Automation and callbacks are not opposing approaches. Automated validation provides fast, independent checks, while a callback adds direct human confirmation when a telephone conversation is needed. Together, these controls help organisations verify supplier payment information more securely and efficiently.<\/p>\n\n\n\n
\n\n\n
Key Takeaways:<\/span><\/h3>\n\n- A callback is an outbound phone verification used to confirm a supplier\u2019s identity, payment request, or change of bank account details.<\/li>\n
- Callbacks should use a phone number obtained from a trusted, independent source.<\/li>\n
- Trustpair can perform callback verifications on behalf of its clients through its verification agents.<\/li>\n
- Automated bank account validation and callbacks are complementary controls, not mutually exclusive alternatives.<\/li>\n
- Combining automation with human-led verification makes payment security more scalable without removing the phone-based checks required for higher-risk situations.<\/li>\n
- A strong\u00a0supplier verification process<\/a> combines identity checks, account validation, documented procedures, and human confirmation when necessary.<\/li>\n<\/ul>\n\n\n
\n\n\nWhat is a call back procedure?<\/h2>\nA callback procedure is a phone-based verification process used to confirm that a payment request or change to a supplier\u2019s bank details is genuine. The organisation makes an outbound call to a trusted phone number and speaks with an authorised supplier contact.<\/div>\n\u00a0<\/div>\nThe purpose of a callback is to independently confirm the request, not simply to repeat information received by email. The person conducting the call should ask the supplier to state or confirm the relevant payment details and document the result before payment is released.<\/div>\n\u00a0<\/div>\nOrganisations can perform callbacks internally, or they can use a specialist service such as Trustpair to conduct the verification on their behalf. In both cases, the phone conversation remains an important part of the control.<\/div>\nCallbacks are especially useful when:<\/div>\n\n- A supplier requests a change to payment details.<\/li>\n
- A payment request is unexpected or urgent.<\/li>\n
- A new supplier is being onboarded.<\/li>\n
- The invoice or bank details do not match existing records.<\/li>\n
- The request contains unusual information or potential fraud red flags.<\/li>\n
- A payment requires additional human confirmation before approval.<\/li>\n<\/ul>\nFor broader guidance, see our article on how to verify bank transfer instructions<\/a>.<\/div>\n
