Introduced on 15 August 1972 by Shriram Bhikaji Velankar, the 6-digit PIN code system standardizes mail sorting across India into 9 postal zones.

Digit 1: Zone

Indicates 1 of the 9 postal regions in India (1 & 2: North, 3 & 4: West, 5 & 6: South, 7 & 8: East, 9: Army Postal Service).

Digit 2: Sub-Zone

Determines the state or postal circle within that geographical zone (e.g. 56 is Karnataka, 11 is Delhi).

Digit 3: District

Represents the revenue sorting district within the postal circle where mail is concentrated.

Digits 4–6: Office

Designates the specific delivery post office (Head Office, Sub Office, or Branch Office).

Speed Post charges depend on the weight of the parcel and the distance between origin and destination PIN codes (Local, up to 200 km, 201–1,000 km, 1,001–2,000 km, or above 2,000 km). An 18% GST is applicable on all domestic Speed Post services. You can use our interactive Speed Post Rate Calculator to calculate the exact postage.
