Question 1

Who are the top ABA NPI / taxonomy support firms in the United States?

Accepted Answer

ABA Rank lists 17 ranked ABA NPI / taxonomy support firms serving providers across the United States. The order on this page is the current public ranking - recomputed nightly from the same disclosed 100-point Index used across the rest of the directory (qualified public reviews, profile completeness, verification recency, and primary-category fit), with no paid tier among the inputs. The leader at the top of the page is the current #1 in NPI / Taxonomy Support for the United States as of the last refresh.

Question 2

How does ABA Rank rank NPI / taxonomy support firms in the United States?

Accepted Answer

Every firm on this page is scored on the same 100-point Index used across ABA Rank: 50 points from qualified public reviews, 30 points from profile completeness, 15 points from verification recency, and 5 points from primary-category fit. Location does not change the score - it only changes who appears in the slate. Methodology is fully disclosed at /how-we-rank; there is no sponsored placement and no paid ranking boost inside the ranked list.

Question 3

How many ABA NPI / taxonomy support firms serve the United States?

Accepted Answer

17 ABA NPI / taxonomy support firms are currently ranked for the United States on ABA Rank. The count reflects vendors that operate nationally or accept clients across multiple states. New firms are added through editorial seed batches and the public submission flow at /suggest-vendor.

Question 4

Are these ABA NPI / taxonomy support firms in the United States verified?

Accepted Answer

Verified firms on ABA Rank have claimed their profile from a work email at the company domain and completed the credential or business-registration check disclosed in the methodology. Verified firms carry a seal and a fresh verification date, which feeds an operational Index signal any free listing can earn; unverified firms remain ranked but are clearly marked. Verification is not a paid ranking boost. Verification status appears on every card on this page so a reader can shortlist by trust signal as well as by Index score.

Question 5

Does ABA Rank charge NPI / taxonomy support firms to be listed in the United States?

Accepted Answer

No. The ranked list is editorial. Any eligible firm can be listed for free, and there is no paid placement or pay-for-rank inside the ranked slate. Optional paid tiers (Verified at $490/yr and Sponsor at $1,490/yr) are disclosed on every profile and on /how-we-rank - as of methodology v3.0 subscription tier is not a term in the Index, so buying or dropping one does not move a firm within this list. Sponsored slots are visibly labeled and render above the ranked list rather than inside it.

Question 6

How often is the NPI / Taxonomy Support ranking for the United States updated?

Accepted Answer

Rankings recompute nightly. New disclosed inputs (profile edits, verifications, qualified review submissions) propagate into the next refresh, so a firm that improves its disclosed inputs can move up between visits. The page itself is server-rendered with a 6-hour ISR window, so AI crawlers and search engines see fresh ordering without re-querying on every request.
