Dear Aspirant,

This happens when the information required innany of the place is not given or null or incorrect. Hence refresh and open it again via other device or browser and restart the process. Check for proper data entry, caps, internet connection.

The number comes to be invalid due to reasons like improper maintenance, receiveinv large number of calls. Hence at a moment it might not be available but can try later.

If it still shows the same status, you can contact the Helplines or write them a mail.

Hope this helps.

Good luck.
