What 42501 tells you
A Pakistani CNIC is thirteen digits long, and the first five of them are not random. They are a location record, written at the moment the card was registered. A card whose number opens with 42501 was registered in Karachi Malir District, Sindh, in Karachi Division.
Reading it left to right: 4 is the province digit and is definitive — 4 always means Sindh. 2 selects the division inside that province, here Karachi Division. 5 selects the district inside that division, which gives us Karachi Malir. The final pair, 01, is a local registration zone — roughly union-council level, recorded in this register as Karachi Malir — Malir / Bin Qasim belt.
TEHSILS OF KARACHI MALIR
Karachi Malir District is divided into 4 administrative tehsils. NADRA’s internal registration zones do not map one-to-one onto tehsil boundaries, so treat this as the administrative picture rather than a decoder for digits four and five.

| 1 | Malir | Karachi Malir | Sindh |

COMMON QUESTIONS
Which district is CNIC code 42501?
42501 belongs to Karachi Malir District in Sindh, within Karachi Division.
The first three digits (425) identify the district; the last two (01) identify a local registration zone inside it — recorded here as Karachi Malir — Malir / Bin Qasim belt.
Does a 42501 CNIC mean the holder lives in Karachi Malir?
No. The regional prefix records where the card was registered with NADRA, not where the holder lives now. People who move, or who register at a family address, keep the original prefix.
It is also not proof of domicile. Domicile is a separate certificate issued by the district administration.
Which tehsils fall under Karachi Malir District?
Karachi Malir District covers 4 administrative tehsils: Malir, Bin Qasim, Gadap, Ibrahim Hyderi.
Tehsil boundaries and NADRA's internal registration zones are not the same thing, so the last two digits of a CNIC do not map one-to-one onto this list.
How reliable is the code 42501?
42501 is reconstructed from the standard coding scheme and community lists rather than an official published table. The province digit is definitive; the district mapping should be treated as a strong indication rather than a guarantee.
NADRA has never released a complete district-to-prefix table, which is why this register marks every entry as either a documented anchor or a derived code.
