Area Code 64 – La Louvière

Overview of Belgian Geographic Numbering

In the Belgian public switched telephone network (PSTN), geographic numbers are assigned according to the ITU-T E.164 standard and are structured as: +32 (country code) followed by a National Significant Number (NSN) that includes a one-digit zone and a two-digit National Destination Code (NDC). The prefix 064 is the NDC for the La Louvière area, located in the province of Hainaut, Wallonia. This code is part of the historic Belgian numbering plan, where the leading '0' is used for domestic trunk prefix, and the '64' identifies the geographic routing area.

Geographic Coverage and Administrative Jurisdiction

The 064 area code serves the city of La Louvière and its surrounding municipalities, including but not limited to: Binche, Morlanwelz, Estinnes, and Manage. La Louvière is a major urban center in the Centre region of Hainaut, known for its industrial heritage and the UNESCO-listed hydraulic boat lifts. The numbering area is administered by the Belgian Institute for Postal Services and Telecommunications (BIPT), which oversees the allocation of geographic numbers to operators.

Dialing Formats and Caller Instructions

For local callers within Belgium, the number is dialed as 064 XX XX XX (including the trunk prefix '0'). For international callers, the format is +32 64 XX XX XX (without the leading '0'). For example, a local call to a La Louvière subscriber would be dialed as 064 12 34 56, while an international caller would dial +32 64 12 34 56. When dialing from a mobile phone within Belgium, the same domestic format applies, but it is advisable to use the international format (+32 64 ...) for clarity, especially when roaming.

Numbering Plan and Overlay Considerations

Belgium does not use area code overlays; each geographic area has a unique NDC. The 064 code is not subject to overlay, and the number length is fixed at 8 digits for the subscriber number (including the NDC) when dialed domestically, or 9 digits when including the country code internationally. The BIPT has implemented number portability, allowing subscribers to retain their geographic number when changing operators, but the number remains tied to the geographic location of the original exchange.

Regulatory and Technical Notes

Geographic numbers in Belgium are primarily used for fixed-line services, but they can also be used for VoIP services that are registered to a physical address in the area. However, since 2015, BIPT has allowed the use of geographic numbers for nomadic VoIP services under certain conditions, though the number's geographic association remains for emergency services routing. Callers should note that calls to 064 numbers are charged according to the caller's operator tariff, typically at a standard national rate.
