Area Code 6422 – North Cotabato

Overview of Area Code 6422

Area code 6422 is a geographic National Destination Code (NDC) assigned to the province of North Cotabato in the Philippines, under the country calling code +63. This code is part of the Philippine numbering plan administered by the National Telecommunications Commission (NTC) and follows ITU-T E.164 recommendations. It serves the province's capital, Kidapawan City, and the municipalities of M'lang, Midsayap, Pigcawayan, and other surrounding areas. The code is used for fixed-line (PSTN) services, including both analog and digital landlines, as well as some fixed wireless and VoIP-based local services.

Dialing Formats

When calling a North Cotabato landline from within the Philippines (outside the area code), you must dial the trunk prefix 0, followed by the area code and the local subscriber number. The local subscriber number typically consists of 7 digits, making the complete national significant number (NSN) 10 digits (0-6422-XXX-XXXX). For example, a local number might be 123-4567, which would be dialed as 0-6422-123-4567 from other parts of the country.

For international callers, the format is +63 6422 XXX XXXX (or +63 6422 XXX-XXXX). The leading '0' is omitted, and the plus sign represents the international access prefix. For instance, to call a North Cotabato number from abroad, you would dial +63 6422 123 4567.

Geographic Coverage and Administration

North Cotabato is located in the SOCCSKSARGEN region (Region XII) on the island of Mindanao. The area code 6422 is part of the larger 64xx range assigned to the province. The province is subdivided into 17 municipalities and 1 component city (Kidapawan). The NTC has designated this code for the province's public switched telephone network (PSTN) and is also used by some local Internet Service Providers (ISPs) offering fixed wireless telephony.

Overlay and Numbering Considerations

Currently, there is no overlay code for 6422; the province uses a single area code. However, as demand for fixed-line services grows, the NTC may introduce additional digits or overlay codes in the future. Subscribers in North Cotabato can dial local calls within the same area code using only the 7-digit number (without the area code). For calls to other area codes, the 0-NDC format is required.

Caller Instructions

• Local callers (within North Cotabato): Dial the 7-digit subscriber number directly.
• National callers (from other Philippine provinces): Dial 0-6422-XXX-XXXX.
• International callers: Dial your country's exit code, then 63 (Philippines country code), then 6422, then the 7-digit number. Example: +63 6422 123 4567.

Ensure you replace 'XXX' with the actual local number. Always confirm the number of digits with your service provider, as some older lines may have fewer digits.
