🧭 Scenario
You already own an Adyen terminal (e.g., P400) that is currently boarded under another company account — typically a previous processor that also uses Adyen. You're moving your processing to a new provider and want to keep using your existing device instead of ordering a new one.
✅ Good news: this is supported. Adyen allows terminals to be reassigned from one company account to another, as long as the proper approvals are provided.
✅ What You'll Need to Provide
To process the company account change, the following information will be required:
Terminal details — the terminal's make, model, and serial number
Written authorization from an admin of your current (losing) company account — a clear "go ahead" email or letter from your previous processor confirming they approve the reassignment of the terminal to your new provider
💡 Tip: The written authorization must come from someone with admin-level access at the other company — not a general support agent. A short, clear email confirming their approval is typically sufficient.
📝 How to Submit the Request
Locate the terminal's make, model, and serial number. The serial number is usually printed on the back of the device or can be found in the device settings.
Contact your previous processor and request a written authorization (email is sufficient) from one of their admins confirming they approve the terminal being moved to your new company account.
Once you have both items, submit a request to your support team with the following:
Subject: Adyen Terminal Company Account Change Request
The terminal make, model, and serial number
The written authorization from the losing company's admin (attached or pasted into the email/ticket)
The name of your business and the store where the terminal will be used
Your support team will handle the rest and coordinate with the necessary parties to complete the reassignment on your behalf. They will keep you updated throughout the process.

🔧 After Reassignment — Important On-Device Step
Once the terminal has been reassigned, the old configuration must be wiped from the device before it can be boarded under your new company account.
On the terminal:
Admin Menu → Config → Remove/Erase
Your support team can walk you through this step and help with boarding the terminal to your new account if needed.
