Aspects and examples are disclosed for facilitating transactions with an interactive computing environment provided by a host system. In one example, a processing device receives a data network identifier or other identifier from an interactive computing environment. The data network identifier or other identifier can be associated with a mobile device conducting a transaction with the interactive computing environment. The processing device can also obtain a credential associated with the mobile device using the data network identifier. The processing device can additionally retrieve identification information from a credit file associated with the credential. The identification information can be useable for completing the transaction. The processing device can further transmit the identification information to a host server system executing the interactive computing environment.
