# CodePipeline Limitations

> This guide covers limitations, quotas, and naming rules for AWS CodePipeline essential for designing scalable CI/CD workflows.

In this guide, we’ll walk through the key limitations, quotas, and naming rules for AWS CodePipeline. Understanding these restrictions is critical for designing scalable, reliable CI/CD workflows.

## Unique Naming Constraints

Every pipeline, stage, and action name must be unique within its scope:

* Pipeline names must be unique per AWS account and region.
* Stage names must be unique within a pipeline.
* Action names must be unique within their stage.

You can reuse common stage names (for example, `Source` or `Deploy`) across different pipelines, but you cannot duplicate them inside the same pipeline.

## Regional Quotas and Requesting Increases

Most CodePipeline quotas are applied per AWS Region. For example, the default limit of 1,000 pipelines refers to pipelines per region.

  If you hit a regional quota, you can request an increase via the [AWS Support Center](https://console.aws.amazon.com/support/home). Approval may take up to two weeks.

## Core Service Limits

Below are the default CodePipeline quotas you should plan for in each region:

| Resource            | Default Limit | Scope                  |
| ------------------- | ------------- | ---------------------- |
| Pipelines           | 1,000         | Per account per region |
| Stages per pipeline | 2–50          | Per pipeline           |
| Actions per stage   | 1–50          | Per stage              |

> Actions within a stage can execute in parallel or sequentially. The only overall cap is the per-stage limit.

## Additional Considerations

* Manual approval actions will time out after 7 days without a decision.
* Artifacts are typically stored in Amazon S3. While S3 supports virtually unlimited objects, general S3 limits still apply.

For the full list of quotas and best practices, see the [AWS CodePipeline Limits](https://docs.aws.amazon.com/codepipeline/latest/userguide/limits.html) documentation.
