Wal-Mart Stores, Inc.: NPI records, locations and last-update dates
The CMS NPPES file for September 2026 has 823 active organization (NPI-2) records under the legal name WAL-MART STORES, INC., at 819 distinct practice addresses in 40 states. 26.9% of them show an NPPES last-update date more than five years old.
NPPES counts each legal name separately. Other legal names among the 500 with the most practice-location rows contain “Walmart”: Wal-Mart Stores East LP (4,751 records, ranked 2nd), Walmart Inc. (1,390 records, ranked 5th), Wal-Mart Stores Texas LLC (683 records, ranked 22nd) and Wal-Mart Stores Texas, LP (210 records, ranked 147th). NPPES does not record whether these names belong to one company, so this profile counts only records under Wal-Mart Stores, Inc.

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 (124); the ten largest cities are listed under the table.
A practice address can carry more than one NPI-2 record: 4 addresses here have two or more records (8 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 828 other-name entries on 810 of these 823 records, 814 different names in all; 812 of those names appear on only one record. Names on more than one record: Wal-Mart Pharmacy (4 records); WAL-MART PHARMACY (2 records).
When the records were last updated
26.9% of Wal-Mart Stores, 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 64.9% for the 17,115 active NPI-2 records whose primary taxonomy is Eyewear Supplier, this organization's most common; among this organization's own 713 records with that code, the share is 16.8%. Our NPI Staleness Report explains the measure. The oldest last-update date on these records is from 2007; 15.9% were never updated after the NPI was issued.
| Time since last update | Records | Share |
|---|---|---|
| Under 1 year | 4 | 0.5% |
| 1 to 3 years | 574 | 69.7% |
| 3 to 5 years | 24 | 2.9% |
| 5 to 10 years | 25 | 3.0% |
| 10 years or more | 196 | 23.8% |
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.
| Weekly file | Profile records re-issued | With a newer update date | New NPIs under this name | Fields changed |
|---|---|---|---|---|
| 2026-09-07 to 2026-09-13 | 0 | 0 | 0 | none |
| 2026-09-14 to 2026-09-20 | 0 | 0 | 0 | none |
| 2026-09-21 to 2026-09-27 | 0 | 0 | 0 | none |
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, sha2566573e0d148c18a9a9d974248d77447744bd9666aa288c38d13ebf3d766e3cec4, 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 STORES 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 11th. 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.
