You can ask the bank to change the PAN in the challan within 7 days from the date of deposit of advance tax. In case, the period of 7 days has got expired, you can request your assessing officer by way of an application, attaching thereby a copy of challan, to change the PAN.

I dont find any. Most safe way is to approach assessing office with an application in duplicate and get the application acknowleged by ASK number and receipt in assessee's copy.
