You cannot apply for an equivalency certificate using only the acknowledgement number of your migration certificate application .
The equivalency certificate process generally requires you to upload or submit actual certificates-such as your 10th, 12th, and migration certificate copies-not just proof that you have applied for them (https://www.vhseportal.kerala.gov.in/public/ec/instructions) (http://www.dhsekerala.gov.in/downloads/circulars/0109110702_forms.pdf) .
The acknowledgement number is only a receipt showing you have requested a migration certificate, not the certificate itself (http://www.dhsekerala.gov.in/downloads/circulars/0109110702_forms.pdf) .
Most official instructions clearly state: Upload the actual migration certificate (not just acknowledgement) along with other required documents for equivalency (https://www.vhseportal.kerala.gov.in/public/ec/instructions) (http://www.dhsekerala.gov.in/downloads/circulars/0109110702_forms.pdf) .
Wait to receive your migration certificate .
Once you have the migration certificate, upload it (scan or photocopy) along with other necessary documents for your equivalency certificate application (https://www.vhseportal.kerala.gov.in/public/ec/instructions) (http://www.dhsekerala.gov.in/downloads/circulars/0109110702_forms.pdf) .
In summary: You need the actual migration certificate, not just the acknowledgement number, to apply for an equivalency certificate.
If you urgently need to proceed, contact the relevant board or university office to ask if they will temporarily accept the acknowledgement as proof, but as per standard rules, it is not accepted.
