We are pleased to offer our customers who are renewing their registrations the convenience of submitting renewal requests and payments online. Visa, MasterCard, American Express, and Discover credit and debit cards, and electronic checks are accepted for vehicle registration renewal payments. 

How Does This Work?
Our service is only available to Portsmouth residents who wish to renew their registrations. It is not available for new, first-time, or plate transfer registrations.

Please have the following items handy before continuing:

  • Your vehicle renewal notice letter, which we will mail to you about six weeks prior to your registration's expiration date
  • Your Renewal ID (10 digit number); and Code (6 digit number) which are printed on your letter; and
  • A valid email address.

In most cases, your registrations will be processed and mailed back to you within 2-4 business days of submitting your online payment. 

Use of this service is subject to the Terms of Service listed below.

Terms of Service

By using this service, you confirm that you understand and agree to the following terms of service:

Submitting your request to renew your vehicle registrations is not the same as registering your vehicle. Online submissions do not constitute a contract or requirement for the City to comply with those requests. Until you receive your official registration form and decals, your vehicle is not considered registered. Missing or incorrect information, data transmission problems, and other causes may delay or prevent the processing of your registrations.

A service (convenience) fee will be charged to cover the costs of processing online payments. You will have the opportunity to view the service fee prior to confirming your payment. For credit card transactions the service fee is either $1.95 or 2.95% of the transaction amount, whichever is greater. For electronic check (ACH/EFT) transactions the service fee is $0.40. There is also a $0.50 mailing fee added to each vehicle.

In the event of any problems or questions, we will attempt to contact you, but the City is not liable if, for any reason, we are unable to do so or if you do not respond to such communications. It is your responsibility to contact us if you have not received your registrations within 10 days of your online submission, and to comply with State of NH Laws regarding the registering and operation of your vehicles.

New: See the information below regarding our new online payment service which now includes the option for electronic paperless billing!
