Walmart Pharmacy Fax Number — Send a Prescription to the Right Store

Walmart pharmacies operate inside individual supercenters and neighborhood markets, and each in-store pharmacy has its own fax line rather than a shared national number. Prescribers usually e-prescribe, but paper prescriptions, refill authorizations, and prior authorization forms still come by fax to the specific store. The store's pharmacy fax is tied to that location's phone number and is easiest to confirm by calling the pharmacy counter directly. Walmart also runs a separate mail-order and home-delivery pharmacy, which uses its own intake process distinct from any single store's fax.

What You Can Fax to Walmart Pharmacy

  • Paper prescriptions from a clinic
  • Refill authorization forms
  • Prior authorization documentation
  • Prescription transfer requests
  • Insurance or discount-program updates
Tip: Confirm whether the prescription is going to an in-store Walmart pharmacy or to Walmart's mail-order service, because they are separate intake paths with separate numbers. Prescription faxes contain protected health information, so a HIPAA-eligible service such as Send FAX Mail's Business plan ($79.99/month) keeps the send compliant and gives you a delivery receipt. Repeat the patient's name and date of birth on the prescription page.
