Acceptable documents vary by country, although a passport scan is always acceptable and preferred. Please do not send blurry or illegible images, because then we have to ask you to try again. On a phone, tap where you want it to focus before taking the picture.
Format: Files need to be JPEGs or PNGs, in color, and smaller than 5MB. Sorry - we can not verify PDFs.
Orientation: rotate the image so that the ID is displayed right side up.
Front AND back: you should take a picture or scan both the front and the back of card-type IDs like drivers licenses. For a passport, scan the two pages with your photo and information.
