Abstract: A method includes receiving a lockbox transaction order associated with an account of the provider from a first user device where the lockbox transaction order includes a requested transaction and a desired transaction location, validating whether the requested transaction can be completed at the desired transaction location, determining a physical lockbox associated with the provider from a plurality of physical lockboxes at an alternative lockbox transaction location based on determining that the lockbox transaction order cannot be completed at the desired transaction location, transmitting an indication to a user device indicating that the requested transaction can be completed at the alternative lockbox transaction location, preparing the physical lockbox for the requested transaction, and authenticating a user at the physical lockbox where authenticating the user at the physical lockbox enables the physical lockbox to unlock and become accessible by the user.
