Typing stubs for certifi
Decision gist · record as of 2026-08-14
No, unless you are locked into certifi versions older than 2022.5.18.1. For any modern certifi installation, the package is redundant—certifi now includes its own type annotations. The package itself is outdated (last release 2022-06-09) and the description explicitly recommends uninstalling it if you use a newer certifi version.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Only useful if you are using certifi versions older than 2022.5.18.1; newer versions of certifi include their own type stubs, making this package unnecessary.
- Low install friction with no runtime dependencies.
- However, the package is outdated: certifi has included native type annotations since version 2022.5.18.1, making types-certifi redundant for modern certifi installations.

Alternatives
Verify before relying
pip install types-certifi
# Then use certifi with type checking:
import certifi
path: str = certifi.where()- Whether the package is actively maintained or if typeshed stubs for certifi are still being updated given certifi's native type support since 2022.5.18.1.
What it is and what it does
types-certifi is a PEP 561 type stub package that provides type information for the certifi library, allowing static type checkers like mypy, PyCharm, and pytype to understand and validate code that uses certifi. It bridges the gap between certifi and type-checking tools by supplying type hints for certifi's public API.
However, this package is now largely obsolete. The certifi package itself has included native type annotations since version 2022.5.18.1, eliminating the need for a separate stub package. If you are using a modern version of certifi, you should uninstall types-certifi to avoid redundancy and potential conflicts.
Use it for
- Type-checking legacy projects that depend on older certifi versions (pre-2022.5.18.1) without native type support.
- Enabling mypy or similar type checkers to validate certifi usage in codebases that require strict type safety.
- Development environments where type stubs are needed for IDE autocompletion and type hints in older certifi integrations.
