Mobile vs Landline Numbers in the US
Unlike many countries, the United States does not have separate prefixes for mobile and landline numbers. Both use the same 10-digit format with area codes, making it impossible to tell if a number is mobile or landline just by looking at it.
📱 Mobile Numbers
Format: +1 (XXX) XXX-XXXX
Can have any area code, including numbers that moved from other areas (number portability)
☎️ Landline Numbers
Format: +1 (XXX) XXX-XXXX
Typically tied to geographic location, but format is identical to mobile
North American Numbering Plan (NANP)
The +1 country code is shared by 26 countries and territories in the North American Numbering Plan (NANP). This means these countries all use the same dialing format:

Common Mistakes When Calling the US
❌ Forgetting the Exit Code
Always dial your country's exit code (usually 00) or use + before dialing 1
❌ Skipping the Country Code
You must dial "1" after the exit code, even though the US shares +1 with Canada
❌ Missing the Area Code
US numbers ALWAYS require the 3-digit area code - never skip it
❌ Dialing "1" Twice
From Canada, don't dial 011 + 1. Within NANP, just dial 1 + area code + number

US Toll-Free & Special Numbers
The US has several special number prefixes for toll-free and premium services. These numbers use the +1 country code but have reserved area codes:
| Prefix | Type | Notes |
|---|---|---|
| 800 | Toll-Free | Original toll-free prefix, free to call from US |
| 888, 877, 866, 855, 844, 833 | Toll-Free | Additional toll-free prefixes (same as 800) |
| 900 | Premium Rate | Pay-per-call services, higher charges apply |
| 911 | Emergency | Police, fire, ambulance — works from any phone |
| 411 | Directory | Directory assistance (may incur charges) |
⚠️ International Callers: US toll-free numbers (800, 888, etc.) are NOT free when calling from abroad. You will be charged international rates. To call a US 800 number from overseas, dial +1-800-XXX-XXXX.
Troubleshooting: Why Is My Call to the US Not Going Through?
1. Missing the +1 Country Code
Always dial +1 (or your exit code + 1) before the US number. Without it, the call won't route to the United States.
2. Missing the Area Code
Unlike some countries, US numbers ALWAYS need the 3-digit area code. You cannot skip it, even if calling from within the same state.
3. Dialing "1" Twice from Canada
From Canada, just dial 1 + area code + number. Do NOT dial 011 + 1 (that adds an extra "1" and the call will fail).
4. Calling a Toll-Free Number from Abroad
Some US 800/888 numbers block international callers. If the call doesn't connect, try the company's local number instead.
5. Spam Filtering by US Carriers
US carriers aggressively filter international calls as spam. If calls are being dropped, use BubblyPhone which routes through verified US numbers for better connection rates.
