Formby residents are this week receiving a letter from Royal Mail informing them that 'Formby' could soon be part of the town's official postal address.
At present, although some people may put 'Formby' on their mail, it isn't officially part of the address.
Now the postal service is consulting the people of the town on whether they would approve the change.
If fewer than 20% of people oppose the change by returning the reply card which is enclosed with the Royal Mail letter, then the postal address will be officially amended to include 'Formby'.
But, if more than 20% object a ballot will be held of affected addresses and the change will only be made if 50% of those balloted respond and of these a majority is in favour of the change.
Formby MP Bill Esterson said he thought many people in Formby would be in favour of adding 'Formby' to their official postal address.
Bill said: "Most people in Formby already add Formby to their address, so I'm sure lots of people will be in favour of this change. Although, I would question why the Royal Mail is spending money on this issue at such a tough time for many people.
"Sefton Council, the Parish Council and the Chamber of Commerce have already given their seal of approval to the change and Royal Mail are now simply making sure that it is something which has the support of this community."
The MP said that he had had calls from people who have been left confused by the letter from the Royal Mail caused by some mistakes in the letter.
Bill said: "Some people have been concerned and contacted my office to get clarification. But the simple fact of the matter is that the word 'Formby' will be formally added to the address recognised by the Royal Mail.
"But because of a mistake by Royal Mail in their letter to residents, the word 'LIVERPOOL' appears above the word 'Formby' on the proposed address, which is daft, and the Royal Mail has forgotten to enclose the reply cards, making the consultation more difficult. A new letter is being sent out this week.
"When I contacted Royal Mail about this, they immediately apologised and are now resending the letters with the errors rectified and the cards enclosed.
"This is an unfortunate mistake which will incur further costs for Royal Mail at a time when they can least afford it and I worry that it is the hard pressed residents of Formby and elsewhere who will end up paying for the mistake in increased charges."
