Why Was My ID Scan Rejected for KYC?

By Scanner.cam Editorial Team · Updated 6 Nov 2026 · 5 min read

Quick answer

Most ID scans are rejected for KYC for fixable reasons: glare on the card, cropped edges, a photo that is too dark, or details that do not match the account. Re-scan with better light, check every edge is in frame, and confirm the name and expiry match before you upload again.

Why Was My ID Scan Rejected for KYC? — Scanner.cam guide

A KYC rejection is frustrating — you did the scan, uploaded it, waited, and got a "document not accepted" message with no useful explanation. The good news is that most rejections come from a short list of problems, and almost all of them are in the scan itself rather than in your identity. Work through the reasons below in order, fix the one that matches your scan, and re-upload.

The 7 most common rejection reasons

Glare on the card. Flash or overhead light reflects off the laminate and whites out the photo or the ID number. Fix: turn the flash off, use side light, and tilt the card until the reflection moves away.
Cropped edges or corners. Automated checks look for the full card outline. If a corner is cut off or a finger covers the edge, the system flags the document as possibly altered. Fix: re-scan with a small margin around the whole card.
Blurry or low-resolution text. Small print on an ID card needs a close, steady shot. Fix: hold the camera closer, rest your arms on the table, and check the text at full zoom before uploading.
Only one side uploaded. Most KYC checks need the front and the back. Fix: upload both sides in a single PDF, front first.
Expired document. An expired ID fails verification no matter how good the scan is. Fix: check the expiry date on the card before you scan — renew it first if it has passed.
Name mismatch. The name on the ID must match the name on the account exactly, including spelling and middle names. Fix: check the account name against the card, and correct whichever one is wrong before re-uploading.
Wrong document type. Some services accept passports but not driving licenses, or national IDs but not student cards. Fix: read the portal's accepted-documents list and upload one of the types it names.

Fix it and re-upload

Look at your rejected scan first. Open the file you uploaded and check it the way a verification system would: is every edge in frame, is the text sharp, is the photo free of glare?
Re-scan in better conditions. Dark matte background, side light, no flash, camera close and steady. Scan both sides.
Check the file itself. Confirm the format is one the portal accepts — usually PDF or JPG — and the size is under its limit, commonly 2–5 MB.
Match the details. Confirm the name, date of birth, and expiry date on the card match the account exactly.
Re-upload and wait. Most automated checks return a result within minutes. If it is rejected a second time for the same reason, contact support and ask which specific check failed — they can usually tell you.

When the problem is not the scan

Sometimes the scan is fine and the rejection has another cause. An ID that is damaged, heavily worn, or taped together may be unreadable no matter how well you photograph it — in that case, request a replacement card. A name that changed after marriage, or a transliteration difference between your account and your ID, will keep failing until the account details are corrected. And some services reject documents from certain countries or of certain types by policy, not by quality; the accepted-documents page will say so. If two clean re-scans are rejected and you cannot see why, stop re-uploading the same file — contact the service's support team and ask for the specific reason. Repeated identical uploads can trigger a temporary block on some platforms.

Common mistakes to avoid

Re-uploading the same file. If the scan was the problem, uploading it again changes nothing. Always re-scan.
Photographing the card on a screen. A photo of a photo adds moiré patterns and glare. Scan the physical card itself.
Using a black-and-white scan. Colour matters for security features and photo matching. Keep the scan in colour.
Ignoring the size limit. A 20 MB PDF that the portal silently downsamples can come out unreadable. Stay under the stated limit.
Uploading someone else's document. KYC verifies the account holder. An ID in another person's name will always be rejected — and can get the account flagged.

Frequently asked questions

Why did my ID get rejected even though the photo looks clear?
The usual hidden causes are a cropped edge, an expired card, or a name that does not match the account exactly. Check those three before re-scanning.

How many times can I retry a KYC upload?
Most services allow several attempts, but repeated identical uploads can trigger a temporary block. Fix the problem, re-scan, and only then upload again.

Does the file format matter for KYC?
Yes — upload the format the portal asks for, usually PDF or JPG, and stay under its size limit. A format the system cannot read is rejected outright.

What if my ID is expired?
Renew it first. No scan of an expired document passes KYC, however clear it is.

Who do I contact if my scan keeps getting rejected?
The service's support team. Ask which specific check failed — glare, edges, expiry, or name mismatch — so you can fix exactly that.
