However, applications for fresh Permanent Account Number (PAN) will continue during this time on the two designated and government-authorised web portals of NSDL and UTIITSL.
"The Income Tax department is in the process of upgrading software applications. It is for information of PAN applicants that PAN allotment by the department will remain suspended between October 5-9 due to PAN data migration activity.
"However, PAN applications, through online and offline modes, will continue to be received by PAN service centres of M/s NSDL and M/s UTIITSL," an official statement said.
"The backlog of PAN applications will be cleared within three days. Inconvenience to taxpayers is regretted," the statement said.
PAN is a 10-digit unique alpha-numeric number allotted by the I-T department to individuals and entities for tax purposes.
