Quick answer
Requirements differ between operators, but the categories are consistent across the industry. Preparing the right document in the right format is what turns a multi-day cycle into a same-day approval.
Tier 1: Government photo identification
| Feature | Generally accepted | Notes |
|---|---|---|
| Passport | Yes | Most reliable — standardised internationally |
| National ID card | Yes | Both sides usually required |
| Driving licence | Yes | Photo licences only; both sides often needed |
| Residence permit | Usually | Often accepted where it carries a photo |
| Student or work ID | No | Not government issued |
| Expired document | No | Rejected automatically |
| Photocopy of a photocopy | No | Security features are not verifiable |
Requirements for the image itself:
- Currently valid, not expired
- All four corners visible with a margin
- Text readable without zooming
- No glare across the photo or security features
- Colour, not greyscale
- Both sides if the document is a card
- Original photo or scan, not a screenshot
Tier 2: Proof of address
Requested when jurisdiction needs confirming, or at higher verification tiers.
| Feature | Generally accepted | Common condition |
|---|---|---|
| Utility bill (electricity, gas, water) | Yes | Dated within ~3 months |
| Bank or credit card statement | Yes | Full statement, not a transaction screenshot |
| Council or local tax bill | Yes | Current period |
| Government correspondence | Usually | Official letterhead required |
| Internet or landline bill | Usually | Some operators exclude telecoms |
| Mobile phone bill | No | Commonly excluded |
| Handwritten or self-generated letter | No | Not independently verifiable |
| Document in another person's name | No | Must match the account holder |
Requirements for the document:
- Your full name, matching your account and ID
- Your full address
- A visible issue date within the accepted window
- The issuer's name or logo
- The complete document, including headers and footers
Tier 3: Selfie and liveness checks
- Good, even lighting on your face
- No hat, sunglasses or face covering
- Plain background
- Holding the ID clearly, if requested, with its text readable
- Live capture through the interface where required — an uploaded photo may be refused
Liveness checks exist because a static photo can be faked. If the interface asks you to turn your head or blink, that is the system working as designed.
Tier 4: Payment method and source of funds
Requested for larger amounts or specific risk indicators.
| Document | Purpose |
|---|---|
| Wallet ownership proof | Confirms you control the address funds came from |
| Exchange account screenshot | Links a deposit to an account in your name |
| Payslips or employment letter | Establishes income |
| Bank statements | Shows fund accumulation over time |
| Sale or investment records | Explains a one-off large sum |

Preparing well
Check what has actually been asked for
Requests are specific. Sending extra documents rarely helps and sending the wrong ones restarts the process.
Align your account details with your ID first
Name spelling, date of birth and country. Mismatches are the leading cause of rejection.
Photograph in daylight on a dark, plain surface
Flash creates glare on holograms. Natural light does not.
Submit everything in one go
Partial submissions queue separately and multiply the wait.
Keep copies of what you sent
So you can see exactly what was submitted if a follow-up arrives.
Summary
Government photo ID is the core requirement, with a passport being the most universally accepted. Proof of address means a utility bill or bank statement in your own name, dated within about three months. Selfies and source-of-funds documents apply at higher tiers. Match your account details to your ID, photograph everything flat in daylight, and submit the full set at once.
