What 423 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 423 was registered in Karachi West 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. 3 selects the district inside that division, which gives us Karachi West. The two digits that follow — positions four and five — narrow it further to a local registration zone inside the district.
TEHSILS OF KARACHI WEST
Karachi West 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 | Orangi | Karachi West | Sindh |

COMMON QUESTIONS
Which district is CNIC code 423?
423 belongs to Karachi West District in Sindh, within Karachi Division.
Digit 1 (4) is the province, digit 2 (2) the division, and digit 3 (3) the district within that division.
Does a 423 CNIC mean the holder lives in Karachi West?
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 West District?
Karachi West District covers 4 administrative tehsils: Orangi, SITE, Manghopir, Kemari.
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.
What comes after 423 in a full CNIC?
A complete CNIC is thirteen digits: the five-digit regional prefix, then a seven-digit family/serial number, then a single check digit that also encodes gender (odd for male, even for female).
For Karachi West, this register documents 1 local-zone code: 42301.
How reliable is the code 423?
423 is a documented anchor code — it appears consistently in public records and published examples, so the district mapping is solid.
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.
