Provide proof of identity and address. You may need to submit ID and address proof. For example, you may need to upload a copy of your passport or driving license, and a utility or phone bill. 

Activate your account and start banking. Once your application is approved, you will receive your account number, sort code, and debit card in the mail. You can activate your account online or by phone and start managing your money with online, mobile, or phone banking.
