To open a bank account, a person will usually need to show a form of identification such as a passport or a driver’s licence or a recognised identity card as well as proof of address.
Er mwyn agor cyfrif banc, fel rheol bydd angen i unigolyn ddangos dogfen i brofi pwy ydyw megis pasbort neu drwydded yrru neu gerdyn adnabod cydnabyddedig, yn ogystal â phrawf o'i gyfeiriad.
