Phone numbers in Paraguay have 9 digits. The first two or three digits are the area code, the remaining six or seven digits are the subscriber number.

To make local calls inside Paraguay, the 7- or 8-digit subscriber number is used. To make inter-provincial calls, you must use an access prefix ("0"), followed by the 9-digit phone number.

The international call prefix is 00PQR, where "PQR" is a 3-digit number used to select the long-distance company that will carry out the call.

Numbers starting with the digit "1" are used for special services
