DID Number Restrictions (Country)

The table below reflects up-to-date virtual number restrictions. Just as some new entries may appear, restrictions may be lifted. For this reason, when categorized "possibly unreachable," this limitation might not affect all users. Unfortunately, these conditions cannot be circumvented on a case-per-case basis—no exceptions can be made.

The countries in the table are ordered alphabetically. Some countries may be subject to more than one service restriction.
