Are you curious about the inner workings of the 231 area code? Let’s break it down step by step

Calls in the 231 area code are routed to the telecommunications infrastructure that manages phone numbers within that specific area. Here are the ways it works.

Structure

A typical phone number in the 231 area code follows the format:

(231)NXX- XXXX

Where, 

  • 231 is the area code.
  • NXX is the exchange code, ‘N’ is a digit from 2-9, and ‘X’ is any digit from 0-9.
  • XXXX is the subscriber number, which can be any four-digit number.

How they work?

1. Dialing Within the Same Area Code:

  • When making calls within the 231 area code, you must usually dial the 7-digit number (NXX-XXXX). However, due to the growing demand for phone numbers, 10-digit dialing (area code + number) is becoming increasingly common.

2. Dialing to a Different Area Code:

  • If you want to call a number in a different area code, dial 1 + the area code + the 7-digit phone number (1-231-NXX-XXXX).

3. Local and Long-Distance Calls:

  • You don’t have to dial ‘1’ before the number in local calls within the same area. Even within the same area code, long-distance calls typically require ‘1’ before the number.

4. Calling From Mobile Phones:

  • Whether the call is local or long-distance, mobile users must dial whole 10-digit numbers.

5. International Calls to 231 Area Code:

  • To call a 231 number outside the United States, the caller must dial their international access code, followed by 1 (the country code for the US), then 231, and the 7-digit number (e.g., +1-231-NXX-XXXX).
