Hey!
Provisional certificateis granted to students on behalf of theoriginal certificatewho passes the University or Board Examination, and it certifies that you haveundergone the education mentioned in the certificate. For most universities, the actual certificates areissued after a convocation.

This also means that this is atransitional certificateuntil the actual certificate is issued. The provisional certificate is also accepted by thecompanies who are recruiting or the universities who are accepting a postgraduate candidature.

Once the degree is issued by the concerned university or college, theprovisional degree becomes invalid.Before that, there is no expiry date.

Hope this will help you!
