Mobile area codes are three digits long and always start with the number 9, although 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 dialing format is always observed when using a mobile phone. Therefore, mobile phone numbers always have the format "+63 912 345 6789" for international callers and "0912 345 6789" 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 is exhausted, but this might not be the case if the next code is already in use. Starting October 21, 2020,
Sun's prepaid service was merged and rebranded into Smart Prepaid, leaving its postpaid service under "Sun" branding. Beginning March 2021,
Dito Telecommunity launched new mobile number prefixes: 895, 896, 897, 898, 991, 992, 993 and 994, assigned to Dito Prepaid, Dito Postpaid and Dito WiFi Prepaid. On April 11, 2022, PLDT and Smart announced the merger of Sun's postpaid service with Smart Postpaid, retiring all Sun Postpaid plans by April 25, 2022. Potential subscribers were encouraged to opt for Smart Signature plans, while existing Sun subscribers could continue with their plans or upgrade. The Sun Cellular brand was phased out in favor of the Smart brand. In May 2023, Globe Telecom maintained its mobile number prefixes: 954 for Globe At Home Prepaid WiFi, 952 and 953 for
TM, and 976 for
GOMO. That same month, Smart Communications introduced the 962 prefix for Smart (Prepaid, Postpaid, and Bro Prepaid), while keeping the prefixes 981 and 985 for
TNT, and 964 for Smart Bro Home WiFi Prepaid (formerly PLDT Home WiFi Prepaid) and TNT. Sometime in August 2025,
Smart Communications reintroduced the 925 prefix in time for the launch of its app-based
MVNO brand KiQ. The said prefix was used by its former brand
Sun Cellular for its prepaid, postpaid and Sun Wireless Broadband services. However, several blocks from this prefix are currently being utilized by Smart for its prepaid and postpaid services. In November 2025,
Dito Telecommunity introduced the 924 prefix for Dito Prepaid, Dito Postpaid and Dito WiFi Prepaid. Area codes are grouped by the provider with no single contiguous block of codes for a single provider. The companies and their respective area codes are listed below: ==See also==
