HOW TO SEARCH PTEC NUMBER BY HAVING ONLY PAN ?

Hi,

She has started new business activity of dealing in food grains and pulses.

Her husband informed me about to get register for PTEC.

She has given to me PAN Card + Adhar Card Copy.

While I entered her PAN in PTEC Payment option, her name appeared perfectly.

Is it possible to know her PTEC Numbere ?

I request you to help me in this matter.

Thanks
