# NotProxy (/docs/errors/chain/NotProxy)

The sender is not registered as a proxy for the account it tried to act for. Check the `Proxies` entry of the `real` account and confirm the sender appears there with a proxy type and delay compatible with the call.

Declared by the `Proxy` pallet; it classifies to the semantic code [`not_authorized`](/docs/errors/not-authorized).
