When you sign up and request a withdrawal at an online casino, you will almost certainly be asked to verify your identity. This process is called Know Your Customer (KYC), and it protects both the operator and the player. At Mystake-casinos, the document upload step is straightforward once you know the exact format and size rules. Ignoring these specifications can lead to rejected documents and delayed payments. Below is a practical walkthrough covering everything you need to know.
Which Documents Are Required for Verification
To comply with legal regulations, mystake-casinos requires three main types of documents. First, a government-issued photo ID – passport, driver’s license, or national identity card. Second, proof of address – a recent utility bill, bank statement, or official government letter dated within the last three months. Third, proof of payment method – for example, a screenshot of your e‑wallet account showing your name and email, or a photo of the credit/debit card you deposited with (with middle digits and CVV masked). Having these ready before you start will speed up the entire process.

Accepted File Formats for Uploading Documents
The platform Mystake-casinos casino accepts only a few common image and PDF formats. You can upload JPEG, PNG, PDF, and TIFF files. Do not upload HEIC, BMP, or WEBP files, as the system may not process them correctly. Each file must be a clear, unaltered scan or photo. Screenshots of digital documents (e.g., a PDF viewer screenshot) are acceptable as long as all details are legible. If you submit a blurry or cropped image, the verification team will reject it, and you will have to start over.
Maximum File Size and Resolution Guidelines
Every upload has a strict size limit: each individual file must not exceed 5 MB. If your scan is larger, you need to compress it before uploading. Free online tools like TinyPNG or Adobe Acrobat’s compressor work well. Additionally, the minimum resolution should be 200 DPI (dots per inch) so that text and numbers are readable. A common mistake is taking a photo of a document with a phone camera that is too dark or low‑resolution; increase the lighting and use the highest quality setting on your camera. Mystake-casinos bonus offers are often tied to smooth verification – if your documents are rejected, your bonus may be delayed.
The table below summarises the accepted formats, maximum sizes, and typical use cases for each document type:
| Document Type | Accepted Formats | Max File Size | Example |
|---|---|---|---|
| Photo ID (passport, licence, ID card) | JPEG, PNG, PDF, TIFF | 5 MB | Passport information page |
| Proof of address | JPEG, PNG, PDF, TIFF | 5 MB | Recent utility bill (electricity, water) |
| Proof of payment method | JPEG, PNG, PDF, TIFF | 5 MB | Screenshot of e‑wallet account page |
Step‑by‑Step Upload Procedure
To upload your documents, log into your account and navigate to the “Verification” or “My Account” section. Follow these steps:
- Click on “Upload Document” and select the type of document you are submitting (ID, address, payment).
- Choose the file from your computer or mobile device. Make sure the file name does not contain special characters like & or %.
- Wait for the upload to finish – a progress bar will appear. Do not refresh the page.
- After uploading all required files, click “Submit for Review”.
- You will see a confirmation message. The support team typically reviews documents within 24–48 hours.
If you have a Mystake-casinos no deposit offer pending, completing verification early ensures you can access your winnings without holdups.
Common Upload Problems and How to Fix Them
Many users run into the same issues. The most frequent is “file too large” – compress the file below 5 MB. Another is “unsupported format” – convert your file to one of the four accepted types. Sometimes the document is rejected because the proof of address is older than three months; always check the date before uploading. Also ensure that all four corners of the document are visible in the photo; cropping out edges can cause rejection. A less common but annoying issue is a mismatch between the name on your account and the name on the document. If you recently changed your surname, contact support before uploading.
Using a Mystake-casinos promo code when you sign up may unlock extra perks, but those perks only become active after your account is fully verified. Therefore, it is wise to complete the document upload process soon after registration.
Verification Timelines and What to Expect
Once you have submitted your documents correctly, the verification team at Mystake-casinos free spins promotions department will process them. Standard review time is 24 to 48 hours, but during peak periods it can take up to 72 hours. You will receive an email notification once the status changes to “Verified”. If any document is rejected, the email will explain the reason and ask you to upload a corrected version. You do not need to re‑upload the entire set – only the rejected item. Keep an eye on the spam folder.
After verification, you can withdraw funds and claim bonuses without further KYC delays. For a full overview of all available games and promotions, visit the official site: Mystake casino.
