Area code information

Timing unknown (2007?) - new national numbering plan

BTRC, the Bangladesh regulator, announced in April 2006 that a revised numbering plan would be introduced "shortly". No specific dates of implementation were indicated.

The plan features consolidation of area codes and standardisation of national number lengths to 10 digits (area code plus subscriber number, excluding prefixes).

International calling into Bangladesh is expected to be in the following formats:

International format  Service/carrier
--------------------  ---------------
+880 1x xxxxxxxx      mobile numbers
+880 2 T xxxxxxxx     BTTB (incumbent carrier)
+880 3x T xxxxxxx     other carriers
+880 4x T xxxxxxx     other carriers

In the above table, the T digit represents the consolidated zone code, identifying the region of Bangladesh:

Zone code   Area
---------   ----
2           central (Dhaka)
3           southeast (Chittagang)
4           southwest (Khulna)
5           northwest (Bogra, Rajshai)
9           northeast (Sylhet)

Overview of domestic dialling plan (as used within Bangladesh):

Prefix     Purpose
------     -------
0          national calling prefix
000        home country direct access (except 000800)

001        international prefix, toll-quality
002        international prefix, not toll-quality
0010 + cc  international carrier selection prefix, toll-quality
0020 + cc  international carrier selection prefix, not toll-quality
010xxx     value-added services
0101xx     internet access

102        ambulance
103        trunk enquiry
107x       emergency information
2 to 9     subscriber numbers within area

In the above table, "cc" represnets a 2-digit international carrier selection code, which does not begin with reserved digit '0'.

The general format for domestic long distance calling is:

0 + carrier code + zone code + subscriber number

Format          Carrier/service
------          ---------------
0 11 xxxxxxxx   mobile, PBTL

0 17 xxxxxxxx   mobile, Grameen Phones
0 18 xxxxxxxx   mobile, TMIB
0 19 xxxxxxxx   mobile, Sheba Mobile
