IMPORTANT RULES

US Dialing Rules and Format Requirements

Understanding these key rules will help you avoid common calling issues.

Always use +1 for international calls

From Senegal, you must include the +1 country code. This applies to all US calls, whether landline or mobile.

Use the area code

The area code (3 digits) is mandatory and identifies the region. You cannot reach a US number without the correct area code.

10-digit format is standard

All US phone numbers follow the format [area code] [exchange] [subscriber number], totaling 10 digits after the country code.

Leading zeros not needed

Do not add extra zeros before the area code. The +1 country code is all that is required to indicate an international call.

Toll-free numbers may have restrictions

Some special numbers (1-800, 1-888) may not work from international lines. If a toll-free call fails, contact the business for an alternative number.

Calling tips

Call during business hours in the US region where your contact is located. US business hours are typically 9 AM to 5 PM local time.
Check if your contact is in Eastern, Central, Mountain, or Pacific time. The US spans four major time zones.
Plan calls for early morning (Dakar time) to reach the US West Coast during their afternoon.
Avoid calling between midnight and 6 AM Dakar time, as it will be evening or night on the US East Coast.
Be aware that US observes daylight saving time from mid-March to early November; the time difference shifts by one hour during these transitions.

Business etiquette

Always confirm the time zone before scheduling. Misalignment can lead to missed calls.
For important calls, send a message first to confirm availability across time zones.
Keep conversations brief if calling across many time zones; both parties may face inconvenient hours.
In Senegal, business calls typically begin with a greeting; carry this courtesy when calling the US.
Document call times and time zones in writing to avoid future scheduling confusion.

TROUBLESHOOTING

Common Issues and Solutions

If your call fails or encounters issues, these tips will help you resolve them quickly.

Call won't connect or drops immediately

Check your internet or mobile signal strength. If using a browser-based calling service, verify your connection. Try the call again after a few seconds. If the problem persists, verify the 10-digit number is correct.

Recipient says the number appears blocked or unknown

International calls may display as unknown or with a country code prefix on the recipient's phone. Ask the recipient to check caller ID carefully. Some US carriers label international calls as 'International' or show a +221 (Senegal) prefix.

Dialing format errors or invalid number message

Verify you have entered +1 (country code), the 3-digit area code, and the 7-digit local number. Do not include extra zeros or special characters. Example: +1-212-555-0147 is correct; +1-0-212-555-0147 is not.

Toll-free numbers (1-800, 1-888) don't work

Many US toll-free numbers are not accessible from outside the United States. If you need to reach a business, ask for a main line number (non-toll-free) or email contact instead.

High call costs or unexpected charges

Use a service with transparent per-minute pricing so you know the cost upfront. Avoid traditional mobile network international rates, which can be expensive. Compare calling services to find affordable options.
