Postal services in this part of Kakinada district run through the Kakinada sub-division, one of several offices set up to handle the area’s mix of urban and semi-urban addresses. Like most Indian PIN codes, this one exists purely as an administrative and logistical tool — it does not indicate a single town or landmark, but rather a defined delivery zone that India Post uses to route mail efficiently across a cluster of villages, neighborhoods, or municipal wards.
The PIN code itself follows India’s standard six-digit postal numbering system, introduced in 1972 to solve the problem of duplicate place names across different states. The first digit represents one of nine postal zones covering the country, the second and third digits narrow this down to a specific sorting district, and the final three digits identify the exact delivery office responsible for last-mile distribution. Understanding this structure is useful context for anyone trying to make sense of why certain PIN codes cluster together geographically.
For residents, businesses, and anyone filling out a form, this PIN code serves several everyday practical functions. Banks require it during account opening and KYC verification to confirm a customer’s registered address. E-commerce platforms use it to calculate delivery timelines and shipping charges, and to route parcels to the correct regional distribution hub before final delivery. Government departments rely on it for issuing documents tied to a specific jurisdiction, including ration cards, voter ID cards, and property records. Insurance companies and courier services also use the PIN code as a quick way to verify service availability in a given area.
Specific landmark, population, and historical data tied to this exact PIN code are limited in publicly available postal records, which tend to document administrative structure rather than local geography or culture. What is documented is the office hierarchy: there is no delivery post office listed for this PIN code within postal records.
