Submitted KYC multiple times with only vague failure messages and no idea what went wrong — many people have been there. Here's a systematic walkthrough of the most common failure causes.
Cause 1: Poor Photo Quality
This is the number one reason for KYC failure. The system needs OCR to read text on your document — poor photos mean failed recognition.
Fix:
- Place document flat on a solid-colored surface (white paper, light desk)
- Ensure all four corners are in frame
- Even, sufficient lighting — no shadows, glare, or overexposure
- Don't use flash (causes reflection)
- Sharp focus with legible text
- No cropping or editing
If you haven't started yet, register on Binance first and prepare your documents before submitting.
Cause 2: Information Mismatch
The name, date of birth, or other info you entered during registration doesn't match your document.
Common issues:
- Incorrect name spelling/romanization
- Date format error (month and day swapped)
- First/last name order wrong
Fix: Check your profile settings to ensure every field matches your document exactly. Contact support if corrections are needed.
Cause 3: Expired Document
Using an expired document guarantees rejection.
Fix: Use a document within its validity period. If your ID is expired, try a passport instead.
Cause 4: Facial Recognition Failure
Document uploaded successfully but the face scan step fails.
Common causes and fixes:
- Poor lighting: Find a well-lit indoor area, avoid backlighting
- Wearing glasses: Remove them and retry
- Heavy makeup or obstructions: Keep face natural, nothing blocking
- Camera permission issues: Confirm the app has camera access
- Poor front camera: Try a phone with a better front camera
- Incomplete gestures: Follow prompts for turning head, blinking, etc. — don't rush
Cause 5: Unsupported Document Type
Not all document types are accepted. Temporary IDs, household registration books, and military IDs may not be supported.
Fix: Use a standard national ID, passport, or driver's license.
Cause 6: Document Already Used by Another Account
One document can only be tied to one Binance account. If you previously registered with the same document (perhaps forgotten), KYC on a new account will fail.
Fix:
- Try to recall if you registered another account and attempt recovery
- If the old account is truly unnecessary, contact support to deactivate it
- Support may require proof materials
Cause 7: Age Restriction
Binance requires users to be at least 18 years old. If your document shows you're under 18, KYC won't pass.
Cause 8: Temporary System Issues
Occasionally Binance's KYC system experiences glitches, causing even valid submissions to fail.
Fix: Wait a few hours or try the next day. If the issue persists, contact support to confirm system status.
Last Resort: Manual Review
If automated review keeps failing, request manual review:
- Contact Binance live support
- Explain that you've attempted automated KYC multiple times without success
- Support may request additional materials:
- Selfie holding your ID
- A note with the date and "Binance" written on it
- Other supplementary ID documents
Manual review takes longer (1-7 days) but has a higher pass rate since a real person handles your materials.
Tips for First-Try Success
- Operate in good indoor lighting during daytime
- Use your phone (better than a computer webcam)
- Hold the document steady — check clarity before submitting
- Double-check all entered information against your document
- If the first attempt fails, don't immediately retry — analyze the failure reason first
KYC can be frustrating, but it's an important safeguard for your account security. Handle it patiently once, and you'll never need to deal with it again.
