§ 120b.113. Accuracy standards for enhanced 911 database systems.
(a) The Master Street Address Guide (MSAG) is an information file prepared by a county that contains a list of all street names and address ranges within a county’s enhanced 911 service area.
(1) Associated with each street are:
(i) The low/high address ranges as well as a designation for odd, even or all numbers as appropriate.
(ii) Street directionals, such as N, S, E, W.
(iii) Street types such as ST (Street), RD (Road), LN (Lane).
(2) The MSAG may also contain a Public Safety Answering Point (PSAP) designation and the appropriate emergency service providers (police, fire and medical) assigned to each address range.
(b) A Local Exchange Carrier (LEC) customer database contains the billed customer’s telephone number, listed name and service address.
(c) After a county creates an initial MSAG, the county and the LEC shall perform a database validation process every 6 months by comparing LEC customer data with the MSAG data.
(1) When substantive database mismatches are detected during the validation process and are subsequently corrected to the extent that at least 95% of the LEC’s customer database matches the MSAG database, the MSAG database may be loaded into the 911 database management system of the LEC or of a different host LEC if applicable.
(2) When 100% street addressing has not taken place within a certain geographical area of a county, a partial county MSAG may be used where technically feasible as long as the data load has an accuracy rate of at least 95%.
(3) Every 6 months thereafter, a county and the LECs shall meet to review their databases to update and eliminate, insofar as possible, any substantive mismatches between the county’s MSAG and LEC’s customer database.
