The BISP 8171 Guide explains how the Benazir Income Support Programme (BISP) uses the 8171 system to help people check their eligibility and payment status quickly and conveniently. BISP is a federal social safety initiative in Pakistan that provides financial assistance (such as quarterly stipends) to low-income and vulnerable families, especially women heads of households, based on socio-economic data verified through the National Socio-Economic Registry (NSER). To use the 8171 system, beneficiaries can either visit the official 8171 web portal and enter their 13-digit CNIC (Computerized National Identity Card) number along with a captcha code to see if they qualify for support and when payments are due, or they can send their CNIC number via SMS to 8171 and receive a reply confirming their eligibility and payment details within minutes.
