Bangladesh phone number validator
How the phone number format works
- Format
- Bangladesh phone number in national or international (+880) format
- Example
- +8801812345678
Things to watch for
- Accepts national or international (E.164, e.g. +880...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Bangladeshi mobile number is 11 digits in local form — 01, an operator digit, and eight more digits, e.g. 01812345678 — which becomes +8801812345678 once the leading 0 is dropped for international dialing. Mobile is by far the dominant way Bangladeshi phone numbers get collected today, from mobile financial services sign-ups to SMS-based order confirmations, which is exactly where a mistyped digit costs the most.
How this validator works
Type the number either in local form (01812345678) or full international form (+8801812345678); the check runs through Google’s libphonenumber library entirely in your browser, confirming the 11-digit local length, the 01 mobile prefix, and a valid operator digit — nothing is sent to a server. Landline numbers in Bangladesh follow a different, area-code-based structure (Dhaka’s area code is 2) with a different total length, so the validator distinguishes the two rather than applying one blanket digit-count rule.
What a pass doesn’t tell you
A pass means the number is shaped like a real Bangladeshi mobile or landline number — it says nothing about whether the SIM is currently active, which is especially relevant in a market where prepaid numbers get recycled after a period of inactivity.
Scope: this catches formatting mistakes — a missing 01, a wrong digit count, a leftover 0 after +880 — before a number reaches an SMS gateway or a signup form. It is not a network or line-status check.

phone number FAQ
How many digits does a Bangladeshi mobile number have?
Eleven digits in local form, always starting with 01 followed by an operator digit (3 through 9) and eight more digits — for example 01812345678. In full international form the leading 0 is dropped: +8801812345678.
Does a valid result mean the Bangladeshi number is currently in use?
No. It only confirms the digit count and prefix match a real Bangladeshi mobile pattern. Bangladesh has a large prepaid, SIM-swapping mobile market, so a correctly formatted number can easily be inactive, reassigned, or simply unreachable — this tool has no way to check that.
Why does my number fail when it has 11 digits but starts with 02 or 03?
Bangladeshi mobile numbers must start with 01, not any other combination — 02, 03, and similar prefixes belong to landline area codes (Dhaka is 02) instead, which follow a different length and structure entirely.
