7-Digit Dialing in the U.S.


Last Updated: 08/03/2017 Back to Topic All Articles

In those areas of the U.S. where 7 digit dialing is still supported, callers calling the tracking numbers can be connecting using just 7 digits but its completely dependent upon their calling carrier. (i.e. their cell phone carrier or house phone carrier etc) so you will likely have some callers who will need to enter all 10 digits if they are calling from outside the calling area, from a cell phone etc.

If you are in an area that still has 7-digit dialing, the best approach is to provide the 10 digit format so that callers who are required to enter all 10 digits have the digits they need to make the call. For example, marketing materials could read something like: Dial: (410) 123-4567.

Dialing a tracking number using 10-digit dialing does not automatically mean that calling the number will incur long distance charges, and if you can dial a number locally using 7-digit dialing, then dialing the number with 10-digit dialing will also be a local call.

Here are the potential dialing scenarios:

  • You are able to call a number locally using 7-digit dialing: 10-digit dialed call will be local.
  • You are not able to call a number using 7-digit dialing, but it is in your local calling area: 10-digit calls to that number are local.
  • You are not able to call a number using 7-digit dialing, and it is not in your local calling area: 10-digit calls to that number are long distance.
