Overview of Area Code 4422

Area code 4422 is a geographic National Destination Code (NDC) assigned to the province of Bulacan in the Philippines. It is part of the country's open dialing plan, where the NDC is used for both domestic and international calls. The code covers the central and eastern municipalities of Bulacan, including the provincial capital Malolos, as well as the towns of Guiguinto, Balagtas, Plaridel, Pulilan, Calumpit, Paombong, and Hagonoy. These areas form a contiguous zone within the Greater Manila Area's northern fringe, characterized by a mix of residential, commercial, and industrial developments.

Dialing Formats

When dialing a landline number within the Philippines, the standard format is 0-4422-XXX-XXXX (where X represents the subscriber's local number). For example, a local call from another province would be dialed as 0 4422 123 4567. However, if you are calling from within the same area code, you may omit the trunk prefix and area code, dialing only the 7-digit local number (e.g., 123 4567).

For international callers, the format is +63 4422 XXX XXXX (or +63 4422 123 4567). The leading '0' is dropped, and the country code for the Philippines (+63) is used. This format applies to both PSTN and VoIP calls.

Overlay and Numbering Considerations

Currently, area code 4422 does not have an overlay, meaning that the 7-digit local number length is standard. However, as the demand for landline numbers grows, the National Telecommunications Commission (NTC) may introduce overlays or migrate to an 8-digit local number format in the future. Subscribers should be aware that number portability is available for landlines, allowing users to retain their numbers when switching service providers within the same geographic area.

Caller Instructions

For local callers within Bulacan, simply dial the 7-digit number. For callers from other parts of the Philippines, use the trunk prefix '0' followed by the area code and local number. For international callers, always use the country code and omit the trunk prefix. It is also important to note that while VoIP services may route calls over IP, the dialing format remains the same as traditional PSTN.
