The NPI application is free and takes about 20 minutes to complete. When applications are submitted via email, NPIs arrive within 1-5 business days. Mailed applications are processed within 20 days, and returned by U.S. mail. Many payers will ask for you to submit NPIs in conjunction with existing identification numbers already in use, so they can get the new numbers into their systems.
