A Public Safety Access Point (PSAP) administration system is provided for safely modifying data in a PSAP database. The system includes a GUI, a storage system, and a processing system. The processing system logs changes to a data portion and defines modified data fields and unmodified data fields. The processing system reads out and stores a safe copy of the data portion from the PSAP database. The processing system writes the data portion to the PSAP database after reading the safe copy. The processing system reads out a verification copy of the data portion written to the PSAP database and compares the unmodified data fields of the safe copy to the unmodified data fields of the verification copy. The processing system generates an alarm if the unmodified data fields of the safe copy are not identical to the unmodified data fields of the verification copy.
