NIH Fax Number — Clinical Center, Grants, and Records Submissions

The National Institutes of Health is made up of many institutes and centers, plus the NIH Clinical Center and central offices for grants and records, so faxes are routed by the specific program rather than to one agency number. A patient-referral document for the NIH Clinical Center goes to the office named in the referral instructions, while grant-related paperwork and FOIA requests each have their own contacts. The dependable path is to open the official page for the exact NIH institute, center, or program you are working with, which lists the accepted contact methods for that submission. Confirm whether fax, email, or an online system is expected before you send, since NIH commonly directs submissions through electronic portals.

What You Can Fax to National Institutes of Health (NIH)

  • Patient-referral and medical documentation for the NIH Clinical Center where fax is indicated
  • Research-participant records requested by a study team
  • Grants-management correspondence a specific NIH institute has asked you to fax
  • FOIA requests and supporting materials
  • Program forms listed on an NIH institute or center page
Tip: Confirm the fax destination on the specific NIH institute or program page before sending, because a general NIH number will not reach the office you need. Fax is not universally required at NIH — many submissions go through eRA Commons, secure email, or study-specific portals — so check the accepted channel first. When a document includes personal health or research information, use a secure service and keep the transmission receipt as your record of the submission.

Faxing to National Institutes of Health (NIH) — FAQ

No. NIH comprises many institutes, centers, and offices, each managing its own correspondence, so there is no agency-wide fax line. Identify the specific institute, center, or program involved and use the contact information published on its official page.

The NIH Clinical Center accepts referrals through study-specific and central intake processes described in the referral instructions for the relevant protocol. Confirm the accepted channel and destination in those instructions, and label documents with the patient and protocol identifiers requested.

Most NIH grants activity runs through eRA Commons and the electronic submission systems named in the funding announcement, not by fax. Check the specific institute's grants-management instructions and use the electronic channel unless the office has explicitly asked you to fax a document.

NIH's FOIA office lists its accepted submission methods, which typically include an online portal, email, and mail. Review the current NIH FOIA page to confirm whether fax is accepted and to obtain the correct destination before submitting.
