This enables filtering events from thousands of buckets using a single EventBridge rule based on tags, rather than listing each bucket individually. The feature is available at no additional cost in all AWS Regions and requires no configuration changes. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does Amazon S3 Event Notifications include system-generated tags now? Yes, S3 Event Notifications now include system-generated tags in events delivered to EventBridge, SQS, SNS, and Lambda. These tags are metadata labels attached to buckets by AWS services like CloudFormation. They let you filter events across thousands of buckets using a single EventBridge rule rather than listing every bucket name individually, at no additional cost and with no configuration changes required. _Teams building event-driven pipelines on S3 track AWS feature rollouts like this via daily.dev._ ### Do I need to change my existing S3 Event Notification configuration to get system-generated tags? No, no changes are required. If AWS services such as CloudFormation have already applied system-generated tags to your buckets, S3 automatically includes them in new event notifications once you enable event notifications, at no additional cost across all AWS Regions. _Anyone maintaining S3-based automation can follow AWS changes like this through daily.dev._ ## Similar posts on daily.dev - [AWS Network Firewall now supports firewall state change notifications through Amazon EventBridge](https://daily.dev/posts/aws-network-firewall-now-supports-firewall-state-change-notifications-through-amazon-eventbridge-lz0hqnspn) · AWS · 0 upvotes · 0 comments - [Announcing agreement EventBridge notifications for AWS Marketplace](https://daily.dev/posts/announcing-agreement-eventbridge-notifications-for-aws-marketplace-g28xuhhbx) · AWS · 0 upvotes · 0 comments - [AWS Introduces Amazon S3 Annotations](https://daily.dev/posts/aws-introduces-amazon-s3-annotations-kjdrgvzd9) · InfoQ · 3 upvotes · 0 comments - [Amazon MWAA Serverless now supports Amazon EventBridge notifications/](https://daily.dev/posts/amazon-mwaa-serverless-now-supports-amazon-eventbridge-notifications--yxz4jdfyj) · AWS · 0 upvotes · 0 comments - [Unordered mode for S3 ClickPipes is now available](https://daily.dev/posts/unordered-mode-for-s3-clickpipes-is-now-available-awfb1gmox) · ClickHouse · 2 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws), [#aws-s3](https://daily.dev/tags/aws-s3) [View this post on daily.dev](https://daily.dev/posts/amazon-s3-event-notifications-now-include-system-generated-tags-nwactmvus) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Amazon S3 Event Notifications now include system-generated tags","url":"https://daily.dev/posts/amazon-s3-event-notifications-now-include-system-generated-tags-nwactmvus","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/amazon-s3-event-notifications-now-include-system-generated-tags-nwactmvus"},"datePublished":"2026-07-16T19:07:24.032Z","dateModified":"2026-09-14T09:04:25.048Z","description":"Amazon S3 Event Notifications now automatically include system-generated tags — metadata labels attached to buckets by AWS services — in events delivered to...","image":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","thumbnailUrl":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","isAccessibleForFree":true,"articleSection":"AWS","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"AWS","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/aws","url":"https://daily.dev/sources/aws"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/amazon-s3-event-notifications-now-include-system-generated-tags-nwactmvus","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":2},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"aws,aws-s3","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"AWS","item":"https://daily.dev/sources/aws"},{"@type":"ListItem","position":3,"name":"Amazon S3 Event Notifications now include system-generated tags"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/amazon-s3-event-notifications-now-include-system-generated-tags-nwactmvus#faq","mainEntity":[{"@type":"Question","name":"Does Amazon S3 Event Notifications include system-generated tags now?","acceptedAnswer":{"@type":"Answer","text":"Yes, S3 Event Notifications now include system-generated tags in events delivered to EventBridge, SQS, SNS, and Lambda.
