Punjab National Bank (PNB), founded in 1894, has its headquarters in New Delhi. PNB was nationalized in 1969 along with 13 other major banks and remains one of India's largest public sector banks. While it has branches across India including Chandigarh and operates internationally, its corporate headquarters (registered office) is in Delhi. Note: The question appears incomplete, likely asking 'Where is Punjab National Bank headquartered?'
