Newquay's Central Square Post Office is set to move to Spar on Tower Road.
The Post Office says it is restoring the service to the community when the Fore Street branch closes in March.
The relocated branch will be renamed Tower Road Post Office and will open its doors on Thursday, 8 May. The company says it will operate with significantly longer hours than before - around 84 hours per week.
In a statement, a spokesperson said:
"We are keen to re-open the branch as soon as possible and so we have decided to go ahead with our plans. The opportunity to give feedback on access into and within the premises will close on 19 March. Customers can share their views during the consultation online at postofficeviews.co.uk with the branch code 443555."
Feedback can also be submitted via email at comments@postoffice.co.uk, by post to Freepost YOUR COMMENTS, or by phone at 03452 66 01 15. A Textphone service is available at 03457 22 33 55.
