Fixed-line area codes - Philippine area codes for fixed-line or landline telephones are fixed at two digits, excluding Metro Manila, the province of Rizal and the towns of Obando in Bulacan and San Pedro,Laguna, which use the area code - 2 - . Some smaller carriers concentrated within a specific geographic area may issue four- or five-digit area codes, but these are being phased out in favour of the standard two-digit area codes.
