Dialing formats#

The dialing format used to reach a toll-free number depends on the country and network from which the call originates. National toll-free numbers use a country-specific access format. Universal International Freephone Numbers (UIFNs) use country-specific international access prefixes followed by the 800 country code and the eight-digit UIFN.

Use this reference to identify the format that a caller should dial. These are caller-facing access formats. They do not change the DID itself, which DIDWW represents in E.164 format as the country code, area code, and subscriber number without + or formatting separators.

* The number uses one of the listed formats, depending on the interconnection it operates on. To confirm the dialing format for a specific number, contact support@didww.com.

Note

A country can use different access prefixes for toll-free numbers and UIFNs. Use the format listed for the service being called. When several formats are listed, the working format can depend on the originating network or carrier.

Examples#

  • To call a United States toll-free number, use the format 18xxxxxxxxx and replace each x with the remaining digits of the number.

  • To call a UIFN from the United States, dial 011800xxxxxxxx. The 011 international access prefix is followed by the 800 country code and the eight-digit UIFN.

  • To call a UIFN from Australia, dial 0011800xxxxxxxx. The international access prefix is different, but the 800 country code and eight-digit UIFN remain the same.
