Where to mail ServiceOntario health card (OHIP) forms
Mail your OHIP health-card change-of-information form to: ServiceOntario, PO Box 48, Kingston ON K7L 5J3. Careful — ServiceOntario uses a different Kingston box, PO Box 9200 (K7L 5K4), for driver and vehicle licensing correspondence, and mixing the two up is the easiest way to delay your request. New OHIP registrations cannot be mailed at all; they are in-person only.

How to mail it, step by step
- 1
Identify which Kingston box your form needs
Health-card (OHIP) change-of-information forms go to PO Box 48, Kingston ON K7L 5J3. Driver and vehicle licensing correspondence goes to P.O. Box 9200, Kingston ON K7L 5K4. The recipient address is usually printed on the form itself — follow it exactly.
- 2
Complete the change-of-information form
Download the current form from Ontario.ca, fill in your health number or licence details, and sign where required. Incomplete or unsigned forms get returned, which restarts the clock.
- 3
Double-check the postal code
K7L 5J3 is the health-card box; K7L 5K4 is the driver and vehicle box. A one-character slip sends your form to the wrong processing stream.

Mail it without a printer
Upload your completed form to PostPal — $6 flat, printed and deposited with Canada Post the next business day. Keep the Confirmation of Mailing email as proof of when your update was sent.
Common questions
Where do I mail my OHIP health card change form?
Mail it to ServiceOntario, PO Box 48, Kingston ON K7L 5J3. This box handles health-card change-of-information forms, such as updating the address or name on an existing OHIP record.
Can I register for a new health card by mail?
No. New OHIP registrations are in-person only — you must visit a ServiceOntario centre with your identity and residency documents. Mail is only for changes to an existing health-card record.
Why are there two ServiceOntario PO boxes in Kingston?
They serve different programs. PO Box 48 (K7L 5J3) processes OHIP health-card forms, while P.O. Box 9200 (K7L 5K4) handles driver and vehicle licensing correspondence for the Ministry of Transportation. Send your form to the box that matches the recipient name printed on it.
Where do I mail a driver’s licence address change or permit stub?
Driver and vehicle licensing correspondence goes to ServiceOntario / Ministry of Transportation, P.O. Box 9200, Kingston ON K7L 5K4 — not the health-card box. Check the recipient name printed on your specific form before addressing the envelope.
What happens if I send my form to the wrong Kingston box?
It will usually be rerouted internally, but expect delays — the two boxes feed different processing streams. Verify the postal code (K7L 5J3 for health cards, K7L 5K4 for driver and vehicle) before you mail.
How do I prove I mailed my ServiceOntario form?
Keep a copy of the form and dated proof of mailing. PostPal emails you a Confirmation of Mailing when your letter is deposited with Canada Post — useful if your update has not appeared after the expected processing time.
