Nigeria NIN Slip & e-ID OCR Python SDK
Instantly extract data and MRZ from Nigerian IDs using our native Python library.

Parsing NIN Slip Challenges
Parsing NIN Slips presents unique challenges. Firstly, the print quality on some slips can be inconsistent, leading to blurred or distorted characters. Secondly, variations in layout and design across different NIN Slip versions can complicate accurate data extraction.
Why StructOCR for Nigeria
StructOCR's model is specifically trained on a vast dataset of Nigerian NIN Slips and e-ID cards, enabling robust and accurate data extraction even with variations in print quality and layout. Our Python SDK simplifies integration into your existing systems, providing a clean and intuitive id parsing api for seamless document processing. It also fully supports parsing the Machine Readable Zone (MRZ) for secondary validation.
Common Use Cases in Nigeria
- Digital Onboarding: Verify users for Fintech apps in Nigeria.
- Telecom Registration: Automate SIM card registration with NIN Slip.
- Hotel Check-in: Speed up guest registration workflows using MRZ scans.

}Frequently Asked Questions
Does the Python SDK handle image uploads?
Yes, the SDK automatically handles base64 encoding and file uploads.
Does the API extract MRZ from Nigerian IDs?
Yes, if the uploaded image is a Nigerian e-ID card, the API automatically parses and returns the MRZ lines inside the `additional_fields` object.
Is data stored?
No. Images are processed in-memory and deleted immediately.
How to handle errors?
The SDK result dictionary contains a 'success' boolean and an 'error' message if failed.
