How to verify my identity on Binance if my documents keep getting rejected?

Document Submission Best Practices

1. Ensure all submitted documents are unaltered, full-frame, and in color — cropped, blurred, or grayscale images trigger automatic rejection.

2. Match the name, date of birth, and nationality exactly between your ID document and the information entered during registration.

3. Submit only government-issued IDs such as passports, national ID cards, or driver’s licenses — internal memos, utility bills, or screenshots are invalid.

4. Avoid glare, shadows, or reflective surfaces when photographing documents — use natural lighting and a plain background.

5. Confirm that your document has not expired and remains valid for at least six months beyond submission.

Common Rejection Triggers

1. Inconsistent facial features between live selfie and ID photo — avoid heavy filters, sunglasses, hats, or obscured facial contours.

2. Mismatched document issuance country and declared residency — for example, submitting a Brazilian passport while declaring permanent residence in South Korea without supporting proof.

3. Tampered or digitally modified files — even minor brightness/contrast adjustments may violate Binance’s integrity verification algorithms.

4. Unclear text on ID — characters must be legible without zooming; fonts smaller than 8pt often fail OCR validation.

5. Background interference in selfie — ensure no other person, screen, or mirror appears in the frame.

Technical Requirements for Upload

1. File format must be JPEG, JPG, or PNG — PDFs are accepted only for residence certificates, never for primary IDs.

2. Maximum file size is 8 MB per document — oversized scans cause silent truncation and incomplete metadata transmission.

3. Image resolution must be between 640×480 and 4000×4000 pixels — undersized images lack forensic detail; oversized ones distort edge detection.

4. EXIF data must remain intact — disabling geotagging or stripping metadata before upload breaks signature-chain validation.

5. Browser-based uploads require WebRTC-enabled environments — legacy browsers like Internet Explorer or outdated Chrome versions may corrupt binary payloads.

Verification Workflow Timing

1. Manual review queues typically process submissions within 15 to 48 business hours — weekends and public holidays extend this window.

2. Each rejection resets the review clock — resubmitting identical documents within two hours guarantees another automated rejection.

3. Three consecutive rejections trigger a 72-hour lockout from the KYC portal — no new attempts permitted until cooldown expires.

4. Time-stamped server logs reflect UTC+0 — discrepancies between local device time and NTP-synchronized timestamps may invalidate timestamp-dependent validations.

5. Session tokens expire after 18 minutes of inactivity — abandoning the verification flow mid-process voids all uploaded assets.

Frequently Asked Questions

Q: Can I submit a notarized copy of my passport if the original is held by an embassy? A: No. Binance requires original, unnotarized, machine-readable documents. Notarization invalidates authenticity checks performed via ICAO-compliant MRZ parsing.

Q: Why does my driver’s license get rejected even though it’s valid and unexpired? A: Some jurisdictions issue laminated or holographic licenses incompatible with infrared liveness detection — switch to passport or national ID if available.

Q: Does using a virtual background during the selfie step affect approval? A: Yes. Virtual backgrounds disrupt depth-map analysis and facial topology mapping — physical neutral backgrounds only.

Q: Can I change my registered country of residence after KYC rejection? A: No. Country selection is immutable post-registration — mismatched residency claims require account termination and new registration.
