What is a country calling code?

A country calling code is the numeric prefix you dial before a national phone number to route a call to a specific country. For example, +1 reaches the United States and Canada, +44 reaches the United Kingdom, and +91 reaches India. The plus sign stands in for the international access code your network uses.

How do I dial an international number correctly?

Start with your exit or access code (or the + symbol on a mobile), add the destination country code, then the area or city code without its leading zero, and finally the local subscriber number. So a London line looks like +44 20 7946 0000.

What does the plus (+) sign mean in a phone number?

The + is a universal placeholder for the international dialing prefix. Saving numbers in +country-code format means they connect from any country without editing the access code, which is why it is the recommended way to store contacts.

Why do the United States and Canada share the country code +1?

Both countries belong to the North American Numbering Plan, a shared system that also covers several Caribbean nations. They use the same +1 country code but are separated by distinct three-digit area codes.

Do I need to remove the leading zero from a phone number when calling internationally?

Usually yes. Many countries print a trunk prefix, often a 0, for domestic calls. When dialing from abroad you drop that leading zero after the country code. For example, a UK mobile written as 07700 900000 becomes +44 7700 900000.

Is WhatsApp the best channel to warm up a Bangladeshi contact before a letsdial call?

WhatsApp and imo are both popular in Bangladesh, with WhatsApp dominant among business users and imo widely used by working-class and overseas diaspora communities. For B2B outreach, WhatsApp is the safer default for pre-call messages before placing your letsdial call. For diaspora-to-family calling, imo messaging followed by a letsdial voice call is a common workflow.

What time zone does Bangladesh observe, and are there any DST adjustments?

Bangladesh observes Bangladesh Standard Time (BST, UTC+6) with no daylight saving time adjustments, providing a stable and predictable offset year-round. BST places Dhaka 30 minutes ahead of Kolkata (India, IST UTC+5:30) and 2 hours ahead of Pakistan (PKT UTC+5). For UK callers, Bangladesh is 6 hours ahead in winter, making afternoon UK calls align with Bangladeshi working hours.

Does Bangladesh follow a Sunday–Thursday business week?

Many Bangladeshi businesses and government offices traditionally operated Sunday through Thursday with Friday–Saturday as the weekend. However, the government shifted to a Saturday–Sunday weekend in 2023, making Monday through Friday the official work week for public sector employees. Private sector practices may still vary — always confirm your specific contact's schedule when arranging letsdial calls.

What are the main area codes in Bangladesh I should know for letsdial calls?

Dhaka uses area code 2 (domestic 02) and is by far the most commercially important, as Bangladesh's capital and economic hub. Chittagong uses 31, Sylhet uses 821, Khulna uses 41, and Rajshahi uses 721. For businesses targeting Bangladesh's garment and textile industry (headquartered in Dhaka and Chittagong), a letsdial virtual number with the 02 Dhaka code is the most strategically valuable.

Can letsdial support calling Bangladeshi overseas workers who use international SIMs?

Yes — Bangladesh has a large overseas worker population, particularly in the Middle East (Saudi Arabia, UAE, Qatar), Malaysia, and Italy. These workers often maintain Bangladeshi mobile numbers alongside local SIMs and communicate with family via WhatsApp or imo. letsdial's affordable international rates to Bangladesh (+880) and to Gulf countries (+966, +971) make it an ideal platform for businesses serving this diaspora corridor.
