# `CHECK_NOT_FOUND` No such lookup in your account

Source: https://checkslip.com/en/problems/check-not-found

- **HTTP status**: `404`
- **Credit**: No credit taken

## Meaning

No lookup with this request_id in this account, or it is older than the 90 days we keep. This code is named CHECK_NOT_FOUND for compatibility; the "check" in the name means the same lookup.

## Fix

Check the request_id and which account the key belongs to.
