Device pairing issues ("already registered")

The serial or device was partly registered before — clear the state or use a fresh key, then re-pair.

An "already registered" or pairing error means ZIMRA already has a device against that serial, or a previous pairing didn't finish cleanly.

What to check

Confirm you're not re-registering a serial that's already live on another till.
Confirm the branch details match ZIMRA.
If a pairing/activation key was consumed by a failed attempt, request a fresh key and pair again.

For the desktop agent

Re-pair with a new enrolment code from the portal (Devices → the device → Pair agent). If the problem persists, raise a ticket with the serial and device name.
