1win Document Upload: Format and Size Rules
Navigating the verification process at an online casino is a crucial step for a secure and smooth experience. This guide provides a detailed, step-by-step walkthrough of the document upload procedure at 1win, explaining the rules, requirements, and how to troubleshoot common issues.
Why 1win Requires Document Verification
Document verification, often called Know Your Customer (KYC), is a standard security practice mandated by international licensing authorities. For the 1win casino, this process confirms your identity, age, and payment method ownership. This protects your account from unauthorized access and prevents fraudulent activities. Completing verification is essential before you can process large withdrawals or claim certain promotions like a lucrative 1win bonus.

Required Documents for Your 1win Account
You will typically need to provide clear photos or scans of several documents. The exact requirements may vary slightly depending on your country, but the core set is universal.
- Proof of Identity: A government-issued photo ID such as a passport, driver’s license, or national ID card.
- Proof of Address: A recent utility bill (electricity, water, gas), bank statement, or official government letter dated within the last three months.
- Proof of Payment Method: If you deposited via card, a photo of the front side (with the last 8 digits visible, other numbers can be hidden) is required.
Accepted File Formats and Size Limits
Submitting documents in the correct format is critical for a quick approval. The 1win platform has specific technical requirements to ensure files are readable by their security team.
| Document Type | Accepted Formats | Maximum File Size | Key Requirement |
|---|---|---|---|
| All Documents (ID, Address, Card) | JPG, PNG, PDF | 10 MB | File must be clear and legible. |
| Proof of Identity | JPG, PDF | 8 MB | All four corners must be visible. |
| Proof of Address | PDF, PNG | 5 MB | Your name and address must be clear. |
Step-by-Step Upload Guide
Follow these steps to successfully submit your documents through the 1win website or app.
- Log in to your account and navigate to your profile or account settings section.
- Look for a “Verification,” “KYC,” or “Account Verification” tab and click on it.
- You will see options to upload different documents. Select the correct category (e.g., Identity Proof).
- Click “Upload” and select the correct file from your computer or smartphone. Ensure the image is not blurry.
- Repeat the process for each required document. Once all are uploaded, submit the verification request.
- The 1win security team will review your submission. This typically takes 24 to 72 hours.
Troubleshooting Common Upload Problems
If your documents are rejected, it’s usually for a simple, fixable reason. Here are the most common issues:
- Blurry Images: Ensure the document is placed on a flat surface and photographed in good lighting. Avoid glares.
- Incorrect File Format/Size: Re-save your file as a JPG or PNG and compress it if it exceeds the 10 MB limit.
- Cropped Document: The entire document must be visible in the image, including all edges.
- Expired Document: Your ID must be valid, and proof of address must be recent (within 90 days).
