Dialing Format
To call a landline number in Sardhana from within India, subscribers must dial the trunk prefix '0', followed by the area code '1237', and then the local subscriber number. The local subscriber number typically consists of 6 digits, making the complete national significant number (NSN) 10 digits (0-1237-XXXXXX). For example, a local number might be 1237-456789.
