Customers who cannot receive an authentication code, such as customers who have PHS (Personal Handy-phone System), customers who only have a landline and customers who use MNP (mobile number portability) can send us “proof of payment of telephone charges ” for their registered phone number. Zaif will confirm and complete the code registration process on their behalf.
*The proof of payment of telephone charges needs to be a document similar to the ones in the links below, containing your name and your registered phone number on the bill. http://www.au.kddi.com/support/mobile/procedure/payment/paper/breakdown/billing https://www.nttdocomo.co.jp/binary/pdf/support/procedure/list/certificate_of_payment.pdf
*If the size of the data is small (under 1MB), you can send the proof of payment documentation as a reply to a confirmation email from our Support Center, or you can upload the documentation to the Identity Verification page.
