The United States remains one of the most fax-active countries in the world. Healthcare, legal, government, real estate, and financial industries all rely on fax as a standard document exchange channel. If you need to send a signed form, insurance document, tax filing, or legal contract to a US recipient, this guide covers everything you need to know.
US fax number format
US fax numbers follow the North American Numbering Plan (NANP), the same system used for voice calls:
- Country code: +1
- Area code: 3 digits (e.g. 212 for New York, 213 for Los Angeles, 312 for Chicago)
- Local number: 7 digits
- Full format: +1 (212) 555-0100
When sending from an online fax service, select United States (+1) from the country dropdown, then enter the 10-digit number (area code + local number) without any leading digits.
Industries that use fax in the US
Healthcare
The US healthcare system is one of the largest fax users globally. HIPAA (Health Insurance Portability and Accountability Act) designates fax as a recognised secure channel for transmitting protected health information (PHI). Common uses include:
- Sending referral letters between physicians and specialist offices
- Submitting prior authorization requests to insurance companies
- Exchanging lab results and radiology reports between facilities
- Patient records requests and medical record transfers
Most major hospital networks, insurance providers such as Aetna, UnitedHealth, Cigna, and Blue Cross Blue Shield, and independent clinics still maintain active fax lines for these workflows.
Legal and real estate
Law firms, title companies, and real estate agents routinely fax:
- Signed contracts and purchase agreements
- Court filings and legal notices
- Property disclosure forms and escrow instructions
- Powers of attorney and notarized documents
In many US jurisdictions, fax is explicitly recognised as a valid method of service, meaning a faxed document carries the same legal weight as a mailed original.
Government and tax
The IRS (Internal Revenue Service) maintains fax numbers for specific submission categories, including amended returns, responses to audit notices, and certain identity verification requests. State tax agencies and social service offices similarly accept faxed submissions for forms, appeals, and benefit applications.
Other federal and state agencies — the Department of Veterans Affairs, Social Security Administration, state licensing boards — also use fax for document submission.
Financial services
Banks, credit unions, and mortgage lenders use fax to exchange signed authorizations, wire transfer instructions, loan applications, and identity verification documents. Fax is preferred over email for these communications because it does not pass through third-party mail servers.

FAQ
Do I need a US phone number to send a fax to the US?
No. You only need the recipient's US fax number. You do not need your own number.
Can I fax to the IRS?
Yes. Enter the IRS fax number for the specific notice or form type. IRS fax numbers vary by form and processing center — always use the number printed on the IRS notice you received or published on irs.gov for the specific form category.
How long does it take for a fax to reach a US number?
Most US fax deliveries complete within 2–5 minutes. Heavily trafficked lines (IRS, large insurers) can be busy during peak hours; the service retries automatically.
Is there a size limit for faxing to the US?
We support PDFs up to 50 pages. For very large documents, split the file if needed.
Are documents deleted after sending?
Yes. Your uploaded file is deleted from our servers after the fax is delivered. We do not archive or store your documents.
