Amazon Seller Central is one of the strictest web identity surfaces — IP reputation, cookie history, and browser fingerprint all feed risk models. Multilogin gives each seller entity an isolated Mimic profile with sticky ISP/residential proxy. Mobile Seller app flows can sit on cloud phone separately — same hybrid pattern as Shopee/Lazada.
Marketplace → profile defaults
| Marketplace | Timezone | Proxy type | Notes |
|---|---|---|---|
| Amazon.com (US) | America/Los_Angeles or seller state | US sticky ISP/residential | Avoid rotating DC pools |
| Amazon.co.uk | Europe/London | UK sticky | Post-Brexit entity separation |
| Amazon.de / .fr / .it | Local EU TZ | Country-matched sticky | One profile per legal entity |
| Amazon.co.jp | Asia/Tokyo | JP mobile or ISP | Strict device signals |

Profile hardening checklist
- Mimic engine, Windows or macOS preset consistent with registration history
- Sticky proxy — never rotate mid-session (proxy strategy)
- WebRTC off or proxy-aligned; DNS via proxy
- Warm profile: browse Amazon as shopper before Seller Central login
- Fingerprint audit before automation
2FA and automation boundaries
| Task | Automation |
|---|---|
| Login + 2FA | Human only on prod accounts |
| Inventory CSV upload | Playwright post-login, low frequency |
| Order reports download | Queue worker OK with lease |
| Account health appeals | Manual — no scripted submissions |
| Bank / tax / identity | Never automate |
Queue pattern: queue worker + CDP reconnect for long report pulls.
Cross-border agency ops
Separate Multilogin profiles per legal entity and marketplace — US stack: US CMDB guide; EU stack: EU CMDB guide. Link by client_id only — never share cookies between US and EU profiles if entities differ.
