> [@Megha\_Kmphasis](#): > > 1358e94d-3472-4ff1-bb65-52c713b2b6ef Hi @Megha_Kmphasis , An SSN cannot be modified/updated on a `Verified Customer` record that already has a verified status. The user would need to be placed in a retry status in order to retry verification with the new identity information (which would require you to reach out to Dwolla). I included details in the thread below with regards to what fields can be updated on the various customer types. For personal Verified Customer records, only limited contact information can be updated. > [@Updating Customers - Do all values need to be provided](https://discuss.dwolla.com/t/updating-customers-do-all-values-need-to-be-provided/5976): > > Apologies if this is in the documentation, I wasn’t able to find it. When updating a customer, do I need to provide all the values, or just the ones I’m updating. Simplified example - say I create a customer with: { "firstName": "Jon", "lastName": "Doe", "email": "jdoe@gmail.com" } and I want to update the name from Jon to John. Do I need to pass in { "firstName": "John", "lastName": "Doe", "email": "jdoe@gmail.com" } or { "firstName": "John" } Please let me know if you have any follow up questions or if I can provide additional clarification! --- _[View the full topic](https://discuss.dwolla.com/t/why-dont-i-update-customer-using-sandbox-api/6877)._
