Systems and methods which provide for allocation of tokens, such as may be used for tracking number dissemination, for shipment document processing are described. Embodiments operate to allocate tokens to the various shipping document processing systems for their use by the respective document processing systems. The various shipping document processing systems may be enabled to independently perform shipping document processing for extended periods of time (e.g., days, weeks, etc.) using their respective allocations of tokens, such as to use the tokens, including reuse of the tokens over time, without overlap (e.g., without introducing overlapping instances of tracking numbers). Logic of shipping document processing systems record use time information (e.g., a date and/or time of use of a token or tokens) in association with their use of tokens of their allotment, wherein the use tokens from the allocations is in accordance with last use time information.

Token allocation for distributed shipping document processing

In certain embodiments, cryptographic-chain-based verification of postage transaction records may be facilitated. In some embodiments, a customer computer system may obtain a customer private key associated with a customer from a secure local storage at the customer computer system. The customer computer system may obtain (i) a first vendor digital signature derived from a first postage transaction record and (ii) a second postage transaction record. The customer computer system may create a customer digital signature based on (i) the customer private key, (ii) the first vendor digital signature, and (iii) the second postage transaction record. The customer computer system may provide the customer digital signature to a vendor computer system associated with the postage vendor, and, in response, obtain a second vendor digital signature from the vendor computer system, wherein the second vendor digital signature is based on (i) a vendor private key associated with the postage vendor and (ii) the customer digital signature.
