The SSP portal is a platform for students to apply for scholarships. The term "counselling number" is not clearly defined in the search results, but it seems to be related to the admission or counselling process for scholarships. Here are some relevant points from the search results:

• The SSP helpline number is 080-35254757, which can be called for any clarifications or problems during application submission.
• Aadhaar is mandatory to apply for scholarships through SSP. Students who do not have an Aadhaar number should submit their 11-digit Aadhaar Enrollment ID.
