## What the Mobile to Bank API does

Mobile to Bank returns the bank accounts associated with a given mobile number, drawing on records that link phone numbers to banking relationships. It turns a long, error-prone form field into a confirmation step.

This shortens onboarding noticeably. Rather than asking a customer to find their cheque book and type a sixteen-digit account number, you present the account you already resolved and ask them to confirm it.

## Where teams use the Mobile to Bank API

1.  Pre-filling bank details during digital lending journeys
    
2.  Reducing drop-off on account entry in mobile-first flows
    
3.  Cross-checking a declared account against ones already linked to the customer
    
4.  Detecting when an applicant supplies an account with no history against their number
    

## Frequently Asked Questions (FAQs)

Do I need the customer's consent?

Yes. This returns financial information tied to an individual, so collect and record explicit consent before you query it.

Will it always find an account?

No. Coverage depends on the number being linked in the source records. Treat a nil result as inconclusive rather than as evidence the customer has no bank account.

Does it confirm the account is active?

Not on its own. Follow it with a penny-drop or penny-less verification if you intend to send money to the account.
