How long does it take to get an NPI number?

Answer: With SimpleNPI, usually within 10 minutes after the form is complete, delivered by email and text with all the documentation. Applying yourself at NPPES, CMS usually issues the number within a few business days, often within minutes when the Social Security match passes. If CMS holds an application for a manual name check it can take up to about 20 days.

Why most applications issue in minutes

NPPES checks the name, date of birth and Social Security number against Social Security records in real time. When they match exactly, the NPI is assigned automatically and emailed. That is why the legal name has to match the Social Security card, not a nickname or a married name that has not been updated.

What slows an application down

A name that does not match Social Security records (a recent marriage, a hyphen, a middle name used as a first name); a mailing address the postal database cannot verify; a taxonomy that needs a license number left blank; or an application filed after midnight Eastern, which issues around 6 am Eastern when the overnight batch runs. Applications CMS pulls for a manual review are handled by the NPI Enumerator and can take up to about 20 days.

After the NPI is issued

The number is usable immediately. It appears in the public NPI registry lookup the next day, because CMS refreshes the public file once a day. Payers and platforms that verify against the registry can see it then.
