In NEET (National Eligibility cum Entrance Test) registration, you typically need to provide a caste certificate that is recognized by the state or central government, depending on the category you are applying under. For Andhra Pradesh or other states, the following general guidelines apply:

1. Central OBC Caste Certificate: If you have a Central OBC (Other Backward Class) certificate, it is generally accepted for NEET registration and admission processes. Central OBC certificates are recognized across India.

2. State-Specific Requirements: While a Central OBC certificate is broadly accepted, some state-specific quotas or benefits may require a local or state-issued caste certificate. This is particularly relevant for state quota seats or specific state-based scholarships.

3. Verification: Ensure that the Central OBC certificate meets the criteria specified in the NEET information bulletin and the guidelines of the state of Andhra Pradesh. If there are state-specific requirements, you may need to comply with those as well.
