Germany is one of the US's largest trading partners, and faxing remains a surprisingly common channel for legal, healthcare, and government correspondence there. If you need to fax to Germany from the US, getting the number format right is everything — one misplaced zero and the transmission fails without explanation.
This guide covers the complete +49 country code format, every major city's area code, what it costs, GDPR considerations for sensitive documents, and a step-by-step walkthrough using an online fax service.
Germany Fax Number Format: The One Rule You Must Know
Germany's country code is +49. The critical rule: drop the leading zero from the German area code when dialing internationally.
German fax and phone numbers are written domestically with a trunk prefix of 0 — for example, Berlin's area code is written as 030. Internationally, that zero is dropped and replaced by the country code. So 030 1234567 in Berlin becomes +49 30 1234567 from the US.
The format from any online fax service:
+49 [area code without leading 0] [local number]
The format from a physical US fax machine:
011-49-[area code without 0]-[local number]
Quick example: A Munich law firm's fax number printed on their letterhead as 089 987 6543 should be entered as +49 89 987 6543 (or dialed as 011-49-89-9876543 from a traditional machine).
Major City Area Codes
| City | Domestic Format | International Format |
|---|---|---|
| Berlin | 030-XXXXXXX | +49 30 XXXXXXX |
| Munich | 089-XXXXXXX | +49 89 XXXXXXX |
| Hamburg | 040-XXXXXXX | +49 40 XXXXXXX |
| Frankfurt | 069-XXXXXXX | +49 69 XXXXXXX |
| Cologne | 0221-XXXXXX | +49 221 XXXXXX |
| Stuttgart | 0711-XXXXXX | +49 711 XXXXXX |
| Düsseldorf | 0211-XXXXXX | +49 211 XXXXXX |
| Leipzig | 0341-XXXXXX | +49 341 XXXXXX |
| Nuremberg | 0911-XXXXXX | +49 911 XXXXXX |
| Bremen | 0421-XXXXXX | +49 421 XXXXXX |
Variable Area Code Lengths
German area codes range from 2 to 5 digits, with longer area codes used in smaller cities and rural regions. The total length of area code plus local number always falls between 9 and 13 digits (excluding the country code). If a number looks too short or too long, double-check with the sender — German numbers vary more than US ones.
How to Fax to Germany: Step-by-Step
The fastest and most reliable method is an online fax service like mFax.to. No hardware, no trip to a store — upload your document, enter the number, done.
Prepare your document
Export your file as a PDF. Germany uses A4 paper (210 × 297mm), which is slightly taller than US Letter (8.5 × 11in). If you can, format your document in A4 — most online services handle the scaling automatically, but an A4-formatted document displays cleanly on the recipient's printer without any rescaling artifacts.
Open mFax.to or your chosen service
Visit mFax.to from your phone or browser. No account is needed for a one-time send. If you fax Germany regularly, the mFax mobile app speeds up the process.
Enter the German fax number in +49 format
Type the number beginning with +49, followed by the area code (without the leading 0) and the local number. Most online services accept +49 30 1234567 directly — you do not need the 011 prefix that physical fax machines require.
Upload your document and attach a cover sheet
Attach your PDF and include a fax cover sheet. German business communication is formal — a cover sheet with sender name, sender fax number, recipient name, recipient fax number, and total page count is expected for professional correspondence. It also ensures the fax is routed to the right person without the recipient needing to read the enclosed pages.
Send and confirm delivery
Click Send. A reliable service provides a delivery confirmation receipt. For contracts or legal filings, follow up with a brief email to verify the fax was received and is legible on the recipient's end.
Physical Fax Machine Tips
If you're sending from a traditional fax machine over a landline or VoIP line, insert a brief pause (usually a comma in the dial string) after 011 before continuing with 49. For VoIP lines specifically, reduce the baud rate to 9,600 bps and enable T.38 protocol if available — standard voice-optimized VoIP compression causes significant fax errors on international transmissions.
What Does It Cost to Fax Germany From the US?
International fax rates vary widely between online services and retail locations. Here's a realistic comparison for a 5-page fax to Germany.
| Method | Cost per Page (Germany) | 5-Page Fax Total | Notes |
|---|---|---|---|
| mFax.to | ~$0.15–$0.30 | ~$0.75–$1.50 | International add-on; confirm at checkout |
| Fax.Plus | Varies by plan | Plan-dependent | Check Germany in destination rate table |
| OneTimeFax | $5 flat | $5 (up to 100 pages) | No account required; one-time pay |
| eFax | Per-minute surcharge | Varies | Better value for high-volume enterprise users |
| UPS Store | ~$3.00–$5.00/page | ~$15–$25 | Plus travel time and cover sheet fees |
| FedEx Office | ~$3.00–$5.00/page | ~$15–$25 | International rates vary by location |
Online services are typically 10–20× cheaper than retail for a multi-page fax. For a 10-page contract, that gap can mean the difference between $3 and $50.

Time Zone: When to Fax Germany
Germany observes Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) during daylight saving time (late March through late October).
| Your Time Zone | Germany CET (Winter) | Germany CEST (Summer) |
|---|---|---|
| Eastern (EST/EDT) | +6 hours | +6 hours |
| Central (CST/CDT) | +7 hours | +7 hours |
| Mountain (MST/MDT) | +8 hours | +8 hours |
| Pacific (PST/PDT) | +9 hours | +9 hours |
Note: The US and Germany switch to/from daylight saving time on different calendar dates each spring and fall, creating a brief 1-week window each year where the offset shifts by an hour. If you're faxing during late March or early November, double-check the current difference.
German business hours are roughly 8am–6pm CET/CEST, Monday through Friday. To reach a German office during business hours, send from the US:
- From Eastern Time: between 2am–12pm ET
- From Pacific Time: between 11pm–9am PT
For non-urgent faxes, timing is less critical — German offices typically receive faxes 24/7.
GDPR and Faxing to Germany: What You Need to Know
Germany enforces the EU's General Data Protection Regulation (GDPR) strictly, and Germany's own state data protection authorities have been among the most active in Europe. If your fax contains personal data — names, medical information, HR records, financial details — you need to be aware of one important fact.
Traditional fax is not GDPR-compliant for personal data. The Bremen Data Protection Authority (LfDI Bremen) has explicitly stated that fax is not a safe method for transmitting personal or sensitive information. Reasons include:
- Transmissions are unencrypted and can be intercepted on telephone networks
- Physical fax machines leave documents in an unsecured output tray accessible to anyone in the office
- There is no reliable proof of who actually received the document
- Transmission logs can be altered
What this means in practice:
- For routine, non-personal business documents (order confirmations, technical drawings, schedules), standard fax is acceptable
- For documents containing personal data — patient records, employment files, personal contracts — use a GDPR-compliant encrypted fax service that provides audit logging and transmission encryption
- mFax Business is designed for organizations that need compliance-grade faxing, including encryption and delivery audit trails
GDPR Penalty Risk
GDPR violations can result in fines up to €20 million or 4% of annual global turnover. For healthcare providers, legal firms, and HR departments faxing personal data to Germany or any EU country, using an encrypted, GDPR-compliant fax service is not optional — it is a legal requirement.
Tips for Getting Your Germany Fax Delivered Successfully
Drop the zero — every time. The single most common mistake when faxing Germany is leaving the leading zero on the area code. 030 must become 30. This alone accounts for the majority of failed international transmissions.
Use A4 format where possible. Germany's standard paper size is A4. If you're sending from a PDF formatted for US Letter, most online services rescale automatically — but for legal or medical documents where formatting precision matters, format in A4 before sending.
Include a cover sheet. German professional culture values formality. A proper cover sheet with sender information, recipient information, date, and page count is expected — and it helps route the fax to the right person in large organizations. See our fax cover sheet guide.
Send during German business hours for urgent documents. If a response is needed same-day, send before 12pm Eastern Time (6pm CET). For non-urgent documents, German offices receive faxes around the clock.
Verify before sending sensitive data. Before faxing personal data to Germany, confirm that:
- The recipient's fax service is GDPR-compliant
- You are using an encrypted transmission service
- You have a legal basis for sharing the personal data (contract, consent, legal obligation)
Troubleshoot failed transmissions. If a fax to Germany fails repeatedly:
- Confirm the number format:
+49+ area code without leading0+ local number - Check that the receiving line accepts international calls
- If using a physical machine, lower baud rate to 9,600 bps and enable T.38 or Overseas Mode
- Try an online fax service — they use optimized international routing that bypasses VoIP compatibility issues entirely

How Germany Compares to Other International Fax Destinations
Germany is among the more straightforward European countries to fax — the number format is consistent, most German businesses maintain working fax lines for official correspondence, and international transmissions route reliably. Compare it to:
- United Kingdom (+44): Same drop-the-zero rule, similar business culture, but separate formatting conventions for different regions
- Japan (+81): Far heavier fax culture — over 90% of local governments still fax daily — with its own formatting rules and A4 considerations
- Mexico (+52): Closer time zones for US senders, different area code structure for mobile vs. landline numbers
