Bangladesh পোস্ট কোড validator
How the পোস্ট কোড format works
- Format
- 4 digits
- Example
- 1000
Things to watch for
- Format-only check — does not confirm the পোস্ট কোড actually exists
- Always exactly 4 digits with no separators — one of the shortest postcodes in South Asia
- Dhaka GPO's central code is 1000; Bangladesh introduced its 4-digit postcode system in 1986, some years after independence
^[0-9]{4}$A Bangladeshi পোস্ট কোড (post code) is the 4-digit code Bangladesh Post uses to route mail — for example 1000 for Dhaka GPO. At just four digits, it’s noticeably shorter than most of its South Asian neighbors: India’s PIN code runs to six digits and Pakistan’s and Nepal’s postal codes both run to five. Anyone validating a Bangladeshi shipping address, a checkout form, or a spreadsheet of customer records needs the পোস্ট কোড in the right 4-digit shape before it’s trusted downstream.
With only four bare digits and no separator or letter to anchor against, a single dropped digit collapses one valid-looking code into another — there’s nothing in the string’s shape to signal the mistake.
How this validator works
This tool checks that the input is exactly 4 digits with no letters, spaces, or hyphens, entirely in your browser, with nothing sent to a server.
What a pass doesn’t tell you
A পোস্ট কোড carries no check digit, so matching the 4-digit shape is the most a client-side tool can confirm — not that Bangladesh Post has assigned it to a real thana or delivery office. Confirming that requires Bangladesh Post’s own postcode lookup.
Scope: this page and tool cover format validation only — not address lookup or confirming a পোস্ট কোড is currently in use.
পোস্ট কোড FAQ
How many digits does a Bangladeshi post code have?
Four — one of the shortest postal codes anywhere on this site. Dhaka's General Post Office sits at 1000, and codes climb from there by district and thana (sub-district).
Is Bangladesh's 4-digit code older or newer than India's 6-digit PIN code?
Newer: Bangladesh introduced its 4-digit postcode system in 1986, while India's neighboring 6-digit PIN system dates to 1972 and encodes far more postal-region detail per code. Bangladesh's has stayed short and unchanged since.
Does a correctly formatted পোস্ট কোড mean it actually exists?
No. This tool only confirms the string is 4 digits — it doesn't check it against Bangladesh Post's actual assignment list. Confirming a পোস্ট কোড is real, and seeing which thana it covers, requires Bangladesh Post's own postcode lookup.
