Can't Verify Your Identity on Polymarket US?
If Polymarket US can't verify your identity automatically, it may ask you to upload a government-issued ID and complete a selfie check, and if manual review is needed, processing can take longer. You can't deposit or trade until the check (KYC) is complete, and the result shows in the app.

The four results a check can end in
Polymarket US's partner documentation, written for apps that onboard users, says it uses Socure as its identity verification provider and lists four outcomes:
| Outcome | What it means |
|---|---|
| Instant approval | The identity was verified immediately |
| Document verification | The provider needs a photo ID |
| Manual compliance review | Automated checks were inconclusive; the participant waits |
| Rejection | Verification or risk assessment failed; the participant cannot trade |
Getting unstuck

- What you were trying to do
- Error messages
