BBC News LinkCar licence plates which bear the sequence SN07 were banned from the streets of Edinburgh because they are "offensive", it has emerged.
The plate had been due to follow on from the SN56 registration in March.
Licensing officials at the Driver and Vehicle Licensing Agency (DVLA) changed the plate to TN07 to avoid it being similar to the word "snot".
The change means that cars registered in the capital are the only ones in Scotland not to begin with an S.
A DVLA spokesperson said the decision to change the plates was taken to avoid offending car buyers in the capital.
She added: "It is our policy that any registration mark that can be construed as being offensive to people will be suppressed.
"In this case, the SN07 marks would have been too similar to the word 'snot' and, as that could possibly offend some buyers, they were replaced with new TN07 registrations."
