There are 21 counties in the State of New Jersey. Residents of most of these counties can apply for a county ID to supplement the state-issued driver's license or identification card. As of 2009, Somerset County no longer issues county IDs due to federal security requirements for government-issued identification enacted by the United States Department of Homeland Security. However, if you live in a county that still issues IDs, you can get a local identification card with a quick trip to the office of your County Clerk.
Visit the State of New Jersey's online alphabetical directory of official county and municipal websites. Browse to the website of the New Jersey county where you live to download a county ID application form. Website organization varies from county to county. Click on the navigation link that says "Office of the Clerk," "ID Cards" or "Forms."
Download the form and read the requirements to make sure you qualify. You must be a citizen by birth, a naturalized citizen or a resident alien of the United States and a resident of the New Jersey county in question. Some counties do not consider you a resident if you have not lived within the county lines for at least six months -- regardless of how long you have lived in New Jersey.
Collect the required supporting materials that prove your residency and eligibility for an ID in your county. These typically include a valid bird certificate with a raised seal, a naturalization certificate or a resident alien card. Additionally, you'll need one of the following to prove residency: a valid New Jersey Motor Vehicle License, a voter registration card or a lease agreement.
Complete the county ID application form on your computer using the PDF reader of your choice. Save and print the form upon completing it. If the PDF doesn't have fields in which you can type, print the form and complete it by hand. Most applications ask for your name, home address, date of birth, height, weight, eye color, hair color and signature. Do not sign the application form yet.
Go to the address listed for the office of the County Clerk on the application form and wait in the appropriate line.
Sign the form when the county employee instructs you to do so, and give her the application fee. An employee will take your picture and make you an ID card.
