When you order a certificate, you have the option to receive it as a PDF or certified document. If you choose to receive it as a PDF, your document will be sent to your e-mail address. If you choose to receive it as a certified document, your document will be sent to your address by cargo. Certified documents are more expensive than PDFs, but they may be required for certain situations (such as applying for a passport). Whichever option you choose, you can be confident that you will receive your certificate in a timely and efficient manner.
