Selling on OfferUp can be quite profitable—whether you’re reselling collectibles, running a side hustle, or running a full-time e-commerce business.
But many sellers often encounter a frustrating problem: account bans. Most often, bans are linked to IP addresses, especially if you manage multiple accounts or use a shared network.
Like most online platforms, OfferUp uses risk management systems to detect suspicious activity. The following situations may trigger a suspension:
IP Address Association: If your IP has been associated with a previously banned account, your new account may be immediately flagged.
Managing Multiple Accounts with the Same IP: By default, OfferUp associates one device/IP with only one seller account.
Geographic Inconsistency: If the listing location differs significantly from the city or state specified on your account, this may raise suspicion.
Shared IP or Data Center IP: Low-cost or free proxies often operate in data centers (computer rooms), making them easily identified and blocked by OfferUp.
In other words, if you don’t have a dedicated, clean IP address, even if you comply with the rules, your account could still be at risk of being suspended.
Why Dedicated Residential Proxy is a Key Weapon for OfferUp Sellers
A Dedicated Proxy assigns you a dedicated IP address that is used only by you and is not shared with others.
Paired with a Static Residential Proxy (from a real ISP and specific location), it can make your account appear more natural and credible.
Advantages of using a dedicated residential proxy:
🛡️ Prevent account suspension: Dedicated IP addresses don’t overlap with others, preventing collective penalties
🔑 Multi-account security: Each account is assigned a unique IP address, significantly reducing risk management risks
📍 Precise positioning: The proxy’s location aligns with the sales region, increasing credibility
🚀 Increased visibility: Localized IP addresses help products appear in search results for nearby buyers
📶 Stable connection: No random IP switching, avoiding “suspicious login” warnings
OfferUp Dedicated Proxy Usage Tips
Choose a residential proxy (ISP IP) instead of a data center proxy – Residential proxies are more authentic and harder to identify
One account, one IP – Each account must be associated with a dedicated proxy to prevent account linkage
Agent region aligns with sales region – If selling in New York, use a New York-based proxy IP](https://okkproxy.com/pricing/residential-proxies)
Avoid frequent IP changes — Stability is more important than cost. Frequent switching can easily trigger risk control
Fixed binding of device and proxy — Try to use the same device + the same IP to log in to the account to reduce the difference in device fingerprint
Gradually maintain the account — Do not post a large number of posts to the new account immediately. Use the proxy to simulate normal user behavior first and gradually increase the account weight

FAQ

A dedicated proxy is assigned to only one user, while a shared proxy is shared by multiple users, significantly increasing the risk of account suspension.
