Royal Mail delivery delays see 28 UK postcodes affected

The postage company says while it aims to deliver to all addresses we have mail for, six days a week, in some local offices, this may not be possible.

This may be due to local issues such as high levels of sick absence, resourcing, or other factors.

Royal Mail has issued a warning of delays across these 28 postcodes today, Monday, December 22.

The company is reminding the public to remain extra vigilant during the festive season because, often at this time of year, it sees an increase in online scam attempts as fraudsters look for opportunities to steal money and valuable information from people expecting a delivery.

Royal Mail has launched a stamp scanner to provide extra reassurance to customers who may be unsure about whether a stamp is counterfeit or not.

Customers who download the app can use it to check whether it is a known counterfeit, preventing them from inadvertently becoming victims of fraud.
