Resource provider account token provisioning and processing

A method comprising:

• receiving, by a token issuer server computer, a token request message including a first identifier from a token requestor;
• analyzing, by the token issuer server computer, the first identifier;
• determining, by the token issuer server computer and based on the analyzing, that (1) the first identifier is associated with a resource provider account that is exclusive to the resource provider, and (2) the first identifier is in a first format that is ineligible for tokenization and provisioning on a digital wallet of a user device;
• transmitting, by the token issuer server computer, a universal identifier request to a resource provider processor system, wherein the universal identifier request includes the first identifier and requests a universal identifier corresponding to the first identifier;
• receiving, by the token issuer server computer, the universal identifier corresponding to the first identifier from the resource provider processor system, wherein the universal identifier is in a second format that is eligible for tokenization and provisioning on the digital wallet of the user device, wherein the second format is attributed to the resource provider processor system such that the resource provider processing system is identifiable based at least on the second format;
• generating, by the token issuer server computer, a token for the universal identifier, wherein the token represents the universal identifier;
• storing, by the token issuer server computer, a mapping between the token and the universal identifier at a token vault;
• and
• transmitting, by the token issuer server computer, the token to the token requestor, wherein the token is provisioned on the digital wallet stored on the user device associated with an account holder of the resource provider account.
