Key takeaway: Polymarket's Know Your Customer (KYC) process in the UK involves identity verification, proof of address, and sometimes source-of-funds documentation. Completion typically takes 24–48 hours. This guide walks you through each step, common delays, and what to expect after verification.
What Is KYC and Why Does Polymarket Require It?
Know Your Customer (KYC) is a regulatory requirement that financial platforms—including prediction markets—must follow to comply with anti-money laundering (AML) and counter-terrorism financing (CTF) laws. In the UK, the Financial Conduct Authority (FCA) and the National Crime Agency oversee these obligations.
Polymarket, as a global prediction market platform, implements KYC to verify the identity of its users and ensure funds aren't derived from illegal activity. For UK users, this means providing government-issued identification, proof of your current address, and occasionally evidence of where your trading capital originates.
The process protects both you and the platform. It prevents fraudulent account creation, reduces the risk of your account being compromised by bad actors, and ensures the platform operates within legal boundaries. Without completing KYC, you'll face restrictions on deposits, withdrawals, and trading activity.
Step-by-Step: How to Start Your Polymarket KYC Verification
1. Create and Secure Your Account
Before you can initiate KYC, you'll need an active Polymarket account. Sign up using a valid email address and set a strong password—at least 12 characters, mixing uppercase, lowercase, numbers, and symbols. Enable two-factor authentication (2FA) immediately, using either an authenticator app like Authy or Google Authenticator, or SMS-based 2FA. This protects your account from unauthorised access during and after the verification process.
2. Navigate to the Verification Section
Once logged in, go to your account settings or profile menu. Look for a "Verification," "KYC," or "Identity Verification" tab. On Polymarket, this is typically found under account settings in the top-right menu. Click it to begin the verification flow. You'll be presented with a clear outline of what information you need to provide and the order in which you'll provide it.
3. Provide Your Personal Information
You'll be asked to enter:
- Full legal name (as it appears on your passport or driving licence)
- Date of birth
- Nationality
- Current residential address (full postcode required)
- Email address and phone number
Ensure every detail matches your official documents exactly. Mismatches—even a middle initial or a different spelling of your surname—can cause delays or rejection. If you've recently changed your name, have documentation ready to explain the change.
Gathering and Uploading Required Documents
Identity Verification: Accepted Documents
Polymarket accepts the following as primary identity documents for UK users:
- UK Passport: Valid or expired within the last 5 years. Colour copy or scan of the photo page and the page with your signature.
- UK Driving Licence: Photocard version only. Both sides required (front and back).
- National ID Card: If you hold one from another EU or EEA country, this is acceptable. Colour scan of both sides.
- Visa or Residence Permit: If you're a non-UK national, a valid visa or biometric residence permit with your photo and signature is required.
Documents must be in colour, clearly legible, and show your full face. Photocopies or black-and-white scans are typically rejected. Ensure the document hasn't expired (or, in the case of passports, expired less than 5 years ago). If your document is damaged, faded, or partially obscured, re-scan it or submit a replacement.
Proof of Address: What Polymarket Accepts
You'll need a document dated within the last three months that shows your name and current UK address. Acceptable documents include:
- Utility bill (gas, electricity, water, or broadband)
- Bank or building society statement
- Mortgage statement or tenancy agreement
- Council tax bill or local authority letter
- Recent letter from your employer or pension provider
- Insurance policy document (home, car, or pet insurance)
The document must clearly display your full name, your residential address, and the date of issue or the period it covers. If you've recently moved, you may need to provide a tenancy agreement or a letter from your landlord in addition to a utility bill, as utility bills sometimes take 4–6 weeks to arrive after moving.
Source of Funds (When Required)
Depending on your account activity or deposit amount, Polymarket may ask for proof of the source of your trading capital. This is more common if you're depositing a large sum (typically £5,000 or more) or if the platform's automated checks flag your account for additional scrutiny.
Acceptable documents include:
- Bank statements showing regular salary deposits
- Investment account statements (ISA, pension, etc.)
- Inheritance documentation or gift letter from a family member
- Business accounts or tax returns (if self-employed)
- Property sale documents (if funds come from a property sale)
Ensure the document clearly shows the source of the funds and is dated recently enough to be relevant to your deposit.
The Upload Process and Technical Tips
File Format and Size Requirements
Polymarket typically accepts uploads in JPEG, PNG, or PDF format. File size should not exceed 10 MB per document. Most modern smartphones take photos that meet these requirements automatically.
Taking Clear Photos of Your Documents
If you're photographing documents rather than scanning them:
- Use natural daylight or a bright lamp to avoid shadows or glare.
- Place the document on a flat, contrasting surface (dark background for light documents, light background for dark documents).
- Hold your phone or camera directly above the document, parallel to it, to avoid skewing or perspective distortion.
- Ensure all four corners and all text are visible and in focus.
- Take separate photos for each side of two-sided documents (e.g., both sides of a driving licence).
- Avoid taking photos of documents held in your hand or at an angle.
Uploading Your Files
Once you've prepared your documents, the Polymarket verification interface will guide you through uploading them. Typically, you'll click a button to select files from your device, or drag and drop them into a designated area. The platform will show you a preview of each upload before you confirm. Double-check that the preview is clear and complete before proceeding.
Upload documents in the order requested by the platform. Don't skip steps or try to upload everything at once; the system is designed to process them sequentially.
What Happens After You Submit: Timeline and Status Updates
Automated Checks (Immediate to 1 Hour)
Once you've uploaded your documents, Polymarket's system performs immediate automated checks. These include verifying that files are readable, that documents haven't expired, and that the information provided matches across all documents. If an automated check fails—for example, if a photo is too blurry—you'll receive an error message and can re-upload the file immediately.
Manual Review (4–48 Hours)
After passing automated checks, your submission enters a manual review queue. A compliance officer will examine your documents, verify the information, and check for any red flags. This typically takes 24–48 hours, though during busy periods it can take longer. You can track the status of your verification in your account dashboard, which will show whether your submission is "Pending," "Under Review," or "Approved."
Common Reasons for Rejection or Delay
Document quality issues: Blurry photos, glare, or partially obscured information. Solution: Re-upload a clearer image.
Information mismatches: Your name, address, or date of birth differs between documents or doesn't match what you entered in the form. Solution: Verify the exact spelling and format on each document and re-enter your details carefully.
Expired documents: Your passport or driving licence has expired beyond the acceptable window. Solution: Renew your document and re-submit.
Address concerns: Your proof of address is older than three months or doesn't match your stated residential address. Solution: Obtain a more recent document or clarify your address if you've recently moved.
Source of funds unclear: Your bank statement or other proof doesn't clearly show where your deposit capital came from. Solution: Provide additional documentation or a written explanation.
After Approval: What You Can Do
Deposit and Withdrawal Limits
Once your KYC verification is approved, you'll have access to Polymarket's full functionality. You can deposit funds using supported payment methods (typically bank transfers and cryptocurrency), place bets on prediction markets, and withdraw your winnings. Your deposit and withdrawal limits depend on your verification tier and account history; most newly verified UK users can deposit and withdraw up to £10,000 per transaction, with higher limits available upon request.
Account Security After Verification
Your KYC information is sensitive. Keep your account secure by:
- Maintaining a strong, unique password.
- Keeping 2FA enabled at all times.
- Never sharing your login credentials or recovery codes.
- Logging out of shared devices after use.
- Monitoring your account for unauthorised activity.
If you suspect your account has been compromised, change your password immediately and contact Polymarket's support team.
Troubleshooting Common KYC Issues
My Upload Was Rejected—What Now?
Check the rejection reason provided by the platform. Most rejections are due to document quality or information mismatches. Re-read the requirements, prepare a new document or photo, and re-submit. If you're unsure why a document was rejected, contact Polymarket support with details of the rejection message.
My Verification Has Been Pending for More Than 48 Hours
During peak periods, manual review can take longer. Check your email for any requests for additional information. If you haven't received any communication and it's been more than 72 hours, contact Polymarket's support team via their in-app chat or email. Provide your account details and submission date.
I've Moved House—Do I Need to Re-Verify?
If you've moved, you'll need to update your address in your account settings. Polymarket may require you to provide a new proof of address document. This is typically a faster process than initial KYC, but it's best to do it before initiating large withdrawals.
My Identity Document Is About to Expire
If your passport or driving licence is expiring within the next few months, consider renewing it before submitting your KYC. An expiring document may be accepted initially, but you'll likely need to re-verify with a renewed document before making large transactions.
Frequently Asked Questions
How long does Polymarket KYC take in the UK?
Most verifications are completed within 24–48 hours. Automated checks take minutes; manual review takes the bulk of the time. In quiet periods, you may be approved within a few hours. During busy periods, it can take up to 72 hours.
Is my personal data safe with Polymarket?
Polymarket is required to protect your data under UK data protection laws (GDPR). Your information is encrypted and stored securely. However, like any online platform, there is always a risk of data breaches. Use a strong password and 2FA to protect your account.
Can I trade on Polymarket before my KYC is approved?
No. You cannot deposit funds or place bets until your KYC verification is complete and approved. You can create an account and explore the platform, but trading functionality is locked until verification is finished.
What if I'm not a UK citizen but live in the UK?
You can still complete KYC if you have a valid visa, residence permit, or national ID card from an EU/EEA country. Provide the appropriate document and proof of your UK address, and you'll be verified under the same process as UK citizens.
Do I need to re-verify if I change my address?
You'll need to update your address in your account and provide a new proof of address document. This is usually a faster process than initial verification, but Polymarket may require it before allowing large withdrawals.
What happens if my KYC is rejected?
You'll receive a notification explaining why. Most rejections can be resolved by re-submitting clearer documents or correcting information mismatches. If you believe your rejection was in error, contact Polymarket support for clarification.
Is prediction market trading regulated in the UK?
