A Tesco community noticeboard in Stalham tells residents 'Your Council' is North Walsham - nine miles away.
Stalham has its own town council which meets once a month in the town hall, just a short walk from the noticeboard.
Fed-up members of Stalham Town Council first asked the supermarket to correct the mistake a year ago but nothing had been done, councillors heard at their meeting this week.
Clerk Susan Wellerd is to write again and ask for Stalham Town Council's details to replace those of North Walsham.
The noticeboard, on a wall near the entrance to Tesco, gives North Walsham Town Council's address, telephone number, and website information.
