Colombo postal codes

Colombo City is divided into 15 main postal zones, numbered from Colombo 01 to Colombo 15. Each zone is assigned a unique five-digit postal code ranging from 00100 to 01500. These postal codes cover various urban districts including Fort (Colombo 01), Pettah (Colombo 11), Bambalapitiya (Colombo 04), and Wellawatte (Colombo 06). Used for mail sorting and navigation, these codes also help distinguish different administrative and commercial areas within the city. Colombo’s urban layout, with each zone clearly demarcated, supports efficient postal services and logistics operations in Sri Lanka’s bustling commercial capital.

Colombo Outer Suburb Postal Codes

Colombo’s outer suburbs use distinct postal codes separate from the main Colombo 01–15 zones. These areas include suburbs like Battaramulla (10120), Athurugiriya (10150), Angoda (10620), and Avissawella (10700). Postal codes for these suburbs generally begin with “10” or “11” and extend into more residential and semi urban regions surrounding Colombo City. These areas are important for housing, government offices, and growing commercial zones. Having separate postal codes helps ensure accurate mail delivery, local identity, and administrative organization. The suburb codes also reflect Colombo’s geographic expansion and its networked relationship with satellite towns and municipalities.
