The 01633 telephone area code covers the city of Newport and surrounding areas in the United Kingdom. Before PhONEday the area code was 0633, which was originally dialled as "0NE3" where the "NE" were formed from the first two letters of NEwport on the telephone dial.[citation needed] In common with all other British area codes the initial '0' is a trunk prefix that is dropped when dialling from abroad.
