Your question is unclear. In general, access codes will be dialed before the telephone number. For example, if you want to use a long distance company other than your default, you dial the other company's access code first, followed by the number; for example, 101xxxx-1-406-555-0123.
Ireland's dialling code is 353. For Meath if you have the phone number it may start with 01 or with 046. So you would dial either of those, without the zero, and then the rest of the number. So dial your international dialling access code, then 353 for Ireland and then the number you have without dialling the first zero.
