Various embodiments of systems and methods to provide pseudo internal numbering for uniquely and continuously numbering of legally bound documents are described herein. In one aspect, an external numbering range object (NRO) is generated in a computer system. The range of numbers assignable by the external NRO is split into a set of intervals based on a prefix. In another aspect, an internal NRO is generated corresponding to a subset of the intervals of the external NRO. The correspondence between the internal NRO and the subset of intervals is determined by a part of the prefix. In yet another aspect, the unique and continuous numbers generated by the internal NRO are correlated with the numbers in the intervals of the subset of intervals of the external NRO based on a correspondence between values of the prefix of the external NRO and a prefix of the internal NRO.
