In India, online company registration usually takes around 10-15 days to complete. The process involves obtaining a Digital Signature Certificate (DSC) and Director Identification Number (DIN), filing the required documents, and obtaining the Certificate of Incorporation from the Registrar of Companies (ROC). The time taken can be reduced by ensuring that all required documents are complete, accurate, and submitted in the proper format. Expedited registration services are also available for an additional fee.
