Banks participating in the DCM platform can encourage their users to add phone numbers as aliases to the Alias Database. At the same time, the rule "one phone number = one IBAN account " at any given time is always enforced.
A bank client can change the account number linked to their phone number (alias) at any time using the functionality of the bank’s mobile application.
If a user links a different account number to their phone number, the DCM platform will notify the previous bank about the change in the linked account number.
