# Errors overview

Clerk uses a set of error codes to communicate the status of an operation.

An error's type isn't always enough to understand what went wrong. In these cases, Clerk provides a more detailed error message called a long message that can help you better understand the issue.

To find the error that you're looking for, select the appropriate category in the sidenav. There are two categories of errors:

- [Backend API errors](https://clerk.com/docs/guides/development/errors/backend-api.md)
- [Frontend API errors](https://clerk.com/docs/guides/development/errors/frontend-api.md)
