The numerical sequence employed to dial telephone numbers in Bangkok facilitates international and domestic telecommunications. This sequence is essential for connecting calls to landlines and mobile devices within the city’s geographical boundaries. As an example, when calling a Bangkok number from outside Thailand, the international dialing code for Thailand must be used, followed by the specified sequence for Bangkok, and then the local number.
The use of a specific numerical sequence offers several benefits, including efficient call routing and cost allocation for telecommunication providers. Historically, such codes have evolved alongside the expansion of telecommunications infrastructure, reflecting changes in population density and technological advancements. The assignment and management of these codes are typically overseen by national telecommunications regulatory bodies.
