Hi

two options
once you've typed your postcodes, select them and go into format / cells -
on the numbers tab, click on custom and type 00000 then press OK

or
when you're entering the "numbers" type a ' before them e.g.
'01234

or
before typing the postcodes, select the column where you're going to type
them and choose format / cells / text.

the first method leaves your numbers as numbers (ie you can add them up if
you wish), the second and third methods converts them to text.

Cheers

I need to have zip codes in a spreadsheet, but when I type in the zip code,
the zeros at the beginning disappear. How do I prevent this from
happening.

For example, 01234 automatically turns into 1234 which won't be the
correct
zip code when I mail merge the information.
