Telephone numbers in the Philippines


Telephone numbers in the Philippines follow an open telephone numbering plan and an open dial plan. Both plans are regulated by the National Telecommunications Commission, an attached agency under the Department of Information and Communications Technology.
The Philippines is assigned an international dialing code of 63 by ITU-T. Telephone numbers are fixed at eight digits for area code 02, and seven digits for area codes from 03X to 09X, with area codes fixed at one, two, or three digits. Mobile phone numbers are always 10 digits.
When making long-distance calls in the Philippines, the prefix 0 for domestic calls and 00 for international calls are used.

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 cities of Bacoor in Cavite and San Pedro in 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.
Occasionally, a particular area may change area codes. For example, the City of Bacoor in Cavite has been included in the geographical coverage area of area code 2 per the National Telecommunications Commission's Memorandum Order No. 08-09-2011, although almost all fixed-lines in the city still use the old 46 area code due to the poor compliance of PLDT and Globe to the said memorandum order. PLDT's response to the memorandum order is the release of its "Call All Manila SIM", an exclusive wireless landline service for Bacoor residents, however the Barangay Molino VII and Sitio Malipay in Molino IV now use area code 2.
Sometimes area codes are shared by a number of local government entities to maximise their use. Some area codes are shared by multiple provinces, as is the case for former sub-provinces like Guimaras and Iloilo; newly carved provinces like Zamboanga Sibugay and Zamboanga del Sur; or provinces with small populations like Marinduque and Quezon. In extreme cases, area codes are shared across an island like in Leyte and Samar, or even entire regions, such as with the Cordillera Administrative Region. In order to identify the call's point of origin, the three-digit telephone exchange prefix is checked.
Since the Philippines employs an open dial plan, telephone numbers dialled within a given area code do not require the area code, excluding calls made from mobile phones or pay phones. When dialling other area codes, the domestic long distance access prefix 0 is added, but when dialling from overseas, the domestic prefix is not included. As such, a typical telephone number in Metro Manila and Rizal would look like this:
Since October 6, 2019, all telephone numbers under area 2 had been migrated to eight digits as mandated by the National Telecommunications Commission per Memorandum Order No. 10-10-2017 in order to address the insufficient number of assignable local exchange codes.
The maintenance for the migration from the usual 7-digit number to 8-digit is from 12:00:00 AM to 04:59:59 AM.
It lasted five hours of disconnection on telephones and it will also affect subscription-based virtual telephone numbers, SIM card-based Telephone Service, #MyNumber, FEX Lines, SIP Trunks, ISDN and Vanity Numbers, Including virtual numbers like short-digit numbers , Toll Free and Premium numbers such as embassy hotline and 1900 service hotline.
Since October 6, 2019 5 AM, the following telephone number format to be followed:
NTC has assigned the following Public Telecommunications Entity identifiers:
Areas are grouped into seven broad areas determining the first digit of a given area code. These areas and their accompanying area codes are listed below:

Area 2 – National Capital Region, Rizal and Surroundings

Mobile phone area codes

Mobile area codes are three digits long and always start with the number 9, although recently new area codes have been issued with 8 as the starting digit, particularly for VOIP phone numbers. However, the area code indicates the service provider and not necessarily a geographic region. Unlike fixed-line telephones, the long-distance telephone dialling format is always observed when using a mobile phone. Therefore, mobile phone numbers always have the format "+63 966 164-5400" for international callers and "0 966 164-5400" for domestic callers.
Some of the first area codes to be assigned for mobile phones were 912 for Mobiline/Piltel, 915 for Islacom, 917 for Globe Telecom, 918 for Smart Communications, and 973 for Express Telecom. As service began growing rapidly since the 1990s, new codes have been added to meet demand as existing codes have since been exhausted. Newer codes often come immediately after the last code exhausted, but this might not be the case if the next code is already in use. As of March 2020, Globe Telecom launched a new mobile number prefix, 954 assigned to Globe At Home Prepaid. Also, Smart Communications launched a new moblie number prefixes, 951 assigned to TNT and 931 assigned to Sun Prepaid.
Areas codes are grouped by provider with no single contiguous block of codes for a single provider. The companies and their respective area codes are listed below:
The list of prefixes is updated as of March 2020.
