The 01720 area code is used for Isles of Scilly (County of Cornwall) and the areas directly surrounding Isles of Scilly, which includes 5 distinct locations. Most 01720 numbers are used for landlines. However, they can also be purchased by companies or organizations to be used for services that don’t have any connection to the Isles of Scilly area.
Previously, the area used 0720 as their area code. This changed in April 1995 during the phONEday event, where it was changed to the 01720 area code to accommodate the growing population and supplement the shrinking supply of phone numbers in Cornwall.
