Amazon Section 3 and related accounts: when a second seller account is allowed and how to run several securely

"Section 3" refers to the termination and suspension section of the Amazon Services Business Solutions Agreement. A Section 3 deactivation notice that mentions a related account means Amazon has connected the account to another one that was suspended or that it believes shouldn't exist. This guide covers what the rule is, when more than one account is legitimate, and how to run several accounts with proper security. It doesn't cover hiding accounts from Amazon. That breaks the agreement and tends to fail exactly when the stakes are highest.

What the rule says

Amazon's Seller Code of Conduct says you may operate one Selling on Amazon account per region, unless you have a legitimate business need for more and all of your accounts are in good standing. Amazon's help pages have historically given examples of legitimate need:

• You own several brands and run a separate business for each.
• You manufacture products for two distinct and separate companies.
• You've been recruited into an Amazon program that requires a separate account.

Wanting a "backup" account in case the first one is suspended isn't a legitimate need. Opening a new account after a suspension is a direct violation and usually ends with every connected account being closed.

How Amazon connects accounts

Amazon doesn't publish its method, but sellers and consultants consistently report that accounts get connected through overlapping business identity: legal entity, tax ID, bank account, credit card, addresses, phone numbers and email. They're also connected through technical signals such as devices and network locations. Shared people matter too: the same user logging into both.

The practical point for a legitimate operator: you don't need to hide that two accounts belong to the same group. You need each one to be a clean, separately run business, so a problem in one is judged on its own facts.

Running more than one account properly

1. Keep each business genuinely separate

• A separate legal entity, tax ID and bank account for each business, as required, plus separate bookkeeping.
• Distinct brands and catalogs. Two accounts selling the same products to the same customers is the clearest sign that a second account has no business reason.
• Brand Registry for each brand, with the trademark owner listed correctly.

2. Give people access, not passwords

Seller Central has User Permissions. Invite each employee, VA or agency user with their own login and only the permissions their job needs, such as inventory, advertising or reports. That keeps an audit trail, lets you revoke access in seconds, and avoids the risky habit of sharing the main account's password and 2FA codes.

3. Secure the devices and sessions

• Use an authenticator app or a hardware key for two-step verification, registered to the account owner or the business, never a personal phone number of a VA who might leave.
• Keep work sessions for each business in a separate browser profile (a regular Chrome profile, or a team browser like AdsPower or Multilogin if many people need controlled access). That prevents cookie mix-ups, someone accidentally listing in the wrong account, and one compromised session exposing another business.
• Have staff log in from a consistent, known location, either the office network or a dedicated static IP for the team, so unusual logins stand out. Avoid public VPN exit nodes. They're shared with strangers and trip security checks.

4. Keep every account in good standing

The "good standing" condition is the one people forget. A related-account rule cuts both ways: an unresolved policy problem in one account puts the others at risk. Check Account Health in each account weekly, and resolve listing, IP and performance notifications quickly.

If you received a related-account deactivation

1. Don't open another account. It makes the situation worse and is itself grounds for permanent closure.
2. Find the connection. Amazon's notice sometimes names the related account. If not, think through shared people, payment methods, addresses and devices.
3. If the related account is legitimately yours, fix that account's problem first. Its reinstatement is often the path back for both.
4. If the connection is wrong, for example a former employee, a shared office or a previous owner of a device, write a factual appeal with evidence: contracts, invoices, entity documents.
5. Follow the emergency account lockout plan for funds, inventory and customer service while you wait. For large inventory or funds on hold, an experienced Amazon seller attorney is often worth the fee.
