This page connects featured cities in Dhaka Division with their published or clearly qualified telephone numbering associations.
“Largest” refers to the priority city set used by this directory. It is not a live population ranking.
| City | Domestic area code | International prefix | Context |
|---|---|---|---|
| Dhaka | 022 | +880 22 | Dhaka is in BTRC’s Central Zone and uses featured BTCL geographic NDC 22, displayed domestically with trunk prefix as 022. |
| Gazipur | 022 | +880 22 | Gazipur District headquarters is listed in BTRC’s Central Zone; other parts of the district are assigned differently in the zonal table. |
| Narayanganj | 022 | +880 22 | Narayanganj District headquarters is listed in BTRC’s Central Zone; the zone table treats some surrounding territory separately. |
| Faridpur | 024 | +880 24 | Faridpur is administratively in Dhaka Division but is listed in BTRC’s South-West numbering zone and uses featured BTCL NDC 24. |
| Tangail | 029 | +880 29 | Tangail is administratively in Dhaka Division but is listed in BTRC’s North-East numbering zone and uses featured BTCL NDC 29. |
For a featured BTCL fixed line, dial domestic trunk 0 + the two-digit NDC + the eight-digit subscriber number. Remove only the initial 0 in international format: 022 becomes +880 22. Confirm the complete current number with the subscriber because legacy fixed-line numbers have been migrated in stages.

These pages cover the five complete BTCL geographic NDCs, not universal city codes. Other PSTN and IP-telephony operators combine their own network prefixes with the same zone structure and therefore use different NDCs. Each zone spans many districts, some administrative divisions cross numbering-zone boundaries, and migration from older local formats means a published address or business may still show a legacy number.
A code listed beside a city reflects a featured numbering association; it does not assert that every community in Dhaka Division uses that code or that the code stops at the administrative border.
This release includes 3 verified or clearly qualified code associations for the featured cities in Dhaka Division.
