How do geographical and non-geographical phone numbers differ in [a particular region]?

Post by liza89 »

In Dhaka, Dhaka Division, Bangladesh, phone numbers can be broadly categorized into geographical and non-geographical numbers, each serving different purposes and having distinct characteristics:

Geographical Phone Numbers:

Association with Location: These phone numbers are directly linked to a specific geographical area, usually denoted by an area code. In Bangladesh, landline numbers assigned by the Bangladesh Telecommunications Company Limited (BTCL) traditionally follow this pattern.
Area Codes in Dhaka Division: The primary geographical area code for Dhaka city itself is 02. When dialing a landline number within Dhaka city, you would typically use 02-XXXX-XXXX. When calling from outside Dhaka but within Bangladesh, you'd use 0-2-XXXX-XXXX. Internationally, it's +880-2-XXXX-XXXX.
Other Districts in Dhaka Division: Different districts within the Dhaka Division have their own geographical area codes for landline numbers. For example, while not definitively listed in a single place in the search results, areas like Narayanganj, Gazipur, Manikganj, Munshiganj, Narsingdi, Tangail, and Kishoreganj would each have their own unique area codes for fixed-line connections. Callers would need to use the specific area code for that district when dialing a landline number there.
New BTCL Numbering: Newer BTCL landline albania mobile phone number list numbers follow a format like +8802XNN-NNNNNN, where 'X' represents a zone code within the broader 02 area code, further specifying a sub-region.
Non-Geographical Phone Numbers:

Not Tied to a Specific Location: These numbers are not associated with a particular geographic area code. They can be used from anywhere within the country and sometimes even internationally.
Mobile Phone Numbers: In Bangladesh, mobile phone numbers (starting with 013, 017, 019, etc.) are the most common type of non-geographical numbers. The initial digits (01X) indicate the mobile network operator (e.g., 017 for Grameenphone, 019 for Banglalink) rather than a specific geographic location. With Mobile Number Portability (MNP) introduced in 2018, subscribers can retain their mobile number even when switching operators.
Toll-Free Numbers: These numbers (often starting with 0800 or a similar prefix, though specific prefixes in Bangladesh need to be verified) allow callers to reach an organization without incurring any call charges. Government agencies and utility companies often use these for customer service.
Special Service Numbers (Short Codes): Numbers like 999 (emergency services), 333 (government helpline), 106 (Anti-Corruption Commission), and various other short codes for specific services are non-geographical and accessible nationwide.
IP Telephony (VoIP) Numbers: Numbers starting with +880-96XX-NNNNNN are typically assigned to licensed IP telephony service providers (IPTSPs). These numbers are not tied to a traditional geographic area code.
Key Differences Summarized:

Feature Geographical Phone Numbers Non-Geographical Phone Numbers
Location Linked to a specific geographic area/code Not tied to a specific geographic area
Examples (Dhaka) Landlines starting with 02 followed by local digits Mobile numbers (01X), Toll-free (e.g., 0800), Short codes (999, 333), VoIP (096XX)
