How to Call Bangladesh from the US
How to call Bangladesh from the US: dial 011 + 880 + area code (no leading 0) + local number. Covers Dhaka, mobile prefixes, BST time zone, and business tips.
To call Bangladesh from the US, dial 011 + 880 + area code (drop leading 0) + local number. Dhaka mobile example: 011-880-1711-234567. Dhaka landline: 011-880-2-XXXXXXX. The 011 is the US international exit code; 880 is Bangladesh’s country code.
This guide covers every variant — mobile operators, city area codes, Bangladesh Standard Time math, calling costs, and what US businesses communicating with Bangladesh’s garment and IT sectors need to know. Sibling guide: how to call the UK from the US.
How to dial Bangladesh from the US
Follow these four steps from any US phone:
- Dial 011 — the US international exit code. Every international call from a US landline or mobile starts here. On a US mobile, press and hold
0to enter+, which substitutes for 011 automatically. - Dial 880 — Bangladesh’s country code, assigned by the ITU. The prefix is now
011 880(or+880on mobile). - Dial the area code without its leading 0. Bangladeshi area codes are written with a leading 0 domestically (Dhaka is
02, Chittagong is031). Drop that 0 when calling from the US. - Dial the local subscriber number, then press call.
The full pattern: 011-880-<area code without leading 0>-<local number>
| Number type | Local (Bangladesh) format | From US |
|---|---|---|
| Dhaka landline | 02-XXXXXXX | 011-880-2-XXXXXXX |
| Chittagong landline | 031-XXXXXX | 011-880-31-XXXXXX |
| Grameenphone mobile | 01711-234567 | 011-880-1711-234567 |
| Banglalink mobile | 01911-234567 | 011-880-1911-234567 |
Note: the domestic leading 0 is dropped in every case.
Bangladeshi area codes by major city and mobile prefixes
City area codes (landlines)
Bangladeshi landlines use area codes administered by the BTRC (Bangladesh Telecommunication Regulatory Commission). The code is written with a leading 0 domestically — always drop that 0 when dialing from the US.
| City | Area code (local) | Dial from US after 011-880 |
|---|---|---|
| Dhaka | 02 | 2 |
| Chittagong | 031 | 31 |
| Khulna | 041 | 41 |
| Rajshahi | 0721 | 721 |
| Barisal | 0431 | 431 |
| Sylhet | 0821 | 821 |
| Rangpur | 0521 | 521 |
Dhaka landlines have the longest local subscriber numbers — typically 7–8 digits — because the capital has the highest line density. Smaller cities have shorter local numbers. Always confirm the full number with your contact.
Mobile prefixes (all four operators)
All Bangladeshi mobile numbers begin with 1 after the country code. Each operator has its own sub-prefix block:
| Operator | Domestic prefix | Dial from US after 011-880 |
|---|---|---|
| Grameenphone | 017x | 17x |
| Robi | 018x | 18x |
| Banglalink | 019x | 19x |
| Teletalk | 015x | 15x |
A full Grameenphone mobile number in domestic format: 01711-234567. From the US: 011-880-1711-234567. The pattern is identical for all four operators — drop the leading 0, the rest follows.
How Bangladeshi numbering works
Bangladesh’s phone numbering is regulated by the BTRC (Bangladesh Telecommunication Regulatory Commission) under Ministry of Posts, Telecommunications and Information Technology oversight. The ITU assigned Bangladesh country code +880.
The domestic numbering plan separates landlines and mobiles by structure. Landlines carry geographic area codes (2–4 digits) followed by variable-length local numbers. Mobile numbers are structured as a 2-digit operator prefix (17, 18, 19, 15) plus a 8-digit subscriber number — totaling 10 digits after the country code.
Bangladesh currently has four licensed mobile operators: Grameenphone (majority owned by Telenor), Robi (majority owned by Axiata), Banglalink (owned by VEON), and Teletalk (state-owned). Combined subscriber base exceeds 180 million as of 2026.
Time zones — Bangladesh Standard Time (BST)
Bangladesh Standard Time is UTC+6. Bangladesh does not observe daylight saving time — the UTC+6 offset is fixed year-round, which simplifies scheduling math.
| US time zone | Offset to BST | 9 AM local = BST |
|---|---|---|
| Eastern (ET) | +11h | 8:00 PM BST |
| Central (CT) | +12h | 9:00 PM BST |
| Mountain (MT) | +13h | 10:00 PM BST |
| Pacific (PT) | +14h | 11:00 PM BST |
For business scheduling: 7–9 AM Eastern catches Bangladesh at 6–8 PM BST — late business day but reachable. For US West Coast teams, 6–7 AM Pacific (8–9 PM BST) is the practical window. The FCC international calling guide recommends confirming recipient time before any international call.
US to Bangladesh calling costs
Cost depends heavily on method:
Per-minute carrier rates (no plan): Typically $0.10–$0.50 per minute to Bangladeshi mobile or landline. Major US carriers publish current Bangladesh rates in their international calling pages.
International add-on plans: $5–$15 per month for discounted per-minute rates, generally $0.05–$0.20/min depending on carrier and destination type.
VoIP providers: Generally the lowest cost for paid calls. DialPhone’s business phone plans include Bangladesh calling at competitive per-minute rates — no separate international add-on required. For teams with regular BD call volume, this eliminates per-call charge unpredictability.
Free internet-based options: WhatsApp, Viber, and Facebook Messenger are widely used in Bangladesh for voice and video calling over data. These require both parties to have internet access and the app installed. WhatsApp penetration is high in Dhaka’s business community.
See DialPhone pricing for current Bangladesh calling rates by plan tier.
Calling Bangladeshi mobile vs. landline — and WhatsApp use
The dialing format is the same whether you’re reaching a mobile or a landline — both use 011-880-<number without leading 0>. The distinction matters for cost and reliability:
Mobile numbers (starting 017x, 018x, 019x, 015x) connect over Bangladesh’s four mobile networks. Mobile coverage in Dhaka and Chittagong is strong; rural coverage varies by operator. Calls to Bangladeshi mobiles may cost slightly more than landlines on some US carrier rate tables.
Landline numbers reach fixed-line subscribers. Dhaka landlines (area code 2) are the most common for business contacts in the capital.
WhatsApp context: Bangladesh has very high WhatsApp adoption, particularly in urban business and garment industry circles. Many Bangladeshi business contacts prefer WhatsApp for initial outreach. For formal supplier or buyer communications, a voice call over VoIP still carries more professional weight — especially when your US number displays with STIR/SHAKEN A-attestation, signaling a verified legitimate business caller.
SMS to Bangladesh and the business use case
Standard SMS from a US number to a Bangladeshi mobile uses international format: +880 followed by the mobile number without the leading 0. US carrier rates for international SMS run $0.10–$0.25 per message.
The Bangladesh business context for US callers:
Bangladesh is the world’s second-largest garment and apparel exporter after China, responsible for roughly $47 billion in annual exports. Major US retailers and brands — including H&M, Gap, Walmart, and Target — source directly from Bangladeshi factories in Dhaka’s Ashulia and Gazipur export processing zones, and from Chittagong-based suppliers.
US purchasing managers, sourcing agents, and compliance officers at these companies place regular calls to Bangladeshi factory contacts, quality control teams, and logistics coordinators. Getting the dial format right — and calling at a Bangladesh-appropriate time — is a practical daily need for this segment.
Beyond RMG, Bangladesh’s IT outsourcing sector is growing. Dhaka-based software development firms increasingly work with US clients, adding a second high-volume segment of US-to-Bangladesh callers alongside the diaspora community (Bangladesh has large immigrant populations in New York, New Jersey, and Michigan).
DialPhone’s AI receptionist handles inbound calls from Bangladesh with STIR/SHAKEN A-attestation on outbound — the same verification that keeps US business numbers out of spam filters applies to calls originating from your DialPhone account to Bangladeshi contacts. See the STIR/SHAKEN explainer for background on call authentication.

FAQ
Calling Bangladesh FAQ
What is Bangladesh's country code?
Bangladesh's country code is +880, assigned by the ITU. From a US landline, dial the US exit code 011 first, making the full prefix 011 880. From a US mobile, you can dial +880 directly — the + replaces 011 automatically.
Do I drop the leading 0 when calling Bangladesh from the US?
Yes. Bangladeshi area codes and mobile numbers are written with a leading 0 in domestic format (for example, Dhaka is 02 locally and mobile numbers start 017x). That leading 0 is Bangladesh's domestic trunk prefix — used only when dialing inside Bangladesh.
From the US, replace the leading 0 with 011 880. So a Dhaka landline written as 02-XXXXXXX becomes 011-880-2-XXXXXXX from the US. Leaving the 0 in is the most common reason a US-to-Bangladesh call fails.
What is Bangladesh Standard Time?
Bangladesh Standard Time (BST) is UTC+6. Bangladesh does not observe daylight saving time, so the offset is constant year-round.
BST is 11 hours ahead of US Eastern Time, 12 hours ahead of Central, 13 hours ahead of Mountain, and 14 hours ahead of Pacific Time.
What are Bangladesh mobile number prefixes?
All Bangladeshi mobile numbers start with 1, making them easy to distinguish from landlines. The four mobile operators each have their own sub-prefixes: Grameenphone uses 017x, Robi uses 018x, Banglalink uses 019x, and Teletalk uses 015x.
From the US, all mobile numbers follow the same format: 011-880-1XXX-XXXXXX (drop the leading 0 from the 01XXX domestic prefix).
How much does it cost to call Bangladesh from the US?
Costs vary widely by method. Per-minute carrier rates without a plan typically run $0.10–$0.50/min to Bangladesh. International add-on plans from US carriers cost $5–$15/month for discounted rates.
VoIP providers are generally the cheapest paid option. DialPhone covers Bangladesh calling on business plans at competitive per-minute rates — no separate international add-on required. For frequent callers, especially US apparel importers sourcing from Bangladesh's RMG sector, a VoIP plan eliminates unpredictable per-call charges.
Can I send SMS to Bangladesh from the US?
Yes. Standard SMS from a US number to a Bangladeshi mobile works using international format: +880 followed by the mobile number without the leading 0.
US carrier rates for international SMS to Bangladesh are typically $0.10–$0.25 per message. WhatsApp is widely used in Bangladesh for messaging and voice calls. DialPhone supports SMS to Bangladesh for business communication.
Why do Bangladesh landline numbers vary in length?
Bangladeshi landline numbers have variable total length depending on the region. Dhaka (area code 2) uses longer local subscriber numbers — up to 8 digits — because it has the densest concentration of lines. Smaller cities and rural areas have shorter local numbers.
The BTRC (Bangladesh Telecommunication Regulatory Commission) manages the national numbering plan and has been expanding number capacity in major cities. Always verify the full number with your contact rather than assuming a fixed length.
What is the best time to call Bangladesh from the US?
BST is UTC+6 — 11 hours ahead of US Eastern. Bangladesh has no daylight saving time, so this gap is constant year-round.
For business calls, 7–9 AM Eastern Time reaches Bangladesh at 6–8 PM BST — the tail of the business day but still reachable. Morning Pacific calls (6 AM PT = 8 PM BST) can also work. Avoid calling after 10 AM Eastern — that is 9 PM or later in Bangladesh.
