The issue about messages received from banks and mobile service providers was raised by senior lawyer K V Vishwanathan, who was representing one of the petitioners.
Vishwanathan told the bench, which also comprised Justice Ashok Bhushan, that the people were "in a panicky situation" as the messages received from the banks and telecom service providers were threatening them of deactivation of accounts or mobile numbers if they failed to link them with Aadhaar.
"I do not want to say this in the presence of media people, but I am also receiving such messages," Justice Sikri said.
During the hearing, Vishwanathan said the Centre should tell the banks and mobile service providers not to send such messages but they should instead inform the customers about the last date of linking Aadhaar.

The apex court later made it clear that banks and telecom service providers will have to indicate the last date of linking the accounts and mobile numbers with Aadhaar in their communications with the customers.
The bench also observed that the petitioners could raise all issues before another bench which would commence the final hearing on Aadhaar-related matters in the last week of this month.
The recent affidavit filed by the Centre in the top court in Aadhaar matter was also referred to during the hearing.
Regarding linking of bank accounts with Aadhaar, the Centre has said in its affidavit that though the last date was December 31, it may be extended up to March 31 next year.
On mobile number linking, it said since the apex court's February 6 this year order required Aadhaar-based e-KYC verification of subscribers within one year, the February 6, 2018 deadline for this cannot be modified by the government unilaterally.
