CHENNAI PIN Service Coverage Listing

This page lists 710 six-digit service PIN records in the CHENNAI, TAMIL NADU routing group. It is a service-data listing rather than an official postal-location directory: every row links to an individual PIN page where the Government postal mapping is used only when it supports a safe result. Start with the PIN code list if you know a routing or branch label, and use the exact checker when you already have all six digits.

Among the listed records, 152 include a DTDC branch detail, 152 currently satisfy the workbook-derived DTDC availability condition, and 531 are presented through the India Post (DTDC Network) path. These totals describe only this service-routing group. They do not turn a routing group into a delivery promise or postal jurisdiction; service is determined from the exact six-digit PIN record and can be unavailable for a particular PIN even when other records in the same group show a result.

The service-data status column reflects the current workbook-derived service record, not Government postal delivery status. Open an individual page when you need a focused view of one PIN, including its official postal office and delivery detail where the source provides it. For any booking or dispatch decision, confirm the customer’s full address and recheck the exact PIN near the time of shipment. The routing-group and related-PIN links are provided for browsing, while the lookup tool remains the authoritative customer-facing service check. This distinction matters when areas share a routing label but have different official postal jurisdictions. Treat the listing as a way to narrow the search and the exact result as the final service answer.
