The present disclosure relates to a computer-implemented method for tokenizing data in a distributed tokenization environment comprising a central token management system communicatively coupled to a plurality of clients, the method comprising: receiving, by each of the plurality of clients, a set of values from the central token management system such that each value in each set of values is not included in any other set of values; receiving, at a client, sensitive data to be tokenized; querying a token table associated with the client with a portion of the sensitive data to determine if the token table includes a token mapped to a value of the portion of the sensitive data, the token table storing a plurality of tokens each mapped to a different value; and responsive to a determination that the token table does not include a token mapped to a value of the portion of the sensitive data: generating a token unique to the client by selecting a value from the set of values received by the client from the central token management system; tokenizing the sensitive data using the generated token; and storing the generated token in the token table associated with the client.
