Identify an OfferUp Seller After a Scam

Here is the trap almost every OfferUp scam victim hits. You go to file a police report, and the intake officer asks who did it. You go to fill out a small-claims complaint, and the very first field is the defendant’s legal name, followed by an address where they can be served. What you have is “sk8rboi_deals,” a phone number that no longer rings, and a photo of an item you never received. None of that is a person a court can order to appear or a detective can knock on. That mismatch, between the thin digital handle a marketplace leaves you and the flesh-and-blood identity the legal system requires, is where most cases quietly die.

OfferUp itself will not close that gap for you directly. The platform’s job is to run the marketplace, not to disclose one user’s identity to another, and its support team will point you to reporting the user, reporting the crime, and preserving your screenshots. Account information tied to the profile does exist, but it lives inside OfferUp’s systems and is released only through legal process, meaning a subpoena issued in a lawsuit or a request from law enforcement. That is a real path, but it has a chicken-and-egg problem: in many small-claims courts you need a named defendant to open the case that would let you subpoena the name in the first place. Lawful skip tracing is how you break that loop from the outside, using identifiers you already hold rather than data locked inside the platform.

Start from the strongest identifier, not the username. A bare marketplace handle is often a dead end, because it was created just for this, tied to no verified name, and reused by no one. The leverage sits in whatever the seller used off the platform to close the deal. A phone number can be researched against public records and open sources to find a subscriber or an associated name; an email can be checked for the accounts and profiles it anchors, the same lawful research behind our guide to finding someone by an email address. When all you have is the digits, the methods in our walkthrough on finding a person from a phone number alone are the honest starting point, limits and all.

Bridge identifiers together. Real identification usually is not one lookup; it is connecting a chain. A payment handle links to an email; an email links to a username reused on a social profile; that profile carries a first name and a city; a phone-number search or a current-address trace then confirms the match against public records. Where the scam ran across profiles and platforms, the techniques in our social-media investigation guide help tie the accounts back to one operator. None of this touches OfferUp’s private account data. It works entirely from what you already hold plus lawful public records and open sources.

Confirm before you name anyone. This is the step that separates a usable result from a reckless one. A single matching identifier is a lead, not proof, and naming the wrong person on a police report or a complaint is its own serious problem. Our investigators corroborate across independent sources before we report a name to you, and we tell you plainly when the trail runs cold. The output is not an accusation; it is a documented, lawful public-records finding you and your attorney or the police can act on.

Whatever role you are in, the bottleneck is the same: a real name and a real address. Send us what you actually have, even if it feels like nothing, a phone number, a payment handle, a username, a first name, a meetup spot, a vehicle you noticed. Our people-locating work draws on the same lawful sources behind our broader people-search service and full-spectrum skip tracing, and where a case may lead to a judgment, the related work in background research, asset search, and even bank-account location can matter later. We work only for lawful, permissible purposes, we never promise a recovery we cannot control, and for a legitimate matter an initial locate typically comes back within 24 hours.
