The Post Office has announced the changes that will be in place throughout the duration of the TT fortnight.
Residents living on the TT course have been reminded that during race week their usual deliveries will be significantly disrupted.
This will stretch from Saturday 6th to Friday 12th.
For those affected areas deliveries may - in some cases - occur the day after the scheduled races.
On these non-race days, there will be a complete delivery with a possibility of delays.
Throughout the fortnight, all postal staff will wear high-visibility jackets to ensure bikers can clearly see them on the roads.
All Post Offices will be open as usual during TT week - including Senior Race Day.
