Headquarters: Narasaraopeta. An inland district stretches from the Krishna-side plain toward the Nallamala-side dry interior. Locate this district first in relation to the coast, the Godavari or Krishna corridors, the Eastern Ghats or the Rayalaseema plateau. These physical belts often reveal why a crop, port, reservoir or pilgrimage place appears in a district question. Read the number on the accompanying current-boundary map before memorising a headquarters. A town name on a pre-2022 map can remain correct geographically but lead to the wrong present-district option.

Exam anchor: Nagarjuna Sagar's AP-side regional impact, limestone-cement activity and Palnadu historical traditions are separate recall cues. This is a place-to-theme association, not a claim that every landmark in the surrounding region belongs inside the district. Keep a separate column for a river or landscape, a site or activity, and the administrative headquarters. In a map question, begin at the state outline, narrow to the regional belt, and only then select the district polygon. The order is more dependable than recognising a familiar town name in isolation.

Boundary and date caution: Narasaraopeta is the headquarters. A pre-2022 Guntur record may cover the same place without using the district name Palnadu. District-level population, area, output and mandal totals are especially sensitive to reorganisation. An exact figure should carry its reference year and boundary vintage; this book does not silently attach an old census total to a new polygon. If the stem quotes an older notification, answer for that date. If it asks for the current district, use the 2026 map and official district portal.

Worked example: Palnadu is an inland central district with headquarters at Narasaraopet. Nagarjunakonda or a Krishna reservoir clue may lead students to the broader region, but a map dot should not replace current administrative verification. An old Guntur district source may cover Palnadu areas. For an exam, pair the present district, headquarters and one physical or heritage anchor without borrowing historical totals.

Active recall: Name the headquarters of Palnadu; place it on the map; give one physical-geography anchor and explain the dated boundary trap above.
