How To Call Bangladesh From USA: Updated For 2025

Quick Answer

To call Bangladesh from the United States:

• Landline: 011 + 880 + Area Code (1-4 digits) + Local Number (6-8 digits)
• Mobile: 011 + 880 + Mobile Number (10 digits, e.g., 1X XXXX XXXX)

Examples:

• For a Dhaka landline (Area Code 2): 011 + 880 + 2 + NNNN XXXX
• For a Bangladeshi mobile phone (e.g., Grameenphone prefix 17): 011 + 880 + 17XX XXX XXX

Bangladesh is on Bangladesh Standard Time (BST), UTC+6, and does not observe daylight saving. This is typically 10-11 hours ahead of US Eastern Time (ET), depending on US DST.

Understanding Bangladeshi Phone Numbers

Bangladeshi phone numbers use the country code +880. When dialing internationally, the leading 0 from a domestic area code or mobile prefix is dropped.

Landline Numbers

• Format from US: 011 + 880 + Area Code (1-4 digits) + Subscriber Number (6-8 digits)
• The total National Significant Number (NSN) length after +880 for a landline is typically 9 to 10 digits. For Dhaka (area code 2), a common format is +880 2 NNNN XXXX.

Mobile Numbers

• Format from US: 011 + 880 + Mobile Prefix (2 digits, e.g., 1X) + Subscriber Number (8 digits)
• Bangladeshi mobile numbers are 10 digits long after the country code +880 and start with a 1X prefix (e.g., +880 17XX XXX XXX).

Bangladeshi Area Codes (Fixed Lines)

When calling a landline in Bangladesh from the US, dial 011 + 880, then the area code (dropping any leading '0' used for domestic calls), followed by the local subscriber number. The total number of digits after +880 for landlines is generally 9 or 10.

Bangladeshi Mobile Phone Prefixes

Bangladeshi mobile phone numbers are 10 digits long after the +880 country code. They begin with a 2-digit mobile network operator prefix, always starting with `1`.

*Mobile Number Portability (MNP) allows subscribers to keep their number when changing operators, so the prefix does not always indicate the current service provider. The 'X' represents further digits of the subscriber number.

Time Difference

Bangladesh operates on Bangladesh Standard Time (BST), which is UTC+6. Bangladesh does not observe Daylight Saving Time.

The time difference compared to the US East Coast (ET):

• When the US is on Eastern Daylight Time (EDT, UTC-4, typically March to November): Bangladesh is 10 hours ahead of ET. (e.g., 12 PM EDT is 10 PM in Bangladesh).
• When the US is on Eastern Standard Time (EST, UTC-5, typically November to March): Bangladesh is 11 hours ahead of ET. (e.g., 12 PM EST is 11 PM in Bangladesh).

Bangladesh's Phone System

Bangladesh has a rapidly growing telecommunications sector, regulated by the Bangladesh Telecommunication Regulatory Commission (BTRC). The mobile market is highly competitive with several major operators including Grameenphone, Robi Axiata, Banglalink, and the state-owned Teletalk. These operators have achieved extensive network coverage across the country, offering 2G, 3G, 4G/LTE, and increasingly, 5G services. The fixed-line infrastructure is primarily managed by the Bangladesh Telecommunications Company Limited (BTCL), with several private PSTN operators also active. Bangladesh is connected to international submarine cable systems for internet bandwidth, and mobile number portability (MNP) has been implemented.

Best Times to Call

Considering Bangladesh is 10-11 hours ahead of US Eastern Time (ET):

• Calls from the US ET zone are best made in the evening or very early morning. For example, 8 PM - 11 PM ET would correspond to 6 AM - 9 AM or 7 AM - 10 AM the next day in Bangladesh.
• Alternatively, calling from 7 AM - 9 AM ET would reach Bangladesh in their late afternoon/early evening (5 PM - 8 PM or 6 PM - 9 PM BST).
• Typical business hours in Bangladesh are Sunday to Thursday (with Friday and Saturday being the weekend), from around 9:00/10:00 AM to 5:00/6:00 PM BST.
