Introduction
Overview of the Standard Framework
As part 286 of the GA/T 2000 series, this standard constructs a unique identification system for the handling of residence permits. The code adopts a 22-bit fixed-length digital structure to achieve accurate traceability of the entire acceptance process.
Coding structure analysis
| Field position | Length | Content description | Example |
|---|---|---|---|
| 1-9 digits | 9 | Police station code (referenced GA/T 2000.3) | 110105001 |
| 10-17 digits | 8 | Acceptance date (YYYYMMDD format) | 20230815 |
| 18-22 digits | 5 | The serial number is reset daily (starting from 00001) | 00342 |
Technology Evolution Analysis
Compared with the early regional self-coding method, this standard achieves three major breakthroughs:
- National uniformity: Solve the problem of cross-regional data exchange through standardization of police station codes
- Precise time dimension: Date fields support statistical analysis by time dimension
- Anti-duplicate mechanism: The serial number is reset daily to avoid the risk of duplicate numbers
Implementation Suggestions
Attention should be paid to the development of the Residence Permit Management System:
- The police station code library needs to be updated synchronously with the GA/T 2000.3 standard
- The transaction lock mechanism is required to ensure the uniqueness of the sequence number generation
- It is recommended to use the server system time for the date field to prevent tampering
Actual application case: After the system of a provincial public security bureau was transformed, the response time of residence permit business query was shortened from 15 seconds to 2 seconds.
Associated standard extension
The police station coding rules of GA/T 2000.3 need to be used in conjunction, and the code structure includes:
- 1st-2nd digit: provincial code
- 3rd-4th digit: city code
- 5th-6th digit: district and county code
- 7th-9th digit: police station serial number
