Meta Ads Error Decoder

Cryptic Facebook or Instagram ad error? Find it here to understand what went wrong and exactly how to fix it.

100 Graph API

Invalid Parameter

You've passed an invalid parameter to the Meta Graph API. This could mean a missing required field, an improperly formatted JSON payload, or trying to use a field that does not exist on the node you are targeting.

190 Graph API

Invalid OAuth Access Token

Your Meta User Access Token or System User Token is invalid, has expired, or the user changed their password.

17 Graph API

User Request Limit Reached

Your app or account is making too many API calls in a short window. Meta enforces strict rate limits to maintain platform stability.

2 Graph API

Service Unavailable

Meta's Graph API is experiencing a temporary disruption. This is an internal server issue on Facebook's end.

368 Graph API

Temporarily Blocked for Policies

Meta has temporarily blocked your action because your app or account engaged in behavior that violates their developer policies, or you performed an action deemed 'spammy' too quickly.

1885016 Account & Billing

Ad Account Disabled

Your ad account has been flagged and suspended for violating Meta's Advertising Policies. All delivery pauses immediately.

1487390 Account & Billing

Billing Threshold Reached

Your account hit its billing threshold and Meta attempted to charge your card, but the charge failed. Consequently, all campaigns have been halted.

1487734 Account & Billing

Unsettled Account

The account has an unpaid invoice from a previous billing cycle. Meta restricts creating new campaigns or turning active ones on until the balance is cleared.

2446077 Account & Billing

Account Spend Limit Reached

You hit your lifetime Account Spend Limit. This is a manual safety cap you or an admin previously placed on the entire Business Manager or Ad Account.

1443141 Creative & Copy

Ad Rejected - Policy Violation

Your recently launched ad was rejected by the review algorithm for violating Meta's Advertising Standards (e.g., adult content, misleading claims, or unacceptable business practices).

1815148 Creative & Copy

Image Too Small

The picture you've selected for your image ad or carousel doesn't meet the minimum pixel dimensions required for the chosen placements.

1487042 Creative & Copy

Video File Format Not Supported

You tried uploading a video type that Meta doesn't know how to process, or the file size is wildly over the maximum limit.

1885065 Creative & Copy

URL Not Accessible

The destination URL (Landing Page) attached to your ad is currently throwing a 404 error, redirecting in a loop, or taking too long to load during the approval process.

1815802 Creative & Copy

Headline Too Long

Your primary text or headline has breached the character limits allowed for a specific placement (like the Right Column or Instant Articles).

2446252 Targeting & Audiences

Audience Too Small

Your targeting parameters are mathematically too restrictive. The custom audience size falls below Meta's absolute minimum threshold required to initiate learning/delivery (usually < 100 people).

2650020 Targeting & Audiences

Lookalike Audience Not Ready

You applied a Lookalike Audience to your ad set, but Meta's backend is still crunching the data on the seed audience. Ads won't spend until compilation finishes.

1885002 Targeting & Audiences

Invalid Custom Audience Value

You tried to attach a Custom Audience to the `included_custom_audiences` array that mathematically doesn't exist, was deleted by another user, or belongs to an unlinked Business Manager.

3858082 Targeting & Audiences

Detailed Targeting Expansion Required

Based on current Meta constraints (like targeting housing, employment, or credit scopes), you physically cannot turn off Detailed Targeting Expansion or you are requesting extremely narrowed attributes.

1487836 Campagin Structure

Bid Too Low

Your manual manual cost cap or bid limit is drastically lower than the floor threshold required to actually enter an active auction against competitors.

1885025 Campagin Structure

Daily Budget Too Low

The daily budget provided across the campaign (CBO/ABO) or ad set doesn't meet the daily minimum requirement for the currency your ad account operates in (e.g. less than $1 USD).

1885183 Campagin Structure

Optimization Goal Invalid

You picked an optimization goal (like 'Purchases' or 'Value') that fundamentally clashes with the chosen Campaign Objective (like 'Brand Awareness').

1487435 Campagin Structure

Promoted Object Missing

You declared a conversion campaign, but you totally forgot to tell Meta *what* they are optimizing for. An Ad Set needs a specific Pixel Event or App Event ID attached to it.

4 Graph API

Application Request Limit Reached

Your application (not just the user) has exceeded the app-level API call rate limit. This is different from error 17—this limit applies to all users of your app collectively.

10 Graph API

Permission Denied

Your app or access token doesn't have the required permission to perform this action. The token may be valid, but it lacks the specific scope needed for the endpoint you're calling.

200 Graph API

Requires Extended Permission

You're trying to perform a write operation (like creating or modifying an ad) but your access token only has read-level permissions. The specific extended permission for this action hasn't been granted.

1 Graph API

Unknown Error

Meta's servers encountered an unexpected internal error that doesn't map to a specific known error code. This is Meta's generic catch-all when something breaks on their backend.

3 Graph API

API Method Deprecated

You're calling an API endpoint or using a parameter that Meta has officially deprecated and removed in the Graph API version you're targeting.

102 Graph API

Session Expired

The user's login session tied to the access token has become invalid. This happens when a user logs out of Facebook, changes their password, or the session times out after an extended period.

341 Graph API

Application Limit Reached

Your Facebook App has hit a temporary hard ceiling on the volume of operations it can perform. This is a stricter version of rate limiting typically triggered by sustained high-volume usage patterns.

506 Graph API

Duplicate Post

You attempted to create an ad or post that Meta considers identical to one you recently submitted. Meta blocks exact duplicates to prevent spam and accidental double-submissions.

1885585 Account & Billing

Account in Penalty State

Your ad account has been placed in a restricted penalty state due to repeated or severe policy violations. Unlike a full disable, your account still exists but is severely limited in what it can do—budgets are capped and new campaigns may be blocked.

2446076 Account & Billing

Currency Mismatch

You're trying to set a budget or bid amount in a currency that doesn't match the ad account's configured currency. Each Meta ad account is permanently locked to one currency at creation time.

1487791 Account & Billing

Automatic Payment Failed

Meta attempted to automatically charge your payment method on file for accumulated ad spend, but the transaction was declined by your bank or payment provider.

1815006 Creative & Copy

Video Duration Exceeds Limit

The video you uploaded exceeds the maximum duration allowed for the selected ad placement. Different placements have different limits—Stories allow 15 seconds, Reels up to 90 seconds, and Feed placements up to 240 minutes.

1487958 Creative & Copy

Call to Action Required

Your ad configuration is missing a Call to Action (CTA) button, which is mandatory for the campaign objective or ad format you selected. Conversion, traffic, and app install campaigns always require a CTA.

1815268 Creative & Copy

Ad Copy Contains Restricted Content

Meta's automated review system detected language in your ad copy that violates content restrictions. This includes claims about personal attributes ('Are you overweight?'), profanity, misleading health claims, or references to restricted product categories.

1443140 Creative & Copy

Malformed Destination URL

The landing page URL you provided in your ad setup is incorrectly formatted. It may be missing the protocol (http/https), contain illegal characters, have extra spaces, or use a URL shortener that Meta doesn't allow.

1885215 Creative & Copy

Creative Aspect Ratio Invalid

The image or video you uploaded has an aspect ratio that falls outside the acceptable range for the selected placement. Each Meta placement enforces specific aspect ratio requirements.

1487079 Creative & Copy

Carousel Minimum Cards Not Met

Your carousel ad doesn't have enough cards. Meta requires a minimum of 2 carousel cards to create a valid carousel ad, and you've only provided one (or none).

1885110 Creative & Copy

Branded Content Tag Required

You're running an ad that promotes a third-party brand or product (an 'influencer' or 'partnership' post), but you haven't applied the required Branded Content tag. Meta mandates transparency for paid partnerships.

1487301 Creative & Copy

Dynamic Creative Asset Limit Exceeded

You've provided more creative assets (images, videos, headlines, or descriptions) than the maximum allowed for Dynamic Creative optimization. Meta limits each asset type to prevent combinatorial explosion.

2446253 Targeting & Audiences

Excluded Audience Overlap Too Broad

Your audience exclusions are so broad that they effectively eliminate your entire target audience. The intersection of your included audience minus excluded audiences results in a deliverable pool that's too small or zero.

1885145 Targeting & Audiences

Age Restriction for Special Ad Category

You attempted to set a specific age range for a campaign flagged under a Special Ad Category (Housing, Employment, Credit). Meta enforces mandatory broad age targeting (18-65+) for these categories to prevent discrimination.

2650024 Targeting & Audiences

Custom Audience Terms Not Accepted

Before you can create or use Custom Audiences, your ad account must accept Meta's Custom Audience Terms of Service. This agreement covers data handling, privacy requirements, and permitted use of customer data.

1487299 Targeting & Audiences

Connection Targeting Deprecated

You attempted to use the legacy 'Connections' targeting feature (target people who like your Page, friends of people who like your Page, etc.) which Meta has deprecated and removed from the API.

1885160 Campaign Structure

Cannot Change Objective Post-Launch

You tried to change the campaign objective after the campaign has already been created. Meta permanently locks the objective at campaign creation time—this is by design, not a bug.

1487852 Campaign Structure

Ad Set Schedule Invalid

The start date, end date, or dayparting schedule you configured for the ad set is invalid. Common causes include setting an end date in the past, setting a start date after the end date, or specifying dayparting hours that are impossible in the selected timezone.

1885099 Campaign Structure

Too Many Ad Sets in Campaign

You've exceeded the maximum number of ad sets allowed within a single campaign. Meta caps this to maintain system performance and prevent advertisers from creating unmanageably fragmented campaign structures.

1885190 Campaign Structure

CBO Minimum Budget Per Ad Set Not Met

When using Campaign Budget Optimization (CBO), each ad set within the campaign has a minimum spend floor. Your campaign's total budget divided across all ad sets doesn't meet the per-ad-set minimum requirement.

1487530 Campaign Structure

Conversion Window Mismatch

The attribution/conversion window you selected doesn't align with the optimization event or campaign objective. For example, selecting a 1-day click window for an event that typically takes 7+ days to convert.

3146006 Pixel & Tracking

Conversion API Event Mismatch

The events sent through the Conversions API (server-side) don't match or properly deduplicate with the events sent by your Facebook Pixel (browser-side). Meta is seeing double-counted or mismatched conversion data.

1885289 Pixel & Tracking

Aggregated Event Measurement Limit

Under Apple's ATT framework and Meta's Aggregated Event Measurement (AEM) protocol, each domain is limited to 8 prioritized conversion events. You're trying to optimize for an event that exceeds this 8-event cap or hasn't been configured in your event priority list.

3146010 Pixel & Tracking

Domain Not Verified

The website domain associated with your ad's landing page or Pixel events hasn't been verified in Meta Business Manager. Domain verification is required for Aggregated Event Measurement, link editing, and to prevent unauthorized use of your domain.

1885292 Pixel & Tracking

Event Prioritization Required

You're trying to optimize for a conversion event on a domain that has Aggregated Event Measurement enabled, but you haven't assigned a priority ranking to this specific event. Without prioritization, Meta can't properly attribute iOS 14.5+ conversions.

3146015 Pixel & Tracking

Duplicate Server Events Detected

Meta is receiving identical Conversions API events multiple times without proper deduplication parameters. This inflates your reported conversions and skews optimization, causing Meta to over-optimize and potentially overspend.

2446301 Delivery & Performance

Learning Limited

Your ad set exited the learning phase without gathering enough optimization events (typically 50 conversions in 7 days). Meta's algorithm couldn't collect sufficient data to reliably optimize delivery, so performance will be inconsistent and generally worse.

1885350 Delivery & Performance

Significant Edit Reset Learning

You made a 'significant edit' to an ad set that was in or had completed the learning phase. Meta considers changes to budget (>20%), audience, optimization event, creative, or bid strategy as significant edits that reset the learning phase counter.

1487605 Delivery & Performance

Ad Delivery Inactive

Your ad is set to 'Active' but isn't actually delivering impressions. This can be caused by a combination of factors: budget exhaustion, scheduling conflicts, audience overlap with other ad sets, lost auction bids, or the ad being stuck in review.

2446310 Delivery & Performance

Audience Saturation Detected

Your ad frequency has climbed too high—the same people are seeing your ad repeatedly. Meta flags this when your frequency exceeds a threshold (typically 3-4+ for cold audiences), causing ad fatigue, declining click-through rates, and increasing costs.

1885370 Delivery & Performance

Frequency Cap Conflict

Your frequency cap settings conflict with other campaign parameters. For example, you set a frequency cap of 1 impression per week but your budget and audience size would require much higher frequency to spend the budget, or you're using a campaign objective that doesn't support frequency capping.

278 Permissions & Access

Business Admin Access Required

The action you're attempting requires Business Manager Admin-level access, but your user role is set to Employee, Analyst, or Advertiser. Only Admins can perform certain sensitive operations like managing payment methods, adding users, or changing account settings.

2654001 Permissions & Access

Two-Factor Authentication Required

Meta requires two-factor authentication (2FA) to be enabled on your Facebook account before you can access certain Business Manager features or manage ad accounts. This is a security requirement that cannot be bypassed.

1885430 Permissions & Access

Cross-Business Manager Asset Permission Denied

You're trying to use an asset (audience, Pixel, Page, or catalog) that belongs to a different Business Manager than the one your ad account is in. Assets don't automatically share across Business Managers.

294 Permissions & Access

Business Verification Required

Meta now requires your business to be formally verified before you can access certain advertising features, run ads in regulated categories, or use the Marketing API at scale. Your Business Manager hasn't completed the verification process.

1885500 Catalog & Commerce

Product Catalog Feed Error

Your product catalog data feed failed to sync. Common causes include malformed CSV/XML/JSON, missing required fields (like `id`, `title`, `availability`, `price`, `link`, `image_link`), or the feed URL returning an error.

1885510 Catalog & Commerce

Product Set Empty

The product set you're using for your Dynamic Ads (Advantage+ Catalog Ads) contains zero products. This happens when filter rules exclude everything, products fail validation, or the catalog feed hasn't synced yet.

1885520 Catalog & Commerce

Missing Product Price

One or more products in your catalog are missing the `price` field, or the price is formatted incorrectly. Meta requires a valid numeric price with a currency code for every product in a catalog used for ads.

1487050 System Specific

Unknown Ad Format

The format ID or creative payload schema generated by your dynamic scripts is completely unrecognized by Meta's validation layer.

1443132 System Specific

Missing Facebook Page

Every ad on Meta requires a Facebook Page to act as its 'identity' or 'host' in the newsfeed. You haven't assigned one in the Ad level parameters.

2446162 System Specific

App ID Missing

You launched an 'App Install' campaign but forgot to permanently link your specific registered mobile application ID.

3146002 System Specific

Pixel Not Active

You're optimizing for a conversion event, but the Facebook Pixel assigned to the ad set hasn't fired or successfully received any data historically from that specific event within the localized testing window.

100_SUB_33 System Specific

Unsupported Country

You targeted a region or geographical territory that Meta actively prohibits business operations in, normally due to strict US trade embargoes.

1357045 System Specific

Instagram Account Unlinked

You selected placement settings demanding your ad runs specifically on Instagram, but the Instagram profile connected to your Business Manager is abruptly unlinked or you failed to assign one.
