The place to get your car registered depends on your location, but generally, you must register your car at your local motor vehicle or transportation department office. For example:

• In Georgia, you register your vehicle at your County Tag Office either in person or by mail. New residents have a 30-day window to register, while residents buying vehicles have specific deadlines. Required documents typically include proof of ownership, insurance, identification, and payment for fees and taxes.

• In New York, vehicle registration is done at a DMV office. If buying from a dealer, they may handle it for you. You need to insure your vehicle first and bring proof, along with documents and fees, to register at a DMV office.

• In the UK, vehicle registration is handled by the DVLA. Dealers often register new vehicles. For used vehicles, the seller usually registers the vehicle online or by post.

• In Texas, registration is done via your county tax office or approved substations. Registration renewal notices guide you on necessary documents, which include proof of insurance and inspection certificates if applicable.

If you provide your specific location or state/country, more precise instructions can be given. But generally, visit your local motor vehicle or transportation department office or website to find where and how to register your car. The process typically requires proof of ownership, identification, insurance, and payment for fees and taxes.
