Walmart Inc.: NPI records, locations and last-update dates

Where the records are

Practice locations are distinct street-address and ZIP pairs across each record's primary practice address and its secondary practice locations. California has the most records (318); the ten largest cities are listed under the table.

A practice address can carry more than one NPI-2 record: 95 addresses here have two or more records (191 records in all). That is why the record count is higher than the location count.

Other names on file

NPPES lets each record list other names the organization uses or has used, such as a store or department name. The entries below are those names as filed; NPPES does not say why a name was added. NPPES lists 1,430 other-name entries on 1,113 of these 1,390 records, 1,057 different names in all; 1,055 of those names appear on only one record. Names on more than one record: Walmart pharmacy 10-3164 (59 records); Walmart Pharmacy 10-3129 (2 records).

When the records were last updated

1.1% of Walmart Inc.'s records have a last-update date before 1 Oct 2021, five or more years before the analysis date. In the same September 2026 file, the share is 58.8% for all 1,972,058 active NPI-2 records and 54.2% for the 63,681 active NPI-2 records whose primary taxonomy is Community/Retail Pharmacy, this organization's most common; among this organization's own 1,280 records with that code, the share is 0.7%. Our NPI Staleness Report explains the measure. The oldest last-update date on these records is from 2018; 4.8% were never updated after the NPI was issued.

The last-update date shows when the record was last changed in NPPES. It does not show whether the address or phone number is still correct, so the older a record's last update, the more an address or phone number is worth checking before use.

Change log

Tracked since the September 2026 NPPES file (records through 13 Sep 2026). NPPES publishes weekly update files between monthly releases; each re-issues every record that changed. This page compares those records with the monthly file.

The first weekly window overlaps the monthly cut, so its records match the monthly file. From the October file on, this log adds month-over-month additions, deactivations and address changes.

Sources and method

• Source: CMS NPPES Data Dissemination, full replacement monthly file V.2 for September 2026 (NPPES_Data_Dissemination_September_2026_V2.zip, sha256 6573e0d148c18a9a9d974248d77447744bd9666aa288c38d13ebf3d766e3cec4, records through 13 Sep 2026), plus the three weekly update files dated 7–27 Sep 2026.
• Taxonomy names: NUCC Health Care Provider Taxonomy code set 26.1. Primary taxonomy is the code flagged primary on the record (code 1 if none is flagged).
• Scope: active NPI-2 records whose legal business name, upper-cased with punctuation removed and spaces collapsed, equals “WALMART INC”. Deactivated NPIs are excluded; NPPES blanks their names, so they cannot be attributed to an organization.
• Locations: distinct pairs of normalized first address line and five-digit ZIP across primary and secondary practice addresses.
• Last-update age: years from each record's last-update date to 1 Oct 2026; “last NPPES update 5+ years ago” means a last-update date before 1 Oct 2021. The NPI Staleness Report explains the measure.
• Selection: we rank the 1,444,038 legal business names on active NPI-2 records by practice-location rows; this name ranks 5th. The rank counts legal names, not corporate families: a company that registers each store under one legal name ranks high, and a company that files under several legal names appears once for each.
