County Identification

You can obtain a county identification card by going to the Old Courthouse in Trenton or to the County Connection in Hamilton Township. You will need your original birth certificate, original social security card, and three items that have been mailed out to you within the last 60 days that prove your home address

You must provide a social security number, show proof of age, and proof of residence in Mercer County (so you can only do this after you are released).
