The Mayor Helpline -- 9643096430 -- however, is not a toll-free facility and will attract local telephone charges.
"Citizens can call on this number or send text messages or photographs on Whatsapp regarding any situation on sanitation or corruption-related issues," Gupta told reporters after being elected as Mayor.
The officials will have to respond to the complainants received through the helpline "within 24 hours", he said.
North Delhi Municipal Corporation (NDMC) has six Zones -- City, Rohini, Narela, Sadar Paharganj, Karol Bagh and Civil Lines.
The helpline would function from 9 AM to 5 PM on weekdays, but citizens can post complaints otherwise, using text messages or through internet messaging application Whatsapp during weekends and other holidays.
"We have connected the phone line with an answering machine and complaints would also get recorded during absence of our staff beyond working hours, through it," Gupta added.
