ROYAL Mail is to make changes to delivery routes served by its Sheffield North team - meaning some households and businesses will receive their post later.
The centre serves the S6 and S35 postcode areas.
A Royal Mail spokesman said: “The way in which we communicate with each other has changed dramatically.
“Unfortunately, fewer letters are now posted every day and Royal Mail needs to organise its delivery routes to be as efficient as possible.
“We also deliver more larger items and so we are investing in new equipment to carry these items to customers even more securely.
He added: “Royal Mail will continue to deliver in the morning and for a longer period during the day.
“Many customers will continue to get their mail by lunchtime.
“The time customers receive mail will depend on where they live on the new delivery route.
“This may be later or possibly earlier than current delivery times.”
