An accessible electronic system is provided for storing old and new electronic identifiers and for searching and matching the new and old electronic identifiers of an entity. The electronic system creates a bridge from the old to the new electronic identifiers. During a registration process a registrant may provide the system with a preferred electronic identifier in addition to a series of functional and/or non-functional electronic identifiers. During a searching process, if the searcher provides the system with any of the electronic identifiers provided to the system by the registrant, the system will return the preferred electronic identifier of the registrant.
