What will happen if residents and businesses dial a seven-digit number after this date? + -

How should a telephone number be written? + -

  • When written or printed, the 10-digit telephone number should be visually separated by dashes, spaces or periods in accordance with international standards (e.g., 709 123-4567 or 709-123-4567). The area code should not appear in parentheses since this may lead the caller to believe the area code is optional.

Can people continue to dial 9-1-1 in case of emergency? + -

  • Yes. The 9-1-1 emergency number, where available, will not change in any way and will still require only three digits.

If someone accidentally dials “1” before the 10-digit phone number when making a local call, will long-distance charges apply? + -

Will long-distance calls be affected? + -

  • Long-distance calls will continue to be made in the same manner. Simply enter “1” followed by the 10-digit number.
