# Best practices for successful ID verification

Depending on what you use Link for, you may need to upload your ID to complete your identity verification.
## Before you begin
You’ll need:
* Your original, valid government-issued photo ID. A photocopy or an image of the document are not accepted.
* A device with a camera. If possible, use a mobile device, as mobile cameras typically produce higher-quality photos than webcams.
* A recent version of Chrome, Safari, or Microsoft Edge.
Make sure your ID:
* Is an accepted document type.
* Is current and not expired.
* Belongs to the person whose identity is being verified.
* Is not redacted, altered, or damaged.
## Tips for taking successful photos
Image quality affects verification success. Follow these recommendations when photographing your ID and face:
### Photographing your ID
* Place your ID on a flat surface.
* Make sure the entire document is visible. Don’t cover or block any part of it.
* Hold your device steady and allow the camera to focus.
* Make sure the image is clear and isn’t too dark or bright.
* Avoid shadows and glare.
* Use a color image.
* If uploading an existing image file, use `.png` or `.jpg`.
### Photographing your face
* Make sure your entire face is visible.
* Remove sunglasses, masks, and other accessories that obscure your face.
* Choose a location with soft, ambient lighting.
* Avoid strong overhead lighting that casts shadows on your face or ID.
* Don’t sit directly in front of a bright light, which can wash out your face or create glare.
## Troubleshooting
### My camera or webcam isn’t working
Confirm that your browser has permission to access your camera. If you previously blocked access, update the camera permissions in Chrome, Safari, or Microsoft Edge and try again.
