidance is to retry after 4^X seconds, starting at X of 0 and adding 1 after each failure. Any sender worth using implements that backoff for you. Other codes you may see during a large campaign are collected in the WhatsApp error codes reference.

How to check your current WhatsApp messaging limit

In the interface

Open WhatsApp Manager and go to Account tools, then the Messaging limits panel. The current limit for the business phone number is displayed there.

This is the version to check before a campaign, because it reflects any change Meta made in the last few hours.

Over the API

Call the WhatsApp Business Phone Number API and request the whatsapp_business_manager_messaging_limit field. The response comes back in the form TIER_250.

Do not reach for messaging_limit_tier. It is the field most tutorials still show, and it is deprecated.

One version note that matters if you parse webhooks: the capability update carries max_daily_conversations_per_business on webhooks v24.0 and newer. The older max_daily_conversation_per_phone field applies to v23.0 and earlier and Meta has it running only until February 2026, so anything still reading it needs updating.

What actually happens when you hit the limit

Sends to new people start failing once the portfolio has reached its unique-recipient count for the moving 24-hour window. Because the window moves rather than resetting at midnight, capacity comes back gradually as older sends age out, which is why a stalled campaign often resumes in dribs rather than all at once.

Two things are worth knowing before you panic. First, the limit counts unique recipients, not messages, so five messages to one customer consume one slot. Second, it applies to messages sent outside a customer service window. Replies inside an open 24-hour window are governed by the customer service window rules rather than by your messaging tier, though from 1 October 2026 Meta begins charging for service messages, which changes the economics rather than the caps.

The durable fix is quality, not volume. Meta gates every automatic increase on message quality across all your numbers and templates, so a portfolio that gets blocked or reported will stop climbing regardless of how much it sends. The quality rating guide explains what moves that score, and clean opt-in collection is the largest single input to it.

Who runs into the messaging limit

Teams launching a first campaign

A list of 20,000 against a fresh 250 limit is an 80-day schedule. Almost nobody discovers this before the launch date is already promised.

Agencies running several brands

Numbers sharing one business portfolio share one allowance. Two clients sending the same morning can starve each other without either seeing why.

Retailers with seasonal peaks

A tier that carries normal weeks will not carry a promotion. Because scaling needs sustained volume, the ramp has to start weeks before the peak.

Anyone migrating providers

The messaging limit tier carries over with the number, but template quality ratings restart, and quality is half of the auto-scaling test.

Developers testing in a loop

Repeated sends to a single test number hit the 1-per-6-seconds pair limit long before the daily cap, and error 131056 looks alarming the first time.

Businesses stuck at 250

Usually because nobody completed verification and the account never sends enough to qualify the other way. It is a paperwork problem, not a technical one.

Frequently asked questions

How many messages can I send per day on WhatsApp Business API?

It depends on your tier, and the figure counts people rather than messages. A new business portfolio can start conversations with 250 unique WhatsApp users in a moving 24-hour period. The ladder above that is 2,000, 10,000, 100,000 and unlimited. Replies inside an open customer service window do not count against it.

Is there a limit on WhatsApp messages?

Yes, three of them. A messaging limit caps how many unique people you can message first each day. Throughput caps how fast you can send, at 80 messages per second by default. A pair rate limit caps how often you can message one individual, at 1 message every 6 seconds. They apply at the same time.

How do I increase my WhatsApp messaging limit?

To get from 250 to 2,000, complete one of three scaling paths: verify your business, have the partner who onboarded you verify it, or deliver 2,000 messages outside customer service windows to unique users within a 30-day moving period using high-quality templates. Above 2,000 every increase is automatic.

What is WhatsApp Tier 1?

It is an obsolete label. Older documentation described Tier 1 as 1,000 unique customers a day, and many third-party guides still repeat it. Meta's current messaging limits documentation has no Tier 1 naming and no 1,000 step. The ladder is 250, 2,000, 10,000, 100,000 and unlimited.

Does the WhatsApp messaging limit count messages or people?

People. Meta defines the messaging limit as the maximum number of unique WhatsApp user phone numbers you can deliver to in a moving 24-hour period. Sending one person six messages uses one slot out of your allowance, not six. This is why the cap rarely blocks conversational support and often blocks broadcasts.

Is the messaging limit per phone number or per account?

Per business portfolio. Meta calculates and sets the limit at the portfolio level and shares it across every business phone number inside that portfolio. One number can consume all of the portfolio's messaging capability in a given period, which catches out agencies running several brands from one portfolio.

How long does it take to increase the messaging limit?

Once a portfolio sits at 2,000 and meets both automatic scaling criteria, the limit rises one level within 6 hours. Getting off the 250 starting tier is the slower part, because it depends on how quickly business verification clears or how long you take to deliver 2,000 messages.

What is WhatsApp error 131056?

It means you exceeded the pair rate limit by messaging the same WhatsApp user too often. The allowance is 1 message every 6 seconds to that person, about 10 a minute. The error clears once you are back inside the rate. Meta suggests retrying after 4 to the power of X seconds, increasing X on each failure.

Why is my WhatsApp messaging limit not increasing?

Usually volume, not quality. Automatic scaling requires that your business used at least half of its current messaging limit in the last 7 days, alongside high quality across numbers and templates. A portfolio sending well under half its allowance will sit at the same tier indefinitely, however clean its record is.

Does the messaging limit apply to customer replies?

No. The limit governs messages delivered outside a customer service window, meaning conversations you start. Replying to someone who messaged you inside the open 24-hour window is not counted against the tier. From 1 October 2026 those service messages become chargeable, but they still do not consume your daily allowance.

Knowing the cap is step one. Sending inside it is step two.

A campaign that respects the daily tier, paces itself under the pair rate limit and backs off on errors is the difference between a list that lands and an account that stalls. WaBulkSend will schedule bulk WhatsApp campaigns that stay inside these limits automatically.
