PSGC 3rd Quarter 2017 Updates: Abolition of the Negros Island Region (NIR)

Reference Number: 


Release Date: 

Friday, October 27, 2017
The Negros Island Region (NIR) was abolished through Executive Order No. 38 – “Revoking Executive Order No. 183 (s. 2015) which Created a Negros Island Region and for Other Purposes”, signed by President Rodrigo Roa Duterte on 07 August 2017. The abolition of NIR reverted the provinces, cities, municipalities, and barangays of Negros Occidental and Negros Oriental to Region VI (Western Visayas) and Region VII (Central Visayas), respectively.
Per Philippine Standard Geographic Code (PSGC) updating procedures, any geographic-political unit in the country which reverted to its previous region/ province/ city/ municipality/ barangay will assume its former code. Thus, Negros Occidental and Negros Oriental shall be assigned their former codes 064500000 and 074600000, respectively. For the complete list of updated codes, the PSGC database and masterlist can be accessed and downloaded at
With the abolition of NIR, the total number of regions in the country is back to 17.
Inter-level As of 30 Sept. 2017 As of 30 June 2017
Regions 17 18
Provinces 81 81
Cities 145 145
Municipalities 1,489 1,489
Barangays 42,036 42,036


Meanwhile, per Section 10 of the 1991 Local Government Code, no division or alteration of boundaries of local government units shall take effect unless approved by a majority of the votes cast in a plebiscite in the political units directly affected. Said plebiscite shall be conducted within one hundred twenty (120) days from the date of effectivity of the law. Thus, the created seven (7) distinct and independent barangays in the City of Navotas through Republic Acts No. 10933, 10934, and 10935 signed in August 2017 pending the conduct of the required plebiscites are not yet included in the 3rd Quarter 2017 PSGC Updates. The plebiscites for the newly created barangays are scheduled to be held in December 2017.
