Method and system for platform attribution using digitized tokens

A method for determining attribution for a computing device, comprising:

• receiving, by a receiving device of a processing server, an attribution request from a third party entity, wherein the attribution request includes at least a specific computing device identifier and an indication of an advertisement;
• identifying, by a querying module of the processing server, a digital token number associated with the specific computing device identifier, wherein the association is based on a prior provisioning of the digital token number to a computing device associated with the specific computing device identifier;
• identifying, by the querying module of the processing server, a primary account number corresponding to the identified digital token number and one or more alternative digital token numbers also corresponding to the identified digital token number, where each of the one or more alternative digital token numbers were previously provisioned to a separate computing device unique to the one or more alternative digital token numbers and distinct from the computing device associated with the specific computing device identifier;
• identifying, by the querying module of the processing server, a transaction data entry related to an electronic transaction, wherein the transaction data entry includes transaction data and one of:
• the digital token number, the primary account number, and one of the one or more alternative digital token numbers;
• and
• electronically transmitting, by a transmitting device of the processing server, an attribution message to the third party entity, wherein the attribution message includes attribution of the indicated advertisement to the related electronic transaction.
