PlainrosterSign inNPI lookup
Find the 10-digit ID for a person or a clinic, or see the name and address attached to a number you already have.
File: NPPES weekly file, week of 14–20 September 2026. Lookups read the NPPES Registry API. Plainroster is not CMS.
How to look up an NPI
- Enter the 10-digit number if you have it.
- Otherwise enter the person or the clinic. Add a city under More options when the name is common.
- Open the row and read the type, the taxonomy, and the practice address.
- Check the state license and the exclusion list next. The NPI result does not settle either one.
How to read a result
NPI 1679576722 is David A Wiebe, M.D., a Type 1 record in Orthopaedic Surgery, with a practice address in Kearney, Nebraska. Active means NPPES still enumerates that number. It does not say the Nebraska license is in force. The record lists Nebraska license 12637 so you can take that number to the state board. Plainroster does not publish a Nebraska license file.
State licenses are a separate check. Exclusion lists are a separate check.
What is an NPI?
An NPI is the 10-digit National Provider Identifier in the public NPPES file. CMS issues it to a person or an organization that bills health plans. The number identifies that record. It is not permission to practice, and it is not a statement that a board has approved the provider. This search reads the NPPES Registry API, which serves the same public file as the weekly download. Plainroster does not copy every NPI in the country into its own database.
Type 1 vs Type 2?
Type 1 is a person, such as a physician, a nurse, or another individual clinician. Type 2 is an organization, such as a clinic, a group practice, or a hospital. They are different numbers. A physician can hold a Type 1 NPI and also bill under a group’s Type 2 NPI. A name search usually returns the person. An organization name returns the clinic. Open the row and read the type before you copy the number onto a roster or a claim form.
How do I find a provider’s NPI?
Use the 10 digits when a claim, a directory, or the provider already gave them to you. That is an exact match. If you only have a name, search the person or the clinic. Open More options and add a city when several people share the last name. The city only narrows this search. It does not create a separate city page. When two rows come back, compare the practice address and the taxonomy, then keep the NPI on the row you meant.
What does deactivated mean?
Deactivated means NPPES no longer lists that number as an active enumeration. CMS or the provider has taken it out of active status. The badge describes the NPI file only. It does not say whether a state license is current, expired, or under an order. A license can lapse while the NPI stays active, and the reverse happens too. Read the NPI status here, then check the state license and the exclusion lists as their own questions.
How is an NPI different from a license?
A state license is permission from a medical board to practice. An NPI is an identification number in a federal file. Someone can have an active NPI and an expired license, or a current license and a deactivated NPI. California and Texas license checks on this site answer the board-file question. The exclusion search answers whether that NPI is on the OIG list or the SAM public extract. Use the three together when you add a person to a roster. A green NPI badge is not a board clearance.
