Phone Number Formats to Call Baltimore from Canada

From Canada, dialing a number in the US is the same as dialing another number in Canada. This is because Canada and the United States both use the same telephone numbering system called the North American Numbering Plan.

As in Canada, all United States phone numbers are 10-digits long and include a 3-digit area code and 7-digit local subscriber number. This is true for both mobile phones and landline phones.

Increasingly in the US, the same region may have multiple area codes. Local subscriber numbers are unique within an area code. Please check here for more information on Baltimore area codes.

Like Canada numbers, United States phone numbers may be written to include a leading ' 1 '. This ' 1 ' can serve as either the United States country code for inbound international calls or as a national direct code for national long distance dialing in the US.

If the Baltimore phone number you have does not contain the full 10-digit phone number, then you'll need to double check to find the correct number.
