How to fix “verification failed” when buying crypto on exchanges?

Document Submission Errors

1. Blurry or low-resolution ID images prevent optical character recognition systems from extracting accurate data.

2. Photos taken in poor lighting conditions often result in glare, shadows, or overexposure that obscure key text fields.

3. Cropping too tightly around the document edges may cut off critical security features like holograms or microprinting.

4. Uploading expired passports or driver’s licenses triggers automatic rejection regardless of other details.

5. Submitting screenshots instead of original camera captures violates most exchange integrity policies.

Name and Address Mismatches

1. Using a nickname or abbreviated first name on the platform while the government-issued ID displays the full legal name.

2. Entering a P.O. Box address when the ID shows a physical residential street address.

3. Typing “St.” instead of “Street” or “Ave.” instead of “Avenue” creates inconsistency with official records.

4. Failing to include middle names or initials that appear on the ID but are omitted during registration.

5. Listing a recently changed surname without providing marriage certificates or court documents as supporting evidence.

Selfie Verification Failures

1. Wearing sunglasses, hats, or face coverings blocks facial landmark detection algorithms.

2. Holding the ID at an angle causes perspective distortion that prevents alignment verification.

3. Using outdated selfies where hairstyle, facial hair, or eyewear differs significantly from current appearance.

4. Positioning the ID outside the designated frame overlay leads to automatic cropping and data loss.

5. Attempting verification in environments with inconsistent ambient light—such as near windows or under fluorescent fixtures—creates uneven skin tone mapping.

Platform-Specific Compliance Requirements

1. Some exchanges require notarized copies for non-resident applicants, especially those from sanctioned jurisdictions.

2. Certain platforms mandate utility bills dated within the last 30 days, rejecting older statements even if otherwise valid.

3. Mobile number verification must originate from the same country code registered in the KYC profile; mismatched SIMs trigger failure.

4. Biometric liveness checks may fail if users blink excessively or move their head too quickly during motion prompts.

5. Exchanges operating under EU MiCA regulations reject IDs lacking machine-readable zones or QR-encoded authenticity layers.

Technical and Environmental Factors

1. Browser extensions like ad blockers or privacy scripts interfere with webcam access during real-time verification sessions.

2. Outdated mobile OS versions lack support for modern TLS handshake protocols required by KYC service providers.

3. Public Wi-Fi networks with captive portals disrupt secure WebSocket connections needed for live video submission.

4. Antivirus software flagging KYC iframe content as suspicious halts embedded verification widgets mid-process.

5. Device orientation sensors misreport portrait/landscape mode, causing layout shifts that break form field alignment.

Frequently Asked Questions

Q1: Can I resubmit documents immediately after a failed verification?Most platforms enforce cooldown periods ranging from 2 to 24 hours before allowing new submissions to prevent automated abuse patterns.

Q2: Why does my passport get rejected even though it’s valid for another five years?Exchanges often require at least six months of remaining validity and may reject documents issued by certain national authorities based on bilateral regulatory agreements.

Q3: Do I need to re-verify if I change my phone number or email address?Yes—any modification to contact information triggers mandatory revalidation of identity credentials to maintain audit trail integrity.

Q4: Is there a way to bypass KYC for small crypto purchases?No major regulated exchange permits full KYC exemption; however, some support tiered verification where limited transactions under $200 require only basic email and phone confirmation.
